How the Projector Works
The projector accepts video input signals for projection onto front or rear flat
screens. High brightness light is generated by an internal Xenon lamp then
modulated by three DMD (digital micromirror device) panels that provide digitized
red, green or blue color information. Light from the “on” pixels of each panel is
reflected, converged and then projected to the screen through a single front lens,
where all pixels are perfectly superimposed as a sharp full-color image.
The following listed items are shipped with your projector. Ensure you have received all
these items before using your projector.
1.2 Components
• User’s Manual
• Programmable theater master remote (includes four, 1.5V AAA batteries)
• Power cord
• Warranty Card

SECTION 2
Installation & Setup
The instructions provided here are for those that are familiar with the projector and wish to
quickly set it up and use it temporarily. Refer to the remaining subsections of this manual
for a more complete setup.
2.1 Quick Setup
Step 1 ➤
Install the Projection Lens
The projection lens is shipped separately from the projector and must be installed prior
to setting up the projector. Install the projection lens as described in 4.5 Replacing the
Projection Lens.
Remove the lens plug from the lens opening in the projector before installing the
lens.
Remove the lens when shipping the projector and reuse the lens plug to prevent
dust and debris from entering and settling on critical optical components.
Step 2 ➤
Position the Projector
Place the projector on a sturdy, level surface and position it so that it is perpendicular to
the screen at a suitable distance. In general, the further back the projector is positioned
from the screen, the larger the image will be.
If required, you can level the projector by adjusting its three feet. With the projector
positioned perpendicular to the screen the image will appear rectangular instead of
keystoned.
For more detailed instructions on positioning the projector refer to Projector Position and
Mounting later in this section.
Step 3 ➤
Connect a Source
Located at the back of the projector is the input panel where all source connections are
made. Each input is clearly labeled for easy identification. Using the appropriate cable(s),
connect your source. Connect RGB and YPbPr sources to INPUT 1 located in the upper
right corner of the input panel. Use the DVI-I connector at INPUT 2 to connect analog
or digital display signals. INPUTS 3 and 4 (Composite and S-Video) are available but
generally not used since these signals would be input to the included DHD Controller.
NOTE: One of the available optional input modules can be installed at INPUT 5 or INPUT
6 for additional connections.
Refer to 2.3 Connecting Sources for more details on connecting a specific source.

Step 6
➤
Connect the Power Cord
The North American rated power cord is provided with each projector.
Step 7
Plug the power cord to the AC receptacle located on the right hand side of the projector
and the 3-pronged end into a grounded AC outlet. The input voltage to the projector
must be capable of 100 – 240 VAC in 1000W models (VX-40d and VX-60d) and 200240VAC in 1200W models (VX-50d and VX-80d). (See also Section 6 – Specifications for
complete details on all power requirements.)
Use the approved North American-rated power cord supplied with the projector. If you are
connecting to an area outside of North America make sure you are using an appropriately
rated power cord.
Turn the Projector ON
Press the
POWER button on either the remote or built-in keypad to turn the projector
on, or turn the power on the DHD Controller (after fully connecting it to the projector),
which will turn on the projector automatically. Wait a few minutes to allow the projector to
warm up. The LED status window displays an active pattern of segments to indicate the
projector is changing its state from powered down to powered up. The message “On”
appears in the display when the projector has completed its initialization and is ready for
use.
Select a Source
Press one of the input keys on the remote or built-in keypad to select and display the
image for the source. With the DHD Controller, this would be either RGB (Input 1) or DVI
(Input 2).
Adjust Image
Press Auto to initiate an automated process in which the projector optimizes critical
display parameters such as size, position, pixel tracking etc. for the source selected.
You can also access the menu system and adjust these and other image settings by
pressing
on the remote.

2.2 Installation
Considerations
Installation Type ➤
Proper installation of your projector will ensure the quality of your display. Whether you
are installing a projector temporarily or permanently you should take the following into
account to ensure your projector performs optimally.
Choose the installation type that best suits your needs: front or rear screen, floor mount
or inverted mount.
Front Screen, Floor Mount Installation
Advantages
• Easy to set up
• Can be moved or changed quickly
• Easy to access
Considerations
• Shares floor space with audience
Front Screen, Inverted Mount (ceiling) Installation
Advantages
• Does not take up audience space
• Projector is unobtrusive
• Projector cannot be accidentally moved
Considerations
• Installation is more permanent
• It is more difficult to access the projector
Rear Screen, Floor Mount Installation
Advantages
• Projector is completely hidden
• Projector is easily accessed
• Usually good ambient light rejection
Considerations
• Requires separate room
• Installation cost is usually higher
Rear Screen, Inverted Mount (ceiling) Installation
Advantages
• Projector is completely hidden
• Usually good ambient light rejection
Considerations
• Requires separate room
• Installation cost is usually higher
Rear Screen, Floor Mount with Mirror
Advantages
• Projector is completely hidden
• Usually good ambient light rejection
• Requires less space behind screen than other
rear screen installations
Screen Type ➤
Considerations
• Requires separate room
• Installation cost is usually higher
Front Screen Installations
In front screen installations the projector and audience are positioned in front of the screen,
which can be flat or curved.
Flat screens are recommended with this projector. They offer a gain of about 1 with a
viewing angle just less than 180°. This type of screen reflects incident light equally in all
directions so the audience can see the display from various angles.
Curved screens have a gain greater than 1 with a viewing angle much less than 180°.
This type of screen does not reflect incident light equally in all directions instead it is
concentrated in a viewing cone. The audience sitting within the viewing cone area will
see a brighter image than those sitting just outside this area. Runco generally does
not recommend use of curved screens with the Video Xtreme series due to excessive
brightness and uncorrectable geometrical distortion.
10
Section 2: Installation and Setup
Rear screen installations
There are two basic types of rear screens: diffused and optical.
A diffusion screen has a surface which spreads the light striking it. Purely diffused screens
have a gain of less than 1. The main advantage of the diffused screen is its wide viewing
angle, similar to that of a flat screen for front screen projection. This type of screen is
suitable when a wide viewing angle is required but there is low ambient room lighting.
Optical screens (e.g. Fresnel Lenticular) take light from the projector and redirect it to
increase the light intensity at the front of the screen. This reduces it in other areas. A
viewing cone, similar to that of a curved front screen installation is created. This type
of screen is better suited for brightly lit rooms where the audience is situated within the
viewing cone.
Screen size
Choose a screen size, which is appropriate for your lens and application. The size of the
room and viewing distance are the defining factors; a rule of thumb is that the primary
viewing distance be 1.5 x screen width.
To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect
ratio of the image (expressed as the ratio of its width to its height). Standard video from
a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR output with a 4:3
aspect ratio onto a 10-foot (3m) high screen, the width of the screen must be at least
13.3 feet (4m).
11
Section 2: Installation and Setup
Ambient Light ➤
The high brightness of this projector is well suited for locations where ambient lighting
might be considered less than ideal for projection. A typical room with ceiling lights and
windows rarely requires special attention. Contrast ratio in your images will be noticeably
reduced only if light directly strikes the screen, such as when a shaft of light from a window
or floodlight falls on the image. Images may then appear washed out and less vibrant.
In general, avoid or eliminate light sources directed at the screen.
Other Considerations ➤
Other considerations and tips that can help improve your installation:
• Keep the ambient temperature constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature may cause
drifts in the projector circuitry, which may affect performance.
• Keep the projector away from devices that radiate electromagnetic energy such as
motors and transformers. Common sources of these include slide projectors, speakers,
power amplifiers, elevators, etc.
Projector Position ➤
and Mounting
Throw distance
Throw distance is the distance measured from your projector’s lens to the screen. This is
an important calculation in any projector installation as it determines whether or not you
have enough room to install your projector with a desired screen size and if your image will
be of the right size for your screen.
You can quickly estimate the throw distance by taking the horizontal width of the screen
and multiplying it by the lens throw ratio. The result of this calculation tells you roughly how
far back the projector should be positioned from the screen in order to project a focused
image large enough to fill the screen. For example, using a 0.75:1 lens, throw distance
would roughly be 0.75 x screen width.

Figure 2.1 Estimating Throw Distance
Vertical and horizontal position
The correct vertical and horizontal position of the projector in relation to the screen
depends on the lens type and the screen size. Ideally, the projector should be positioned
perpendicular to the screen. This way, the image will appear rectangular instead of
keystoned (trapezoidal).
The vertical position of the image can be offset – that is moved above or below the
optical axis (lens center) by adjusting the fully motorized lens mount using the keypad. The
amount of vertical offset available depends directly on the lens installed in the projector
and can be slightly limited if horizontal offset has been applied.
Vertical offset can also be expressed as the percent of half the image height OR the
number of pixels of shift from lens center. Refer to Figure 2.2 for some illustrated examples
of vertical offset.
Table 2.1 along with Figure 2.3 show the maximum vertical offset of a lens or alternatively,
how much of your projected image will appear above or below lens center if the maximum
vertical offset is applied using that lens.

The horizontal position of the image can be offset – that is moved to the left or right of
lens center, by adjusting the fully motorized lens mount. The amount of horizontal offset
available depends on the lens installed and if the image has already been vertically offset.
Horizontal offset can also be expressed as the percent of half the image width – the
number of pixels of shift to one side of lens center. Refer to Figure 2.4 for some illustrated
examples of horizontal offset.
See also Table 2.1 along with Figure 2.5 which shows the maximum horizontal offset of

Section 2: Installation and Setup
Mounting
There are several methods for mounting the projector. Depending on your chosen
installation, one method may be more suitable than another. In typical front and rear
screen installations the projector can be mounted to a secure and level surface, such as a
table or cart. Carts are useful when moving a projector during a presentation or from site
to site. If possible, lock the wheels when it’s in position to prevent it from being moved
during a presentation.
CEILING MOUNT—The projector can also be inverted and suspended from the ceiling
using a specially designed ceiling mount fixture. This type of mounting is recommended
for fixed installations and for those that want the projector out of sight or have a limited
space for projector and audience.
Use only the Runco approved ceiling mount kit designed for your projector.
SPECIAL MOUNTING—The projector can be rotated (front-to-back) up to 360 degrees
and mounted without it affecting performance. However, the side-to-side tilt limit of
the projector must not exceed ±15 degrees. This tilt limit is required to ensure optimal
performance of the lamp. (Figure 2.6.)
������
�����
Figure 2.6

