About Monitor Sensing
AppleÕs Monitor Sensing speciÞcation allows graphics
cards to identify the attached monitor. During startup, the
XCLAIM VR checks the status of three of the Þfteen pins
on the Apple monitor port. It then auto-conÞgures itself
according to the monitor sense code detected and enables
all resolutions supported by the monitor. Since the
XCLAIM VR relies on this sense code to correctly autoconÞgure during startup, the monitor must supply the
appropriate sense code.
In a case where your monitor does not directly supply the
sense code information, an adapter can be used to set the
appropriate sense code for your monitor. Typically, an
adapter is used to connect a VGA monitor to the Apple
monitor port, or to simply supply the correct monitor
sense code information.
If the adapter supplies the sense code information for
only one resolution, then that resolution will be the only
one available, even if the monitor supports multiple
resolutions. Therefore, when using an adapter to supply
the sense code, it must be designed to supply the proper
code for the monitor you are using it with; otherwise, the
XCLAIM VR cannot correctly auto-conÞgure itself for the
attached monitor.
Although the XCLAIM VR card does not output Sync-onGreen (SOG) signals directly, adapters are available that
can overlay the Composite Synchronization Signal and
send it through the Green video signal line so that you can
use an SOG monitor. Monitors requiring an SOG signal
usually have only three BNC connectors (RGB).
For more information about obtaining a sense code or
synchronization signal adapter, contact ATI Customer
Support or ask your dealer. For information about how to
contact ATI Customer Support, select the Support button
on the ATI Displays Control panel.

Viewing 3D Graphics
XCLAIM VRÕs QuickDraw 3D Acceleration supports the
following advanced 3D graphics capabilities:
¥
QuickDraw 3D RAVE Support
¥
Six perspectively correct texture mapping functions
¥
16-bit z-buffering (a process that removes hidden
surfaces)
¥
Flat and Gouraud shading
¥
Alpha blending and fog effects
¥
Video texture and texture lighting
These features make it possible to quickly render 3D
graphics, produce atmospheric effects, calculate light and
color shading, and determine which objects are in the
foreground and which are in the background.
XCLAIM VR only displays 3D graphics in thousands and
millions of colors. 3D acceleration is not supported when
your color depth is 256 colors because there are too few
colors to display complex 3D textures. To change your
color depth, use the control strip, ATI Popup Menu, or the
Monitors & Sound control panel.
You can use the 3D Memory Monitor to see how memory
on your XCLAIM VR is allocated when displaying 3D
graphics. This will allow you to optimize 3D
performance. You can also adjust the compression of
textures using the 3D Texture Compression feature.
3D Texture Compression
You can adjust the 3D texture compression using the 3D
features included with XCLAIM VR. Some 3D textures
demand a signiÞcant amount of memory. To free up some
memory you can use 3D texture compression.
Page 20
Adjusting Texture Compression
When running 3D graphics, 3D textures are loaded into
the memory on your XCLAIM VR card. You can adjust the
texture compression to compress the 3D textures in
memory. Compressed textures take up less space so that
more textures can be loaded.
C
ha
ng
e
If you set your texture compression to None, you will get
the best image quality but your 3D textures may take up a
lot of memory.
Medium texture compression will compress your 32-bit
textures to 16-bit, thus reducing the memory required by
a texture in half.
High compression will compress your 32- and 16-bit
textures to 8-bit. High texture compression will save the
most memory but the loss in data may affect the image
quality.
3D Memory Monitor
XCLAIM VR supports advanced 3D features including
MIP maps, gouraud shading, fog effects, and texture
mapping. The 3D Memory Monitor shows how available
memory in the video card is allocated when displaying
3D graphics.
Page 21
Using the 3D Memory Monitor
When you open 3D graphics on your Mac, run the 3D
Memory Monitor to see how your XCLAIM VR has
allocated 3D memory.
To open the 3D Memory Monitor
1.
Select Control Panels from the Apple Menu.
2.
Select ATI Displays.
3.
Click on the 3D Memory icon.
When you open a 3D application window, you can see how
the additional memory required for 3D graphics is
allocated.
The 3D Memory Monitor shows you how the memory on
your XCLAIM VR has been allocated between display,
textures, and buffers. If you use up all XCLAIM VRÕs
available memory, your computer drops 3D textures and
substitute Gouraud shading.
Display
Screen indicates the amount of graphics memory
allocated to the displayÕs resolution and color depth.
Desktop Pattern indicates the amount of memory used by
your desktop pattern.
Page 22
To reduce the memory allocated to Display memory:
¥
change the color depth from millions to thousands
¥
decrease your screen resolution
Textures
Texture indicates the number and size of texture maps
loaded by 3D applications to add realism to 3D models
and environments. Bitmap indicates the memory
allocated to non-3D elements like 2D and video.
To reduce the memory allocated to Texture memory:
¥
reduce the amount of textures in your 3D graphic
¥
adjust 3D texture compression (See ÒAdjusting
Texture CompressionÓ on page 21.)