Section 2: Installation and Setup
Adjusting projector height
You can modify the height of the projector to remedy a slightly unlevel mounting surface
by adjusting the two feet threaded into the front bottom chassis. Turn each foot clockwise or counterclockwise until the project is level on all sides. (Figure 2.7.)
TURN
Adjust projector feet manually.
Figure 2.7
Folded Optics
In rear screen applications where space behind the projector is limited, a mirror may be
used to fold the optical path. See Figure 2.8. The position of the projector and mirror must
be accurately set — if considering this type of installation call your dealer for assistance.
Figure 2.8
19
Section 2: Installation and Setup
2.3 Connecting
Sources
Sources connect to the Input Panel located at the back of the projector. See Figure 2.9.
The upper right corner (INPUT 1) typically accepts an RGB signal from an external analog
RGB source, or it can also be used for YPbPr signals or additional video sources. Just
beside these BNCs, the DVI-I connector (INPUT 2) accepts digital or analog display
signals from a computer. Connect analog composite video at INPUT 3 or S-video at
INPUT 4 from devices such as VCRs, laser disc players or DVD players.
There are also several optional interfaces available for connecting other sources— these

Composite and S-Video ➤
INPUT 3 and INPUT 4 provide simultaneous connection of both a composite video
source (INPUT 3) and an S-Video source (INPUT 4), though typically these connections
would be made at the DHD Controller. See Figure 2.12.
Figure 2.12 Connecting Composite or S-Video sources
DVI Digital Video ➤
Use the DVI-I connector at INPUT 2 to connect either analog or digital video devices to
the projector. The DHD Controller can be input here as well; adjust the output setting of
the DHD Controller to DVI if use of this port is desired. Use a cable with DVI-I connectors
at both ends to connect devices that transmit digital and analog video signals such as
high-quality DVD players, satellite receiver and digital cable TVs.
NOTE: 1) To ensure true digital output from devices that transmit digital signals, connect
to the DVI-I connector. 2) DVI loop through is not available unless you have the optional
DVI Input Module installed at INPUT 5 or INPUT 6.

Communications
As desired, direct the projector’s IR remote keypad towards the projector’s IR sensors.
In normal operation, the DHD Controller will control the projector, but for setup and
calibration, use the projector remote.
➤
Remote Keypads
There are two types of serial ports available on the projector: RS232 and RS422. The
RS232 port is used for communication with the DHD Controller, and subsequently the
RS422 port will be unused. If the projector is ever used as a standalone unit, either port
could be used for serial control.
➤
Serial Port Connections
Connecting RS-232 from the DHD Controller
The 9-pin DIN connector labeled RS232 IN on the input panel is dedicated to serial
communication with the DHD Controller. Using the appropriate serial communication
cables and supplied adapter, connect the DHD Controller.
From DHD Controller
Figure 2.13 Connecting RS232 from the Controller

Section 2: Installation and Setup
Connecting RS-422
If you wish to control the projector with an automation system with RS-422 capability
and a DHD Controller is not used (not recommended), connect a RS-422 serial
communication cable between the automation system and the RS-422 port on the
projector. RS-422 is better suited for serial communication over long distances than is
RS-232 communication.
Use the RS-422 port only if your device had RS-422 capability — always consult the
literature provided with your equipment before connecting. Connecting to the RS-422
port with incompatible equipment could damage your projector.

Section 3: Operation
Lens Mount & ➤
Projection Lenses
The projector is built with a motorized lens mount that allows for easy lens control and
adjustment. This includes such functions as adjusting vertical and horizontal offsets, zoom
and focus. The lens mount can be fitted with any one of the available optional lenses – see
Section 6 — Specifications.
• Zoom and Focus — There are two internal lens motors that allow for quick
motorized adjustment of zoom and focus. Adjust zoom to fit the displayed image
on the screen and adjust focus to improve the clarity of the image.
• Lens Offset — Vertical and horizontal offset is performed on the lens mount
through the use of DC motors.
• Shutter — Standard on all models the shutter allows you to turn the screen
absolutely black when in the “on” state. Press the ‘mute’ button for 1-2 seconds
on the remote to operate the shutter.
• Optical Aperture — Enables adjustment of light output and contrast ratio.
NOTES: 1) The projection lens is shipped separately from the projector. 2) Use the lens
cap when transporting the projector to avoid scratching and damaging the lens, which
could affect your displayed image.
Input Panel ➤
All source connections are made to the input panel located at the back of the projector.
Connect RGB or YPbPr sources to INPUT 1, analog or digital display signals to INPUT
2, composite video to INPUT 3, and S-video to INPUT 4. Any of the available optional
modules can be installed in INPUT 5 and/or INPUT 6.
The status display is part of the built-in keypad located at the rear of the projector.
Cooling and Air Vents ➤
There are numerous air vents located around the projector. It is important these vents remain
unobstructed. Adequate airflow through the projector will prevent it from overheating.
Front & Top IR Sensors ➤
The two IR sensors located on the projector receive transmissions from the IR remote
from up to 100 feet away. It is important to keep the transmission path to these sensors
unobstructed for uninterrupted communications with the projector. The front IR sensor is
located next to the projector’s nameplate and the top IR sensor is located at the top of
the projector.
Lamp Door ➤
The lamp door is located at the back of the projector, which provides easy access to the
lamp module for replacement. See Section 4.4 for lamp replacement procedures.

Section 3: Operation
3.2 Using the Remote
or Built-in Keypad
➤
Keypad Commands
➤
Built-in
➤
The projector can be controlled using one of the following keypads:
IR Remote
• Built-in Keypad located at the back of the projector
• IR Remote
While each of the keypads provides complete control of the projector, they differ slightly
in their arrangement of keys and in what functions can be accessed directly with a key
press rather than requiring use of the menu system. You may find one keypad more
convenient than another for your specific installation and application.
To control the projector when signals from a remote keypad cannot reach the projector,
use the projector’s built-in keypad. The nearby LED display provides feedback indicating
current status and activities of the projector. Because the built-in keypad has fewer keys
than the remote keypad, certain projector functions are accessible only through the menu
system rather than via a direct key.
Figure 3.2 Built-in Keypad
Refer to the key descriptions provided for the IR remote – see Figure 3.3.
The IR remote keypad controls the projector by way of wireless communications from a
battery-powered infrared (IR) transmitter. Use the IR remote keypad the same way you
would use a remote keypad supplied with a TV or VCR. When making key presses, direct
the keypad toward the front or top of the projector. One of the two IR sensors on the
projector will detect the signals and relay the commands for internal processing.

Guide to Keypads ➤
Keep in mind the following guidelines:
• Press keys one-at-a-time; there are no simultaneous key combinations required.
• Note that two keys—Power and Shutter, are “press-and hold” keys that do not function
with a typical quick press-and-release key press.
• Hold arrow keys down for continuous adjustment/movement in one direction.
• If you press a key while the projector is still responding to the previous action, such as
during power-up, the second key press may not take effect.
Specific keypad commands are explained below:
Keypad commands ➤
Power ON/OFF
Press and hold for two seconds to toggle the projector on or off with a single keystroke. Or
press and release followed immediately by Power to guarantee the correct toggle (useful
if you are unsure of the present state).
NOTES: 1) After powering down, the lamp cooling fan remains on for approximately 5
minutes to cool the lamp. 2) It is a good idea to avoid turning a projector back on until it
has been off for a few minutes. Hot re-strikes of the lamp may reduce lamp life.
Test
Press Test to step forward through all internal test patterns and eventually the current
input. If you press Test and then cycle by using the and right arrow keys, you’ll be cycling
in either direction through the test patterns only, no input. Press Exit to get out of the test
pattern mode.
Auto
Press Auto to initiate an automated process in which the projector optimizes critical
display parameters such as size, position, pixel tracking, etc., for the current source.
These parameters are listed in Table 3.1. An Auto Setup can save time in perfecting a
display and you can modify the adjustments as desired. You should expect to perform
further calibration after ‘Auto’ is used; the ‘Auto’ function is a way to get the image ‘in the
ballpark’.

Section 3: Operation
3.4 Using Inputs and
Channels
NOTE: See Section 2, Installation and Setup, for details on connecting sources to the
projector.
The projector stores and automatically recalls up to 50 different channels (source setups)
for a variety of inputs. This memory feature allows you to define and conveniently use a wide
variety of customized setups rather than having to repeatedly re-configure the projector
for different presentations. Depending on what you have defined, each physical source
connection (i.e., input at the projector) can have several different channels associated with
it.
NOTE: Channels are pre-configured at the Runco factory for use with the DHD
Controller, and do not necessarily need to be changed. The following information
is only necessary if other sources are connected directly to the projector.
Do I Select an Input ➤
or a Channel?
INPUT — An input is a source physically connected at the projector. Input describes the
source signal according to which input slot it is connected.
SWITCHING INPUTS — Press the appropriate “direct” key — Input 1 , Input 2 , Input 3
, Input 4 , Input 5 or Input 6 to quickly display from one of the six inputs connected. The
image will be displayed according to the following:
If it is the first time you have used the source/input (or if you used the input but
did not define a channel by adjusting anything), the projector will recognize the new
input signal based on its frequencies and polarities, and will automatically display an
image according to default settings for such a signal. In general, the image from the
new source will be as large as possible without losing its aspect ratio. This and other
default image settings depend on the incoming source.
If you used the source once before and changed a display parameter such as
contrast, V-Position, etc., then a channel was automatically created and still exists in
projector memory (see below). Using one of the Input keys will automatically recall this
channel—and all its setup parameters—and update the display accordingly.
If more than one channel exists for the input, the image will be displayed according
to the setup parameters for the first channel with matching characteristics.
NOTE: Inputs 7 and 8 require the Dual SD/HD-SDI module in either of the projector’s
option slots. For their selection, see also 3.2 Using the Remote or Built-In Keypad.
CHANNEL — A channel is a collection of measurements, locations and settings that tailor
the display of a signal to your specific needs. Since source types and applications can
vary greatly, you will likely want to adjust and define a wide variety of parameters, such
as brightness, contrast, size, etc., in order to customize and optimize the display from or
for a particular source. For example, the display settings you choose for a VCR source
may be very different from those you choose for a high resolution computer source, or
one signal may simply vary from another signal used previously through the same input
location. Once you have adjusted a display parameter, such as pixel tracking or contrast,
all current settings are collectively stored in the projector’s memory as a unique 2-digit
channel, such as 0 9 . You can have numerous distinct channels available for the same
input, any of which can be selected by using the Channel key on the keypad followed by
the 2-digit channel number.
38
Section 3: Operation
Shown at right is a sample channel list as would
be available from Channel . This is typically called
the channel list.
➤
NOTE: The Channel key may display a channel list
or not, depending on what you have defined for
“Display Channel List” (see Menu Preferences
later in this section).
In order to access channels by using Channel on
the keypad, you must first create the channels.
See below.
Channel List
To use a new source with the projector, a new channel must be added to projector
memory so that the projector will respond properly to an input signal from that source in
the future. A new channel can be created automatically, as described here, or it can be
copied from an existing channel and then edited as necessary (see Copying or Deleting
Channels later in this section).
When you select a direct input ( Input 1 , Input 2 , Input 3 , Input 4 , Input 5 or Input
6 ), any existing channels in the projector are searched for matching input and signal
parameters – this only occurs if Auto Source is enabled on these channels. If no match
to the incoming input signal is found in currently-defined channels, a new channel is
temporarily created based on factory-defined defaults for this type of signal. The channel
number assigned is the lowest available number from 01-50.
NOTES: 1) An automatic channel will be discarded unless one or more of its parameters
are changed and will not appear in the channel list (see below). 2) If two channels have
the same distinguishing source characteristics except for the reversal of sync connectors
(i.e., H-sync and V-sync, are switched), they are still defined as distinct channels. 3) You
cannot define a new channel without an incoming signal.
If the incoming signal does match an existing channel, the image will be set up and
displayed as usual according to the parameters currently defined for that channel.
USING A CHANNEL: You can normally select a channel at any time by pressing Channel
(see right). If you want to prevent a channel from appearing in this list, you must edit the
channel as described in Channel Edit later in this section. Such a channel can still be
selected by entering its number as shown at right.
NOTES: 1) The current channel
is highlighted upon entering the
channel list, or, if this channel is not
displayed here, the first channel in
the list is highlighted. 2) Channels
created automatically do not
appear in the channel list unless a
parameter for the channel has been
changed.

numbers currently defined. The values in the far right columns
indicate horizontal and vertical frequencies—if someone has defined a name for this
channel, it appears here instead. Remaining columns contain details pertaining to each
channel setup, such as its switcher number (always 0 = projector), slot location, a variety
of icons indicating access to each channel, and an abbreviated description of each signal
type. See Editing a Channel Setup for details.
NOTE: If you have more than a handful of channels, use and to see the remaining channels
not visible in the initial display of channels.
SIGNAL TYPE — Either channel list, whether the Channel key list or the Channel Setup

Channel names can be up to 12 characters in length.
• CHANNEL NUMBER: A 2-digit channel number can be changed here.
NOTES: 1) If you enter a channel number that already exists, a dialog message appears
indicating that this number is already in use – assign a different channel number. 2) You
can define up to 50 channels.
• INPUT: 1-8, corresponding to where on the projector’s input panel the source is
connected.
• IN MENU: If checked (default, except for automatically defined channels with unchanged
parameters), this defined channel will then appear in the list available when Channel key
is pressed. If unchecked, the channel must be accessed via Channel on the keypad or
via the Auto Source function.
NOTE: Onscreen display of the channel list is an option that must be set in the Menu
Preferences menu.
42
Section 3: Operation
• AUTO SOURCE: If checked, (default), the projector can automatically locate this
channel when an incoming input signal matches. If not checked, the projector can locate
the selected channel only when it is directly selected via Channel on the keypad—and
a change in input signal will not result in a channel change.
• LOCKED: If checked, all of the image settings for this channel are disabled. If unchecked
(default), all available image settings can be adjusted as desired. You cannot use Auto
Setup with a locked channel.
• PREVIOUS CHANNEL: Select this option to see or change Channel Edit settings for
the previous channel in the Channel Setup list.
• NEXT CHANNEL: Select this option to see or change Channel Edit settings for the
next channel in the Channel Setup list.
The most commonly used options for image adjustments are accessed through two
menus: Size and Position ( 1 Menu )and Image Settings ( 2 Menu ), both of which appear
in the Main menu. From either of these two menus, you can change settings affecting the
image from the current channel by working with the appropriate slidebars, checkboxes
and pull-down lists. Exit will return to the previous menu (or to the presentation, if from
the Main menu) and accept any changes you may have entered. Settings are saved with
the current channel.
3.5 Adjusting the Image
From your presentation, you can access any of the individual options in these menus by
pressing Menu followed by the appropriate two-digit number representing their location
in the menu system. For example, press 2 3 Menu to quickly access the “Gamma” option
in the Image Settings menu.
Note that for certain options, you may prefer to use a “direct key” from presentation level
to go directly to a particular option without traveling through the menu system (note:
available for certain display parameters only). For example, press Contrast to access the
“contrast” slidebar immediately. Press Exit to return to your presentation.
NOTES: 1) To hide these “direct” slidebars, disable the “Display Slidebars” checkbox in
the Menu Preferences menu. 2) To hide the entire menu system from view, toggle the
on-screen display by pressing OSD .

Use Auto Setup ( Auto )
For a good and efficient first step in perfecting the image, press Auto . This initiates an
automated process in which the projector quickly optimizes critical display parameters
such as size, position, pixel tracking, etc., based on the type of incoming source data
detected. An Auto Setup can save considerable setup time, and you can still modify the
adjustments as desired using menu options described below.
Before You Begin
Section 3: Operation
Size and Position Menu ➤
In the Size and Position menu,
you can increase or decrease
the size of your image, change
its proportion (aspect ratio),
move the image to a specific
area of the screen, and refine
other related parameters. Use
Size and Position controls to
match the image precisely to
the screen used at the site.
Refer to “Using Slidebars and Other Controls” (earlier in this section) if you need help using
any of the options and controls. Changes made in the Size and Position menu are applied
immediately and are saved when you exit the menu (press Exit or Menu ).
Resize Presets
Select a Resize Presets option to quickly display an image in its native resolution or to
automatically resize an image to closely fill the projector’s native resolution of 1400 x 1050,
or to optimize the width or height
of your display. Size, Position
and Blanking parameters will
automatically adjust accordingly,
or if Blanking is set first, which
defines an Active Input Area,
Resize Preset scaling will occur
in this region of interest only.
Resizing options are explained in
detail below.
WHAT IS THE RESIZING DEFAULT? By default when displaying a new source, your
image will utilize as much of the projector’s display area (1400 x 1050) as possible for the
type of incoming source data, but with minimal or no changes to aspect ratio. See Select
“Default” below.
WHEN “CUSTOM” APPEARS: The “Custom” re-size descriptor automatically appears
in the Size and Position menu when any of the values for Size, Vertical Stretch, H-Position,
V-Position or Blanking do not correspond to those for a preset. This option is not offered
in the Resize Presets pull-down list.
• Select “DEFAULT” for most sources (factory default). The image will be centered and
displayed as large as possible depending on the type of source, as described below:
✔A 5:4 graphic image will enlarge to fill the screen height, and be centered between
narrow black side bars.
✔A video image or 4:3 graphic image will enlarge to fill the screen.
✔An anamorphic (16:9) image will fill the width and be centered between black
bars on top and bottom.
44
Section 3: Operation
• Select “NO RESIZING” to display the image in its native resolution, which may or may
not match the projector’s 1400 x 1050 resolution. For example, for a source with a native
resolution of 800 x 600, “No Resizing” will use the central 800 x 600 pixels and have a
black border—the black border areas are unused areas. See below.
• Select “FULL SIZE” to use all
pixels (1400 x 1050) for displaying
the image, regardless of source
or original aspect ratio. Incoming
source material having a different
aspect ratio than the projector
will be stretched for display.
• Select “FULL WIDTH” to fill
the projector’s display from leftto-right without changing the
original aspect ratio of the image.
Depending on the source, data
at the top and bottom may be
discarded (cropped), or the
display may have black borders
at the top and bottom (called
“letterbox”).
• Select “FULL HEIGHT” to fill
the display from top-to-bottom.
Depending on the source, this
may create
45
Section 3: Operation
• Select “ANAMORPHIC” to display an anamorphic image
in its native 16:9 aspect ratio. The image will fill the screen
from side-to-side and be centered between black bars at
top and bottom.
• Note: If using a 16:9 screen, you may have to go to the
‘Anamorphic’ mode after performing an auto setup.
Size
“Size” controls both the image width and height in tandem, maintaining the current aspect
ratio (proportion) of the displayed signal data.
Vertical Stretch
“Vertical Stretch” adjusts the height of the image while keeping the width constant. Use
“Vertical Stretch” to change the aspect ratio of the display.
Pixel Track
Steady flickering or several soft vertical stripes or bands across the entire image indicates
poor pixel tracking. Proper pixel tracking helps ensure that the image quality is consistent
across the screen, that aspect ratio is maintained, and that pixel phase can be optimized
(described below). Tracking determines the frequency of the pixel sampling clock, indicated
by the number of incoming pixels per line, so that all pixels generated by a particular
source are sampled.
NOTE: By default, the projector samples at the correct frequency for most sources.
For best results, use a good test pattern such as a smooth gray consisting of a clear
pattern of black and white pixels, or a similar “half on, half off” graphic image, such as
the Windows shutdown screen. Adjust the slidebar until the vertical stripes broaden to
the point where one large stripe fills the image. If the image still exhibits some shimmer or
noise, adjust Pixel Phase (below).
Pixel Phase
NOTE: Adjust “Pixel Phase” after “Pixel Tracking”.
Adjust pixel phase when the image (usually from an RGB source) still shows shimmer
or “noise” after pixel tracking is optimized. Pixel phase adjusts the phase of the pixel
sampling clock relative to the incoming signal.
For best results, use a good test pattern such as a smooth gray consisting of a clear
pattern of black and white pixels, or a similar “half on, half off” graphic image, such as the
Windows shutdown screen. Adjust the slidebar until the image stabilizes and each pixel is
clearly defined. You may notice that you can stabilize the image at more than one point—
i.e., you may find that the image appearance at “11” is identical to the image appearance
at “38”, thus you can use either setting.
If some shimmer from a video or HDTV source persists, use the “Filter” control to remove
high-frequency noise from the signal. See Image Settings.
46
Section 3: Operation
H-Position
This option moves the image right or left within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies in
relation to the total number of pixels available horizontally. This varies widely according to
the signal—watch the image while adjusting.
V-Position
This option moves the image up or down within the area of available pixels.
NOTE: The value shown represents where the approximate center of the image lies in
relation to the total number of pixels available vertically. This varies widely according to
the signal—watch the image while adjusting.
Advanced Size and Position — SUBMENU
This submenu consists of the following options:
ACTIVE INPUT WINDOW: This read-only value indicates the current size (i.e., area) of
your displayed data or “region of interest” as defined by the blanking controls. By default,
the projector automatically determines what portion of its full resolution to use, and pixels
in the surrounding borders are turned off. You can also specify a specific active input
window size by adjusting one or more “Blank” settings. For example, if you have blanked
(cropped) 100 pixels from both the left and right edges of an incoming source of 1400
x 1050, the remaining active input window will be reduced to 1200 x 1050. When using
SD or HD or a decoded video source at INPUT 3 or INPUT 4, the default blanking of “0”
defines an active input window of 720 x 483.
47
Section 3: Operation
BLANKING (TOP, BOTTOM, LEFT, and
RIGHT): Crop the image as desired so that
unwanted edges are removed from the display
(changed to black—see right). Blanking
defines the size of the Active Input Window,
or area of interest. Range of adjustment
depends on the source resolution and other
factors.
PLUG & DISPLAY (EDID): By default, a Plug & Play (EDID)
source outputs a signal according to the EDID information
provided by the projector. To override this information and
display in a different format (for example, if your Plug & Play
[EDID] device does not support the projector’s resolution and/or
frequency), select the desired Plug & Play (EDID) resolution from
the list.
Any daisy-chained projectors will also display according to the
chosen Plug & Play (EDID) format.
EDID = Extended Display Identification Data standard.
Image Settings Menu ➤
Use options in the Image
Settings menu to alter your
image without affecting its size
or position. Changes made to
the Image Settings menu are
applied immediately and are
saved when you exit the menu
(press Exit or Menu ). Options
not available for the projector
model or source are disabled
and appear dim (gray).
48
Section 3: Operation
Contrast
“Contrast” increases or decreases the perceived difference between light and dark areas
of your image (0-100). For best results, keep it under 50. If contrast is set too high, the
light parts of the image lose detail and clarity. If set too low, the light areas will not be as
bright as they could be and the overall image will be dim. For best results, start with a low
value and increase so that whites remain bright but are not distorted or tinted and that
light areas do not become white (i.e., are “crushed”).
NOTE: If the environment lighting changes, an adjustment of Gamma is recommended
(see below).
Brightness
“Brightness” increases or decreases the amount of black in the image (0-100). For best
results, keep close to 50. Start with a high value and decrease so that dark areas do not
become black (i.e., are “crushed”). Conversely, high brightness changes black to dark
gray, causing washed-out images.
Gamma
“Gamma” is a global setting that determines how gray shades are displayed between
minimum input (black) and maximum input (white) for all signals. A good gamma setting
helps to optimize blacks and whites while ensuring smooth transitions for the “inbetween” values utilized in other grays. Unlike “Brightness” and “Contrast” controls, the
overall tone of your images can be lightened or darkened without changing the extremes
and all images will be more vibrant while still showing good detail in dark areas when
using the “Gamma” control.
The normal gamma setting of 2.2 is correct for virtually all signals and conditions. If
excess ambient light washes out the image and it becomes difficult or impossible to see
details in dark areas, lower the gamma setting to compensate. This will improve contrast
while maintaining good details for blacks. Conversely, if the image is washed out and
unnatural, with excessive detail in black areas, increase the setting. Again, good gamma
improves contrast while maintaining good details for blacks and whites.
Filter
The proper filter setting is automatically set for virtually all signals,
and rarely needs to be changed. It applies a low pass filter for noise
reduction in the incoming input signal, particularly for HDTV or
SDTV. Applied in the analog domain before sampling, this filtering
removes high frequencies and thus reduces pixel phase noise (note this also reduces
signal bandwidth). Override only if standard pixel tracking and phase adjustments do not
adequately clear up a “noisy” video signal, or if a graphics signal appears overly “soft”.
Both instances indicate that “Filter” may be set to the wrong option.
49
Section 3: Operation
Detail
“Detail” adjusts the sharpness of a video image so that edges remain clearly defined. It
can be particularly useful if a significant “Noise Reduction” adjustment has caused the
image to appear too soft. Adjust until the display is as sharp as desired, keeping in mind
that because “Detail” adds some high frequencies back into the image, it can also reintroduce a certain degree of noise.
Noise Reduction
“Noise Reduction” is similar to the “Filter” control, but operates in the post-sampling digital
domain with a more subtle effect. Higher settings are most useful for clearing up noisy
RGB images such as those from a PC. Adjust as desired, keeping in mind that reducing
noise (which reduces high frequencies) may also soften the image.
Color Space
“Color Space” determines how the color components of an analog
input signal are decoded for accurate color in the display. Selecting
a color space option is useful only for analog signals connected to
INPUT 1, INPUT 2, INPUT 5 or INPUT 6. Although color space for
these analog signals is automatically determined by the projector, in some circumstances
you may wish to override this and manually set a specific color space.
NOTE: For digital signals or for signals connected to INPUT 3 or INPUT 4, the color
space function is entirely automatic and the pull-down list disabled.
The current color space appears in the Image Settings menu. Press to select a different
option:
• Select RGB unless you are using component video at INPUT 1, 2, 5 or 6.
• Select YPbPr (Video) with a standard definition televised signal (SDTV)
• Select YPbPr (HDTV) with a high definition televised signal (HDTV).
NOTE: When certain RGB signals are first connected, the projector may not initially
recognize them as RGB and will incorrectly decode their color information as YPbPr
(video). These signals, which appear magenta, can include:
• RGB signals in NTSC, PAL, SECAM frequency ranges
• Scan-doubled sync-on-green
• Scan-quadrupled sync-on-green
For these signals, change the Color Space to RGB.

Section 3: Operation
Video Options — SUBMENU
This submenu is used with video sources only
(INPUTS 3 or 4).
ENABLE DECODER AGC: Automatic Gain
Control (AGC) affects decoded video images
only. Enter a checkmark (default) in most
instances—this activates the decoder’s AGC circuit to ensure properly bright images.
Delete the checkmark if a decoded video image exhibits strange color artifacts such as
stripes in highly saturated colors, indicating an incompatibility between this source and
the AGC.
VIDEO STANDARD: For all but the more unusual video standards
available in the world, the projector automatically detects the incoming
horizontal and vertical frequencies and sets the projector’s processing
of this signal to the corresponding standard. The current video standard
name appears in the Video Options submenu, and includes an “A”
if it has been auto-detected. Press to view or select a different video
standard from those available to the projector—any that are disabled
have frequency characteristics that differ from those of the incoming
signal. Selecting a specific standard forces the projector to process the
signal according to this standard.
Standard
Where Used (SUBJECT-TO-CHANGE)
NTSC
N. America and Japan
NTSC 4.43
A tape-only standard for partially-translated hybrid signals
PAL

NOTE: Generally, use “Auto” for all instances EXCEPT: 1) a poor quality input signal or
2) a black-and-white video signal. In order to detect and display such signals, select the
relevant standard from the list.
INPUT VIDEO BLACK — This control
compensates for incoming elevated black levels
present in certain video signals, and ensures
that blacks in the display are neither crushed (i.e., where dark grays appear black) nor
excessively elevated (i.e., where blacks appear dark gray). By default, the projector
automatically determines the best setting according to the type of incoming video
signal:
• 0 IRE – Used for DVD output with “enhanced black”, SECAM, most PAL standards,
and Japanese NTSC.
• 7.5 IRE – Used for most NTSC video signals.
For some types of video, you can override the setting. The control is disabled for other
types of video (and all graphics sources). Generally, if black appears crushed when
brightness = 50, choose “0 IRE”. If black appears excessively elevated, use “7.5 IRE”.
51
Section 3: Operation
COLOR — This slidebar adjusts the color saturation level, i.e. the amount of color in
a video image. Lower settings produce less saturated colors — for example a setting
of “0” produces a black and white image. If the color level is too high, colors will be
overpowering and unrealistic.
TINT — This slidebar adjusts the red/green color hue for true color reproduction of
video signals connected to INPUT 3 or 4. For best results, adjust tint while displaying
an external color bars test pattern—otherwise, it is recommended that tint remain at its
default setting.
DECODER LUMA DELAY – This control affects any incoming composite or S-video
signal, delaying the luma signal (intensity) in relation to the chroma (color). In the image,
increasing the luma delay will move luma (seen as a shadow where colors overlap) to the
right slightly, with colors remaining in place. Decreasing this delay will move the shadow
slightly to the left. If necessary for your current source, adjust so that no shadows occur
with adjacent colors.
Input Levels — SUBMENU
NOTES: 1) Because the projector automatically optimizes input levels for all but the most
unusual of sources, it is recommended that only experienced users use the Input Levels
submenu. 2) Before beginning, check that overall contrast and brightness settings are
near 50 and that color temperature is properly set up on an internal grayscale test pattern.
3) There must be at least 2 consecutive white pixels present in the image for proper “Auto
Input Level” function. Leave this control off after use.
Good RGB or input levels—
that is, the drives and
blacklevels for each of the
three colors, red, green and
blue—ensure that images
from analog sources other
than decoded video have
maximum contrast without
crushing black or white.
By default (and in an “Auto
Setup”),
the
projector
automatically determines the
best input levels by monitoring
image content and adjusting the controls appropriately—further adjustment is typically not
required to obtain proper blacks or whites. NOTE: This automatic adjustment requires at
least 2 consecutive white pixels in the image. Without these pixels, input levels may
produce skewed colors, particularly in nonvideo images.
However, for a very unusual source exhibiting one or more overly high blacklevels (typically
caused by a noisy source causing blacklevel spikes), an experienced user may prefer to
use the Input Levels menu (shown above). These adjustments, which together serve as
a calibration process compensating for differences in sources and cabling, enable an
experienced user to perfect the source image input levels and eliminate the “overshoot”
and “undershoot”. Note that Input Levels are of limited use with digital signals, but do offer
some ability to tweak poorly mastered source materials.
52
Section 3: Operation
AUTO INPUT LEVEL – Keep off for virtually all sources (default). Temporarily enter a
checkmark only if you are an experienced user and you have an unusual source that
you feel needs further color temperature and/or input level adjustment. After entering a
checkmark, wait for the six slidebar values to stabilize, then delete the checkmark and
exit. This compensates for incoming out-of-range drives (white) and blacklevels (black)
that would cause “crushing” of light and dark colors in the image.
BLACK LEVELS AND DRIVES - To check your image and adjust these controls:
1. Make sure overall “Contrast” and “Brightness” settings are both set to near 50.
NOTE: Not required for “Auto” adjustment.
• Contrast = 50 (approx.)
• Bright = 50 (approx.)
2. Check the color temperature setup using an internal grayscale test pattern,
making sure to obtain a neutral grayscale. NOTE: Not required for “Auto”
adjustment.
3. Confirm that you are using an analog source not connected to INPUT 3 or INPUT
4, as Input Levels are not applicable for digital sources or sources going through
the decoder. A grayscale is recommended.
4. If the blacks and/or whites appear OK, input levels do not need adjustment. If
black levels are too high (and/or whites are too low, which is rare), you likely have
a noisy source that is producing skewed input levels. Continue with Step 5.
5. Temporarily enable “Auto” in the Input Levels submenu. Wait for all 6 values to
stabilize. Alternatively, do not use “Auto”—reduce blacklevels manually instead.
Judge by eye and change one or more of the six levels as necessary to obtain
proper blacks and whites. You may want to see only a certain color while
adjusting—use the “Color Enable” option (described below).
6. Delete the “Auto” checkmark and leave the Input Levels menu.
AUTO COLOR ENABLE – When a checkmark is present, selecting a specific blacklevel
or drive to adjust will automatically enable the corresponding color in the display. Delete
the checkmark to see all colors.
CLAMP LOCATION – This option (formerly known as sync tip
clamping) can brighten the image produced from certain highresolution, high-frequency graphic sources. For almost all sources,
the best clamp location is automatically selected by the projector.
Use the normal Back Porch location if the image is either sufficiently bright or overly
bright. Select Sync Tip if the image appears unusually dim, if there are horizontal streaks
across the image, or if there is significant color drift. This moves the clamping pulse from
the normal back porch location (which is likely too short) to the tip of the horizontal sync
pulse. Tri Level is typically recommended for an HDTV source where the back porch is
also short.
NOTE: Clamp Location is not used for video sources or any RGB source with sync
information included on the video (e.g., sync-on-green). Use Tri Level instead.
53
Section 3: Operation
COLOR ENABLE – Select which color or colors you want to see in the display, useful
while working with color temperature white levels or input levels.
NOTES: 1) Input levels apply for the current source only, but for any color temperature
used. 2) Assuming that color temperature has been set up based on the internal test
patterns, you can then set up input levels for a given source so that it matches the color
temperature of the internal test patterns.
PEAK DETECTOR – The Peak Detector is a fast method for defining individual input
levels, and can improve the accuracy of input levels set by the Auto Input level function.
Enabling the Peak Detector activates a special operating mode for detecting only pixels
that are considered black or white—all other levels are displayed as a mid-level gray.
When used with a smooth grayscale pattern in which black and white are known to
be at opposite edges of the image, you can watch these isolated areas while adjusting
individual blacklevels and input drives until both black and white edges are just visible and
distinguished from neighboring pixels. Images from this source will then display correct
blacks and whites without crushing.
See Figure 3.13. Adjusting Input Levels Using the Peak Detector:
1. Display a 16 level grayscale test pattern from the desired external source, and
enter a checkmark in the Peak Detector checkbox. NOTE: The “Peak Detector”
will initially render the grayscale as a uniform gray field before adjustment.
2. Display one primary color (use Color Enable to select).
3. For the current color, adjust its corresponding “Blacklevel” slidebar just until a
single band of black appears at one edge of the screen. This band represents the
first band of the grayscale pattern, which should be 100% black. Do not adjust
too far.
4. With the same color still active, adjust its corresponding “Input Drive” slidebar just
until a single band of color appears at the opposite edge of the screen. This band
represents the last band of the grayscale pattern, which should be 100% white
(or the current color, if a certain color is enabled). Do not adjust too far.
5. Go back and check the black band—adjust the blacklevel slidebar if necessary.
Blacklevel and Input Drive adjustments are related, so you may have to go back
and forth until both bands are just optimized.
6. Repeat Steps 2-5 with the other two remaining primary colors. When each
primary color shows one optimized black band and white (or colored) band, the
input levels for this source are correctly set. Upon exiting the Input Levels menu,
the Peak Detector checkbox will clear.

Advanced Image Settings —
SUBMENU
GAMMA TABLE: This control selects
and applies the normal 2.2 gamma
setting or a user-defined “arbitrary”
(custom) gamma table that has been
previously downloaded to projector
memory (these custom gamma
tables—a.k.a. curves—are created in
Runco’s Arbitrary Gamma application
for the PC, and are downloaded via a
separate utility). Use of custom curves
can improve performance for certain
kinds of source input and applications.
Generally the best gamma curve is
one that produces maximum contrast, brightness and color performance for the current
signal and ambient lighting conditions.
NOTE: If no such curves have been defined and downloaded to projector memory, only
the “2.2, Normal” default gamma curve is available here—adjust as desired in the main
Image Settings menu.
SELECT COLOR ADJUSTMENT: In “Select Color Adjustment”,
choose an overall color performance for all images. The “Max
Drives” factory default simply drives all 3 colors at their maximum
level so that they are fully on and cannot be changed. The two
other pre-defined color adjustment choices—SD Video and
HD Video—apply a color gamut optimized for video sources
(standard or high-definition). Alternatively, you can specify a
color temperature, which enables the nearby Color Temperature
slidebar and applies its current setting (default = 6500K). If none
of the pre-defined “Select Color Adjustment” options or color temperatures suit your
application, select one of four color gamuts previously defined by a user (User 1, 2,
3, 4). A “User” option applies a customized color performance in which the user has
precisely set the hue and intensity of each color component in the Color Adjustment
by X/Y or Color Saturation submenus, and is most often needed with multiple-projector
applications. Select the color adjustment producing the best color accuracy for your
application and installation.
55
Section 3: Operation
To configure a “User” color adjustment (gamut), use either the Color Adjustment by X/Y or
Color Saturation submenu found in the Configuration menu under Geometry and Color.
NOTES: 1) “Color Temperature” defaults to 6500K until changed. All four “User” options
default to SD Video unless they have been redefined by the user. 2) Factory defined color
primaries, which ensure consistent color gamut from projector-to-projector, can be altered
in the Service menu only. If you suspect alteration, the factory settings can be recovered
with selection of Factory Defaults in the Service menu (password-protected).
COLOR TEMPERATURE — Adjust to apply a specific and accurate color temperature
to all displays. Color temperatures are expressed in degrees Kelvin (3200-9300K), and
utilize different combinations of the projector’s original native color primaries to produce
a “coloration” or cast (reddish or bluish) in images—the lower the temperature, the
more reddish the cast; the higher the temperature, the more bluish the cast. Note that
the slidebar is enabled only if you have a source connected and have selected “Color
Temperature” in the adjacent “Select Color Adjustment” pull-down list in the Advanced
Image Settings menu.
FRAME DELAY — Set the interval of delay desired between the input signal and its
appearance on screen. For applications such as simulation, where the feeling of “real
time” image response is a priority, a minimum setting is usually preferable. For projectors
capable of 3D (stereographic) applications where alternating left-right frames must be
synchronized with the corresponding L/R shutters in 3D glasses, a frame delay setting of
two (or multiple of two) may be more useful. Delay may vary between sources.
MOTION FILTER — This control is most useful for smoothing out moving images
from interlaced sources. In most cases the proper Motion Filter setting is automatically
determined according to the type of incoming source signal. However, if your source is
jittery and/or tearing you may wish to “force” a setting to ensure stable processing for this
source—if desired, override the default “Auto” setting by selecting the appropriate motion
filter:
1. AUTO: The projector will automatically use the correct motion filter according to
the incoming signal.
2. STILL: For static images with no motion, such as graphics from a CD.
3. MOTION: For video images that did not originate from film, or for moving
computer-generated images.
4. FILM: For video images that originated from film. This will optimize image quality
and stability.
FILM MODE THRESHOLD — This setting determines how sensitively the projector can
detect if an incoming video signal originated from film or not.
56
Section 3: Operation
DETAIL THRESHOLD — Use “Detail Threshold” to define at what frequency level the
“Detail” control will begin to magnify high frequencies, which adds details back into the
image. Raise the threshold to ignore more of these high frequencies, and lower the
threshold to magnify more of these frequencies. A setting of “0”, for example, means no
noise will be ignored and all will be magnified. An ideal detail threshold is one in which
high frequencies that are causing objectionable noise are not magnified when using
“Detail”, but frequencies which can help sharpen an overly-soft image are magnified
when using “Detail”.
Use the Configuration menu to
define general operating parameters

Image Orientation
Set the orientation of the image according to the orientation of your projector. If the
setting is incorrect, projected images will be reversed and/or upside down.
Fade Time
Set how long (in seconds) it takes to gradually dissolve one image into another for a
source switch.
Auto Power-up
Enter a checkmark to enable the projector to automatically power up after losing power
due to a power failure or due to unplugging the projector during operation. Runco
recommends that this be left unchecked, as a power loss in an unattended house will
result in the projector turning on without anyone realizing it is on.
Note that unsaved display adjustments may be lost.
Set Date & Time
Enter/read the current year-month-day and hour-minute-second. Changes here reset the

Section 3: Operation
Menu Preferences —
SUBMENU
Use the options in this submenu
to adjust the appearance, content
and/or location of on-screen menus
and messages.
LARGE MENU FONT — Enter a
checkmark to enlarge menus and
their text. You may have to adjust “Menu Location” to accommodate the increased menu
area.
MENU LOCATION — Use the pull-down list to choose a pre-defined default or customized
location for the display of all on-screen menus.
To create a custom menu location quickly, choose a preset that is closest to the desired
location. Then adjust “Horizontal Shift” and “Vertical Shift” slidebars to move the menu to
the desired location. Avoid locations too close to a corner or edge to prevent cropping of
larger menus.
HORIZONTAL SHIFT AND VERTICAL SHIFT — Shift your menus as desired, creating
a customized menu location.
DISPLAY CHANNEL LIST — Enter a checkmark if you want to see a scrollable channel
list whenever you press Channel from your presentation. Channels marked with a list
icon in the Channel Setup menu will appear here. The “Display Channel List” option also
enables on-screen feedback when using the Input key. If you prefer to hide the channel
list and input dialog box while switching channels and sources during a presentation, clear
the checkbox.
NOTE: The Channel List and input dialog box cannot be hidden during use of the
menus.
DISPLAY SLIDEBARS — Enter a checkmark to superimpose a small slidebar over the
current image whenever an adjustable parameter is selected directly with a key such
as Contrast or Bright . If “Display Slidebars” is unchecked, these slidebars can still be
accessed, but will be hidden during adjustment. This option does not affect slidebars in
menus.
DISPLAY ERROR MESSAGES — Choose in what way you want to be notified of errors
detected in either the incoming signal or projector. Select “Screen” or “All” to see a brief
on-screen message or select “RS232” to receive messages via RS232 (or RS422) serial
communication only. Select “Off” to hide error message displays. Since the DHD Controller
uses the RS-232 port, Runco recommends this be set to ‘screen’.
58
Section 3: Operation
Figure 3.14. Communications
Baud Rates
The baud rate setting determines the speed of communication to and from the projector
on the RS232 or RS422 links. The maximum rate for either standard is 115200. The default
baud rate for use with the DHD Controller is 115200. If this is changed, communication
with the DHD Controller will be lost.
Projector
Enter a three-digit number (such as “001”) to assign or change a number to the projector
currently in use. If the current projector already has a number assigned, that number will
appear here (for example, “004” in Figure 3.14, above). Numerical identity for projectors
enables you to communicate with a single projector within a multiple-projector application
(see also Proj key in 3.2, Using the Keypads). If you make a mistake in assigning or
changing the projector number, press Exit to cancel.
NOTE: This feature is not used when the projector is used with the DHD Controller.
Network Routing
NOTE: 1) Not applicable for stand-alone projectors or simple serial networks with only
one type of controller and linking.
SEPARATE: Select “Separate” (factory default) to keep RS232, RS422 and Ethernet
messages on their respective paths instead of being broadcast to the other types of
ports. In Figure 3.15A, RS422 controls only the projector to which it is connected. In
Figure 3.15B, either RS232 or RS422 will control the network.
NOTE: This feature is not used when the projector is used with the DHD Controller.

Backlight
Toggle the built-in keypad lighting on/off.
Front IR / Back IR
As needed for your application, set to “on” so that the front and/or rear IR sensor locations
on the projector responds to the IR keypad. Set to “off” to disable.
To disable both IR sensors, you cannot use the IR remote keypad to select the second
OFF setting. This safeguard prevents accidentally disabling an IR keypad while you are
using it. Instead, use either the built-in keypad or a wired remote (optional) to set the
remaining active sensor to OFF. The projector will no longer respond to an IR remote
keypad.
Wired Keypad
Select “On” to enable use of a wired remote keypad connected to the rear of the projector.
The projector will then respond to incoming commands from either port. To disable the
wired keypad, you must use a different keypad—the built-in or an IR remote keypad—to
select “off”. This safeguard prevents you from accidentally disabling the wired keypad
during use.

necessary, as it may cause some artifacting in the image.
Brightness Uniformity — SUBMENU
Brightness Uniformity provides further refinement of displays already matched for
their primary colors and overall light output. Use Brightness Uniformity to create an
exceptionally smooth image in which no area appears brighter and/or more red, green
or blue than another. In the Brightness Uniformity menu, enable the “Uniformity Enable”
checkbox (enter a checkmark) to access a multitude of adjustments for critical color light
output control in specific areas throughout the image. Your settings apply as long as the
“Uniformity Enable” checkbox is enabled and you are using a “User” color temperature

Color Adjustments by X/Y, and Color Saturation — SUBMENUS
NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color performance or “gamut”.
Sometimes known as Comprehensive Color Adjustment™. 2) Factory-measured primary
color levels, which ensure a specific color performance from projector-to-projector, can
be altered in the Service menu only. If you suspect alteration of these defaults, the factory
settings can be recovered with selection of “ Factory Defaults” in the Color Primary Settings
submenu accessed via the Service menu (password-protected).
From the factory, the projector can utilize
any of the 3 pre-defined color performance
settings identified at right (default=Max
Drives) or colors can be driven on the basis
of color temperature. For most applications,
one of these options will produce accurate
and realistic colors from a variety of sources.
They can be applied at any time in the
Advanced Image Settings menu (“Select
Color Adjustment”) and are not adjustable.
DEFINING “USER” COLOR GAMUTS: In some cases, you may find that none of the
predefined “Select Color Adjustment” options exactly suit your needs. For example, you
may require a unique color gamut (range) for a single projector or application, or you may
need to precisely match colors across multiple adjacent displays. In such cases, use
either the Color Adjustments by X,Y or Color Saturation submenu to define the precise
hue of each primary color component (red, green, blue, and white) used to generate the
millions of colors produced in displays. You can create up to four custom color gamuts
(User 1, 2, 3, or 4) defined by these adjustments.
Note that the two menus differ only in their user interface, so use whichever menu best
suits your needs and application.
• Color Adjustments by X,Y — Enter known x/y coordinates from the chromaticity
graph. For best results, use with a color meter.
• Color Saturation — Adjust color slidebars and judge image color by eye. A color
meter can also be used.
A user-defined color “adjustment” can be applied by selecting it in the Advanced Image
Settings menu (“Select Color Adjustment”).
NOTE: Defining a “User” color gamut when a test pattern is displayed does not get saved
in the current channel. Display the source first then select a color gamut (User) from Select
Color Adjustment. Changes here are then saved for that source in channel memory.
62
Section 3: Operation
COLOR ADJUSTMENT BY X,Y:
Use this submenu if you want to
alter, add or copy a color gamut (i.e.,
“color adjustment”). Controls in this
menu define the precise hue of each
primary color component (red, green,
blue, and white) used to generate
the millions of colors produced in
displays. The x/y coordinates for
each color define its location on the
standard CIE chromaticity graph
(see Figure 3.19)—changing either
or both of these numbers will change
the hue of the color, and relocate
the “triangle” for possible colors. For
example, changing the x/y coordinates for red will either move the color closer to orange
or closer to violet, which will in turn affect all displayed colors having a red component.
Adjust the slidebars or enter new specific coordinates as desired to define or change up
to four “User” color gamuts needed for your environment and applications. Apply the
new “User” color gamuts at any time in the Advanced Image Settings menu.
Figure 3.19. CIE 1931 Chromaticity Diagram
NOTE: Keep new x,y coordinates within the original color gamut triangle shown here.
See Section 6 – Specification for color primaries.
63
Section 3: Operation
COLOR SATURATION: Use this
submenu if you do not have specific
color coordinates in mind and will
simply judge color performance
by eye (or meter). Like the Color
Adjustment by X,Y submenu, each
color control actually defines new
x/y coordinates for that color and
changes its hue — it is just a different
interface.
Adjust the hue of each primary color
(red, green, blue, and white) by using
more or less of it in relation to the
other colors.
Figure 3.20. Customize Color
NOTE: A Color Saturation adjustment sets the corresponding x/y coordinates shown in
the Color Adjustment by X,Y submenu. These x/y coordinates will remain stable for this
User gamut until they are changed again via either menu. Values displayed in the Color
Saturation menu, however, will likely fluctuate as you use the projector, and will be different
when you return to this menu at some point in the future. These floating changes do not
affect the x/y coordinates or gamut.
System Configuration ➤
DIAGNOSTICS / CALIBRATION
Test Pattern
Choose the desired internal test
pattern to display or select OFF to
turn off a test pattern. Alternatively,
use the Test key for cycling through
test patterns.
NOTE: Runco recommends that all
calibration parameters (grey scale,
sizing, etc.) be done with external
test patterns.
Test Pattern Grey Level
Set the desired level of grey for displaying in the full gray field test pattern.
Freeze Image
Enter a check mark to freeze (stop) an image on a single frame. This diagnostic tool is
useful if you need to examine in detail a still version of an incoming image that cannot be
“frozen” at the source. For example, in moving images it is sometimes difficult to observe
artifacts such as external deinterlacing/resizing and signal noise. Remove the checkmark
to return back to normal.
64
Section 3: Operation
Color Enable
Select which color or colors you want to see. This is useful while working with color
temperature, input levels or other special setup parameters.
Odd Pixel Adjustment
NOTES: Factory-set and rarely required by user.
When using certain RGB sources, you may need to adjust the normal gain or offset
of odd pixels in relation to even pixels. This will smooth out very narrow (1-pixel wide)
“checks” or vertical stripes that indicate adjacent “on” and “off” pixels. Although offset
and gain slidebars can be adjusted individually and manually, using the Level Detector
simplifies this process (see Figure 3.21):
1. Use an external analog native-sized continuous grayscale test pattern with at
least 256-levels.
2. Turn “Level Detector” on.
3. Set “Level Value” to ~200. The image should now be black-and-white (or blackand-one color, if you use “Color Enable” function).
4. Adjust offset. Half of the pixels will move, the other half will not.
5. Adjust until the two transition regions overlap. The stripe of noise will be minimized,
defined by the value in the slidebar.
6. Set “Level Value” to ~800. The image should now be black-and-white.
7. Repeat Steps 4 and 5, but adjusting gain.
8. Repeat Steps 3-7 for all remaining colors. Your RGB source should now be
OK.
Figure 3.21. Using “Odd Pixel Adjustment”
NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 represents
no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment eliminates “1 pixel
on, 1 pixel off” patterns only, not any type of larger patterns.
65
Section 3: Operation
Reserved
No function.
Peak Detector
The “Peak Detector” is fast method of defining individual input levels, and can improve
the accuracy of input levels set by the Auto Input Level function. Enabling the “Peak
Detector” activates a special operating mode for detecting only pixels that are considered
black or white — all other levels are displayed as a mid-level gray. When used with a
16-step grayscale pattern in which the two black and white bands are known to be at
opposite edges of the image, you can watch these isolated areas while adjusting individual
blacklevels and input drives until both bands are just visible. Images from this source will
then display correct blacks and whites without crushing or washing out.
Level Detector
The “Level Detector” checkbox enables a specific thresholds for blacks and whites — input
levels that fall below a specified Level Value (see below) are displayed as black, and all
others are displayed as white. It aids in Odd Pixel Adjustment. To use:
1. Enable “Level Detector” and display a continuous grayscale.
2. Set “Level Value” to near black (such as 200).
3. Adjust Offsets to minimize area of black stripe.
4. Set “Level Value” to near white (such as 800).
5. Adjust Gains to minimize area of white stripe.
Level Value
The “Level Value” defines the value to be used by the Level Detector in recognizing blacks
and whites. See Level Detector, above.
3.7 Working with the
Lamp
Whenever you install a new lamp in the
projector, access the Lamp menu to record
the lamp serial number in the projector’s
memory. You can also choose a lamp mode
for regulating power and light output, change
optical aperture size, and access other readonly information pertaining to past and present
lamps.
LAMP HOURS shows the number of hours logged on the current lamp. Whenever you
record a new lamp serial number this value automatically resets to “0”, where it begins to
log time for the new lamp.
NOTE: Read-only. This information also appears in the Status menu.
LAMP S/N is the serial number recorded for the current lamp. When you install a new
lamp and enter its serial number, the number will appear here. NOTE: Read-only.
66
Section 3: Operation
Enter a checkmark for LAMP MESSAGE to enable a warning message that will appear
upon power-up when the lamp has reached the specified lamp limit and should be
replaced. Delete the checkmark to prevent display of this message—instead, when your
lamp expires, only the status display messages on the back of the projector will provide
the visual warning to replace the lamp.
NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled.
2) When a lamp warning message appears, press Exit to temporarily cancel the message.
The message will continue to appear upon power-up until you install a new lamp.
Set LAMP LIMIT to the number of hours you expect to log on the current lamp before
replacing it. This will trigger a lamp message on-screen (if enabled).
NOTES: 1) If you change modes over the life of a lamp, the lamp limit you originally
expected may no longer be possible. 2) Turning the lamp on and off reduces lamp life
significantly, as do other factors. 3) It is recommended that Lamp Limit not exceed the
expected lamp life, otherwise a lamp could become dangerously fragile with overuse.
Set which LAMP MODE you want to use in order to control the
light output. You can choose to run the lamp as bright as possible
(i.e., always using maximum power—this is the default upon
power up) or you can power the lamp with a specific wattage
appropriate for the installed lamp or you can set a specific
intensity (brightness) to maintain. Although there are exceptions,
generally higher light output or higher power settings can shorten
lamp life.
Figure 3.22.
Use the lamp mode that best suits your brightness needs. For example, in a tiled application
you may want to precisely match brightness levels between adjacent images—judge by
eye and set each individual Lamp Power setting as necessary. Or if you want images
to be as bright as possible—choose Max Brightness. Always keep in mind that higher
lamp power settings can shorten lamp life.
Lamp modes are described below:
• Max Brightness: The lamp will always burn as brightly as possible, driven by
100% of the power level rating for the installed lamp (see Section 6, Specifications).
Keep in mind that the “maximum brightness” for any lamp gradually diminishes
with age — images will become dimmer over time. Its current output level appears
in the “Intensity” option (note: not in lumens).
• Intensity: Brightness will remain close to a specified level for as long as possible.
Once you select this option, enter a number representing the intensity level
(brightness) you wish to maintain—the projector will automatically adjust power
as needed to maintain this intensity as closely as possible. Note that the intensity
value is a correlation only and does not represent an actual lumens level. See
“Intensity” on the next page.
• Power: The power supplied to the lamp will remain at your specified wattage
level. Once you select this option, enter the number of watts representing the
power level you wish to maintain. See “Power” on the next page.
67
Section 3: Operation
POWER – This slidebar and number indicates how many
watts are applied to the lamp. You can apply anywhere
from approximately 60-65% of the maximum power intended for the installed lamp up to
100% of the lamp rating. Set for the number of watts as desired, keeping in mind that
lower power levels produce dimmer images. When in either Power or Max Brightness
modes, the power level remains constant. Specifying a maximum power level here is the
same as operating in Max Brightness mode.
NOTES: Power level can be set only if the lamp is in Power mode.
INTENSITY – This value and slidebar represents the
current brightness of your lamp, decreasing over time
when you are operating in Max Brightness mode or at a specific Power level. When
you are operating in “Intensity” mode this value remains at the original “Intensity” setting
chosen and cannot be adjusted.
NOTE: The number shown for “intensity” is not the actual lumen output, but rather a
correlated value only—1246 may represent 3500 lumens, for example.
To use “Intensity” mode, judge by eye (or use a meter) and set the level as desired for
your application. Over time, the projector will automatically increase the power supplied to
the lamp as needed to maintain the chosen intensity as closely as possible.
HOW LONG CAN I MAINTAIN BRIGHTNESS? Software can maintain your “Intensity”
setting until the required power reaches the maximum rating for the lamp. The lower the
setting, the longer it will take to reach this threshold and the longer you can maintain
the desired brightness. Keep in mind that once the lamp power reaches its maximum
wattage (see “Power”, above), this tracking is no longer possible. At this point, the lamp
will gradually begin to dim as usual, even though your original “Intensity” value will still
appear in the menu. To resume accurate tracking, reduce the intensity setting so that the
resulting “Power” value is less than its maximum—the lower the intensity, the longer it
can be maintained.
For example, a 1000 watt lamp can be driven at no more than 1000 watts. To produce
desired brightness at the screen, a new lamp would likely need less than this maximum
rating — perhaps 812 watts (example only). Over time, however, the lamp will require more
and more current in order to generate the desired light, until eventually the lamp wattage
reaches its 1000-watt maximum and the lamp power automatically levels off. At this point,
the tracking function terminates (i.e., the power level stabilizes) and the lamp will begin to
dim normally. Either reduce your “Intensity” setting or replace the lamp.
Do not lower the “Intensity” so much that the corresponding “Power” value reaches
its minimum—the intensity setting will be inaccurate and cannot be maintained. For best
results in achieving uniform intensity amongst tiled images, choose an “Intensity” setting
that enables all lamps to operate at less than the maximum number of watts available in
your projector but high enough to keep the corresponding lamp power above its minimum.
See “Power”, above.
NOTES: 1) Lamps become more stable over time, thus a specific intensity is more easily
maintained as the lamp ages. 2) Intensity can be set only if the lamp is in “Intensity” mode
3) Intensity cannot exceed the output of Max Brightness mode.
68
Section 3: Operation
OPTICAL APERTURE – The optical aperture
inside the projector controls the diameter of the
light beam passing through the system. With a
fully open aperture (slidebar default of “0”), the
maximum amount of light passes through for
maximum brightness in your images. Increase the slidebar setting to reduce the aperture
diameter and maximize contrast ratio instead.
LAMP HISTORY – This read-only option lists the lamps most recently installed and
recorded in the projector. Lamp History automatically updates whenever
you record a new lamp serial number—the new lamp is added to the
bottom of the list.
Use CHANGE LAMP to record the serial number for a newly installed lamp:
In the Lamp S/N window, use the number text entry keys to record the new lamp serial
number and press again to accept the change. See Using Slidebars and Other Controls
if you need help entering the number. Once entered, the new lamp serial number will be
added to the Lamp History menu and the Lamp Hours timer will reset to “0”. Lamp Mode
and Lamp Limit remain as they were for the previous lamp and can be changed at any
time.
Figure 3.23. Recording the New Lamp Serial Number
NOTE: Enter a serial number only if you have just installed a new lamp. This will help
ensure that lamp timer is not reset on an old lamp and that the number of hours logged
on the lamp will be accurate.
IMPORTANT
Always record the serial number of a NEW lamp.
69
Section 3: Operation
How Old is My Lamp? ➤
When a new lamp is installed and its serial
number recorded by selecting “Change
Lamp” in the Lamp menu, the lamp timer
resets to “0” and begins logging time for
the new lamp. This tally appears in both
the Lamp menu (see right) and the Status
menu.
To review the number of hours logged for
previous lamps, consult the Lamp History
menu.
When to Replace ➤
the Lamp
If the “Lamp Message” checkbox has been enabled in the Lamp menu (recommended),
an expiry message will appear upon power-up when the lamp has reached its defined
“Lamp Limit”. The lamp should be replaced.
The “Lamp Limit” setting should not exceed the expected lamp life, as an old lamp
becomes increasingly fragile and more prone to sudden failure. See also 4.4, Lamp
Replacement.
3.8 Status Menu
The read-only Status menu lists a variety of details about the standard and optional
components currently detected in the projector. Refer to the Status menu for versions
of hardware and software installed, the type (size) of lamp, the hours logged in total and
for a specific period (such as a rental period), and for your projector model name and
serial number. In addition, the Status menu identifies the current channel, its location, its
frequencies and other details.

User Errors
➤
Invalid User Entry
A keypad entry not recognized by the projector triggers a short on-screen error message
identifying the problem. For example, if you specify a channel number that is not available,
the message “Invalid Channel” will appear. Or if you try to enter the wrong password,
you’ll see “Invalid Password”. Press or Exit to clear the message and try again.
Input Signal Errors
NOTE: On-screen display of “Invalid User Entry” messages cannot be disabled, even if
Display Error Messages has been set to “Off”.
An input signal error message occurs if you are in presentation level (i.e., there are no
menus present) and have selected an input on which the projector detects a problem.
While menus remain operational and any key press will temporarily remove any displayed
error message, you must resolve the signal problem in order to permanently eliminate
the message.
No Signal
The message “No signal” occurs when there is no source signal detected at the selected
input—both HSYNC and VSYNC are inactive and the screen background is black.
Connect or correct the signal, or try another input.
Bad Sync
The message “Bad Sync” occurs when HSYNC or VSYNC are active but the signal
cannot be displayed. Such a condition occurs when only one of the two sync signals
is present or when either sync signal is unstable or of the wrong frequency. Correct the
signal or select another input.
71
Section 3: Operation
Other Signal Error Messages
In addition to the common “Bad Sync” and “No Signal” errors, you may encounter a signal
error message indicating that HSYNC and/or VSYNC are either too fast or too slow. When
such a message appears, check the frequencies shown in the Status menu. If they are
correct, then the signal is not recognized by the projector. On some PCs you may be able
to change the settings to generate a compatible signal. If the frequencies shown in the
Status menu are incorrect, check the cabling to see where the problem might originate.
When the projector encounters a system malfunction, either a System Warning message
or a System Error message may appear. Both types of messages are accompanied by a
numerical error code on the status LED display. A system malfunction can be cleared with
Exit from presentation level, but may indicate the need for service by a qualified service
technician.
NOTE: System messages appear on-screen only if Display Error Messages has been set
to “Screen” or “All”.
System Warnings
A system warning indicates that a system malfunction has been detected (see Status
LED Codes, below). A system warning message replaces any input signal message
and disappears when the input signal status changes. While the projector will remain
operational, the message indicates the presence of a potentially serious problem that
should be investigated. You can press Exit to remove the message, but for best results
you should reset the projector—power the projector down and up again with the (power)
key.
System Errors
A system error message indicates that a serious malfunction has been detected and must
be investigated as soon as possible (see Status LED Codes, below). The projector will
no longer operate and must be reset—power the projector down and up again with the
(power) key.
The Status LED Codes
If the status code display on the back of the projector shows one of the following values,
you have encountered a likely system error requiring the attention of a qualified service
technician (see System Warnings and System Errors, above). Acknowledge and clear
the error with Exit from presentation level, or try resetting the projector by powering it off
and on again, cooling when necessary. Consult Table 3.5 and contact your dealer if the
problem persists.
The specific code number identifies the source of the error detected, and is particularly useful
in cases where the projector is far away. For example, the code “27” means the lamp could
not be turned on. Error codes for this projector are listed in Table 3.5.

cart combination should be used with care. Sudden stops, excessive force and
uneven surfaces may cause the projector and cart combination to overturn.
• Only use Runco-approved ceiling mount fixture, if the projector is to be ceiling
mounted.
74
Section 4: Maintenance
Lamp: The projector uses a Cermax® Xenon lamp to deliver its high brightness. A lamp
should be replaced when it has reached its end of life (1000 hrs, typical) or if a noticeable
change in brightness or excessive lamp flicker occurs. Keep track of the number of hours
the lamp has been in use (Lamp Menu) and be aware of any changes to brightness.
These indicators will help you effectively maintain operation of the projector.
WARNING
Wait approximately 5 minutes after powering down
the projector to allow internal cooling fans to stop and for
the lamp to cool sufficiently before removing.
The lamp is under great pressure when hot and may explode causing
physical injury and/or property damage. Allow a lamp to cool before
handling or unplugging the projector.
WARNING
Use lamps of the correct wattage for your projector model
when replacing.
Use only lamps supplied by Runco.
Refer to 4.4 Lamp Replacement for instructions.
Use only the attachments and/or accessories recommended by Runco. Use of others
may result in the risk of fire, shock or personal injury.
WARNING
Use only the AC power cord supplied. Do not attempt operation if the
AC supply is not within the specified voltage and power range.
Refer to the Specifications in Section 6.
• Do not set or rest items on the power cord. Place the projector in an area where
the projector cord cannot be abused or damaged by persons walking on it or by
objects rolling over it.
• Operate the projector at the specified voltage only. Do not overload power outlets
and extension cords as this can result in fire or shock hazards.
• The projector is equipped with a three-wire plug having a third grounding pin. This
is a safety feature – if you are unable to insert the plug into an outlet contact an
electrician to have the outlet replaced. Do not defeat the safety purpose of this
grounding-type plug.
75
Section 4: Maintenance
Ventilation ➤
Slots and vents in the projector provide ventilation. Never block or cover these openings.
This ensures reliable operation of the projector and prevents overheating.
• Do not place the projector over a radiator or heat register. The projector should not
be placed in an enclosure unless proper ventilation is provided.
• Do not insert objects into the ventilation openings of the projector. They may
touch dangerous voltages or short-out components resulting in a fire or shock
hazard. Do not spill liquids of any kind into the projector. Should an accidental spill
occur, immediately unplug the projector and have it serviced by a qualified service
technician.
Servicing ➤
If any of the following conditions exist, immediately unplug the projector from the power
outlet and ask a qualified service technician to look at it.
• The power cord has been damaged.
• The internal cooling fans do not turn on within two minutes when the projector is
first powered up.
• Liquid has been spilled into the projector.
• The projector has been exposed to excessive moisture.

Lens
As required
CLEAN: Clean if absolutely necessary. A small
amount of dust on the lens has very little affect
on picture quality.
To clean: Apply a solvent such as acetone,
alcohol or vinegar sparingly to clean, lint-free
lens tissue. Wipe across the surface of the lens.
Do not scrub or rub tissue in circular motion, this
will scratch the lens. Do not reuse tissue. Do not
use cleaning tools treated with Ether. If particles
still appear on the lens, try using compressed air
to remove.
Lamp
CLEAN: Clean if absolutely necessary. Never
touch the glass surface of the lamp. Fingerprints
left on the glass will seriously degrade lamp
performance or cause “hotspots” which can
lead to an accumulation of intense heat in the
touched area and cause the lamp to shatter.
As required
To clean: Wait until lamp is cool. Moisten a
clean, lint-free cotton cloth with isopropyl alcohol
and gently rub the surface of the glass in a
circular motion until clean.

SECTION 5
Troubleshooting
If the projector does not appear to be operating properly, note the symptoms present
and use the following guide to assist you. If you cannot resolve the problems yourself,
contact your dealer for assistance.
NOTE: A qualified Runco service technician is required when opening the projector
to diagnose any “probable cause”.
SYMPTOM
The projector is on but
there’s no display...
CAUSE/REMEDY
Was a lens cover accidentally left on? Remove lens
cover.
Make sure the shutter is OPEN.
Is the lamp ignited? Check for interlock problems such
as an open lamp door OR check for light spillage out the
back.
Is the correct input selected? Check cable connections.
Check if menus appear on screen.
Can you access test patterns? Make sure there is not a
full black test pattern selected for display—press Menu
to access test patterns, then cycle patterns with keys.
Check your source connections again.
Severe motion

screen
The display is jittery or
unstable...
If the display is jittery or blinking erratically, ensure that
the source is properly connected and of adequate
quality for detection. With a poor quality or improperly
connected source, the projector will repeatedly attempt
to display an image, however briefly.
The horizontal or vertical scan frequency of the input
signal may be out of range for the projector. Refer to
Section 6, Specifications for scan frequency ranges.
The sync signal may be inadequate. Correct the source
problem.
The display is faint...
Brightness and/or contrast and/or gamma may be set
incorrectly.
The source may be double terminated. Ensure the
source is terminated only once.
The source (if non-video) may need a different sync tip
clamp location.
The upper portion of
the display is waving,
tearing or jittering...
This can sometimes occur with video or VCR sources.
Check your source.

It’s possible that excessive voltage noise on the AC or
ground input has interrupted the projector’s ability to lock
on to a signal. Power down the projector and disconnect
from AC. Then plug in again and power up as usual.
Colors in the display
are inaccurate...
Try Auto Setup.
If incoming data is still missing from the image, reduce
the image size to within the display area available in the
projector.
The color, tint, color space, color temperature and/or
other settings may require adjustment.
Ensure signal connections are correct.
Make sure you are using the proper channel for this
source.
Values in Color
Saturation slidebars
vary over time...
Once defined, Color Saturation slidebar values fluctuate
over time and will likely be different upon subsequent
visits to this menu. This is normal and should be ignored,
as these changes do not redefine the x/y coordinates or
color gamut.
The display is not
rectangular...
Check leveling of the projector. Make sure that the lens
surface and screen are as parallel to each other as
possible.
The display is
“noisy”...
Display adjustment at your input source may be required.
The video input may not be terminated. Make sure the
video input is terminated (75Ω). If it is the last connection in
a loop-through chain, the video input should be terminated
at the last source input only.
The input signal and/or signal cables carrying the input
signal may be of poor quality.
If the distance between the input source device and the
projector is greater than 75 feet, signal amplification/
conditioning may be required.
If the source is a VCR or off-air broadcast, detail may be
set too high.
84
Section 5: Troubleshooting
SYMPTOM
Lamp does not ignite
CAUSE/REMEDY
If the lamp won’t ignite, there may be an interlock failure
such as an open lamp door, or failed lamp fan. An error
code will display on the status LED display located on the
built in keypad.
If a temperature is too high (e.g.“DMD over critical temp
limit”), the lamp will not ignite until the temperature is low
enough. Cool the projector and try again.
If the lamp does not ignite after a second and third try,
replace the lamp.

brightness, tint, blanking, size, offsets, and others.
Dot Clock ➤
The maximum frequency of the pixel clock. Also known as pixel clock rate.
E-EDID ➤
The Enhanced Extended Display Identification Data standard, established by VESA,
enables properties (such as resolution) of a display device to be detected by the display
card in a controlling device such as a PC. The PC, in turn, can then output in a matching
format to fill the display. Some sources used with the projector are VESA EEDID reported.
Flicker ➤
A very rapid variation in image brightness caused by a frame rate that is too slow. (See
Interlace) See also Lamp Flicker.
Foot-Candle ➤
Foot-Lambert ➤

Help Text ➤
The intensity of visible light per square foot.
The luminance (brightness) which results from one foot-candle of illumination falling on a
perfectly diffuse surface.
The frequency at which complete images are generated. For non-interlaced signals, the
frame rate is identical to the vertical frequency. For interlaced signals, the frame rate (also
known as field rate) is one half of vertical frequency.
The ability of a screen to direct incident light to an audience. A flat matte white wall has
a gain of approximately 1. Screens with gain less than 1 attenuate incident light; screens
with gain more than 1 direct more incident light to the audience but have a narrow viewing
angle. For example: An image reflecting off a 10 gain screen appears 10 times brighter
than it would if reflected off a matte white wall. Curved screens usually have larger gain
than flat screens.

Input ➤
Input Signal ➤
The frequency at which scan lines are generated, which varies amongst sources. Also
called horizontal scan rate or line rate.
The difference between the center of the projected image and the center of the projector
lens. For clarity, offset is often expressed as the maximum amount of the image that can
be projected to one side of the lens center without degrading the image quality. Horizontal
offset ranges can be affected by the type of lens in use, and whether or not the image is
offset vertically at the same time.
A circular area of a screen where the image appears brighter than elsewhere on the
screen. A hot spot appears along the line of sight and “moves” with the line of sight. High
gain screens and rear screens designed for slide or movie projection usually have a hot
spot.
A physical connection route for a source signal, described by a 2-digit number
representing 1) its switcher/projector location and 2) its slot in the switcher/projector.
Signal sent from a source device to the projector.
Interface ➤
A device, such as the Serial Digital Input Module, that accepts an input signal for display
by the projector.
Interlace ➤
A method used by video tape players and some computers to double the vertical
resolution without increasing the horizontal line rate. If the resulting frame/field rate is too
low, the image may flicker depending on the image content.
Keypad ➤
A small push-button device for controlling most projector settings and operation. For more
information, refer to 3.3, Using the Keypad.
Keystone ➤
A distortion of the image which occurs when the top and bottom borders of the image
are unequal in length. Side borders both slant in or out, producing a “keyhole” shaped
image. It is caused when the screen and lens surface are not parallel, or by poor Keystone
adjustment.
Lamp Flicker ➤
As the lamp ages, the shape of two anodes may change from two points to a flattened
state. When this occurs, the arc jumps across the gap from varying points. This is seen as
image flicker. Turning the Lamp Conditioning feature ON will pulse the lamp and gradually
“condition” the two anodes back to two points. Lamp Conditioning may take seconds,
minutes or hours to reach full effectiveness. NOTE: Lamp flicker can occur at any time in
the lamps life. The length of time, over which flicker may occur varies considerably and
unpredictably. This behavior is inherent in UHP lamps.
Linearity ➤
The reproduction of the horizontal and vertical size of characters and/or shapes over the
entire screen.
Line of Best Viewing ➤
When light from a projector is incident on a screen, the light reflects from the screen such
that the angle of reflection equals the angle of incidence. The Line of Best Viewing is along
the line of reflection.
Loopthrough (Loopthru) ➤
The method of feeding a series of high impedance inputs from a single video source with a
coaxial transmission line in such a manner that the line is terminated with its characteristic
impedance at the last input on the line.
Lumen ➤
Luminance ➤
Lux ➤
The unit of measure for the amount of visible light emitted by a light source.
The signal representing the measurable intensity (comparable to brightness) of an
electronic image when the image is represented as separate chrominance and luminance.
Luminance also expresses the light intensity of a diffuse source as a function of its area;
measured in lumens or candles per square foot (1 lumen per square foot = 1 foot-lambert).
SMPTE RP 98 calls for a luminance of 12 to 22 foot-lamberts for theatre screens. See:
Foot-lambert.
The amount of visible light per square meter incident on a surface. 1 lux = 1 lumen/square
meter = 0.093 foot-candles

Throw Distance
Calculating Throw Distance
It is important throw distance be precisely calculated for your installation using the
appropriate formula from the chart below. To calculate throw distance you must know the
screen size and the lens type installed in the projector. In general, the larger you want the
image to be the greater the distance you must allow between the lens and the screen.
NOTES: 1) Throw distance is
measured from the screen to
the center of the projector’s
lens. 2) This measurement is not
necessarily parallel to the floor as
the projector and screen may be
inclined.
Throw Distance (TD) is measured from the
screen to the center of the projector’s lens.