Buffers
Back Buffer and Z Buffer are directly related to the size of
the 3D window.
To reduce the memory allocated to Buffer memory:
¥
reduce the size of the display window containing
3D graphics
¥
reduce the number of the display windows
containing 3D graphics
Page 23
3D Quality
Texture mapping helps provide realistic quality images
by placing photo-realistic images or textures on a 3D
object. When these textured objects appear in the High
Quality setting, additional texture Þltering, or blending
takes place. In some applications or games, this additional
texture Þltering may not be desirable. For this reason, ATI
provides the 3D quality option to toggle the 3D texture
Þltering routines off and on.
You should experiment with this setting to get the best
quality and performance from your application or game.
Selection:
¥
High - Additional 3D texture Þltering is enabled
providing a premium rendering mode.
¥
Standard - Provides standard texture Þltering.
The default setting for 3D Quality is High.
NOTE
Page 24
3D Sync
Your XCLAIM VR graphics accelerator provides superior
3D performance by performing many tasks in offscreen
memory including graphic rendering. Depending on the
3D scene, the refresh rate of your computer monitor, and
the game or application, you may notice some slight
horizontal ßickering or ÒtearingÓ. This ßicker is caused by
the different rates at which the display performs a
complete screen redraw, and when the XCLAIM VR
moves images located in offscreen memory to the display
buffer. Synchronizing the redraw and the write to the
display buffer provides a ßicker-free 3D window.
¥
On (Synchronize with vertical refresh) - Provides a
ßicker-free 3D window. The display is synchronized
with the vertical refresh, so there isnÕt any ßickering
or ÒtearingÓ in the 3D window.
¥
Off (Do not synchronize with vertical refresh) Provides a boost in performance, but in some games
and applications it can introduce ßickering or
ÒtearingÓ in the 3D window.
You should experiment with these settings to Þnd the
proper setting for your application.
Page 25
Using QuickTime Playback
XCLAIM VRÕs QuickTime playback acceleration allows
you to stretch even the smallest movies to full screen size
without compromising frame rate or image quality.
XCLAIM VRÕs hardware scaler maintains the original
quality of your QuickTime movie when scaling to a larger
sizeÑeven full screen.
XCLAIM VRÕs QuickTime playback acceleration displays
in millions of colors, even if the current color depth
setting is 256 colors or grayscale. When scaling video,
XCLAIM VR uses special hardware techniques (alpha
blending and chroma interpolation) to enhance the video
quality instead of just repeating pixels.
NOTE
To use XCLAIM VRÕs playback acceleration, you must have
QuickTime version 2.5 or greater installed on your computer. A
compatible version of QuickTime is included on the
XCLAIM VR Extras CD-ROM.
Optimizing Video Playback
When you scale a movie, your system switches from
QuickTimeÕs software scaler to XCLAIM VRÕs hardware
scaler to produce better results. However, QuickTime will
not switch to hardware scaling in the following situations:
¥ playing video in double size
Try manually scaling the video slightly off exactly double
the size.
¥
pausing the video
¥
using single frame advance
¥
watching the video in reverse
¥
playing a video that has not been saved in Cinepak or
Indeo compressed format
QuickTime clips must be in Cinepak (the most common
QuickTime movie format) or Indeo format to be scaled by
XCLAIM VR. To determine if a video will be accelerated
using XCLAIM VRÕs hardware scaler, check the video
format.
Page 26
To check the format of a video
NOTE
1.
Open the movie using Apple Movie Player.
2.
Select Get Info.
3.
From the 1st pull down menu, select Video Track.
4.
From the 2nd pull down menu, select Format.
5.
Read the format type. Remember, only Cinepak and
Indeo formats use XCLAIM VRÕs QuickTime
acceleration and hardware scaler.
Some multimedia titles on CD-ROM incorporate QuickTime
clips that do not allow movies to be stretched during playback.
These QuickTime clips cannot be accelerated while viewing the
multimedia title.
Using QuickTime Video Capture
Using XCLAIM VRÕs QuickTime capture, you can capture
up to 320x240 at up to 30 frames per second! You can
capture still images or QuickTime movies from video
tape, camcorder, TV or laserdisc. To capture video, you
can use the Xclaim Video Player or any application that
supports QuickTime capture.
Using XCLAIM VR’s Video In Connectors
You can connect a VCR or camcorder to one of your
XCLAIM VRÕs video in connectors. Use this feature to
capture video on your computer from an outside video
source.
To input a video signal from a VCR to your computer
NOTE
This procedure describes how to connect a VCR to your
XCLAIM VR. You can use this procedure to connect other
video sources, such as a camcorder, to the video in of your
XCLAIM VR.
1.
Turn off your computer and VCR.
2.
Ensure that XCLAIM VR is installed correctly.
3.
Determine if your VCR has an S-Video or Composite
video output connection.
Page 27
4.
Looking at the back of your computer, locate your
XCLAIM VR card.
5.
Using an S-Video or Composite cable, attach one end
of the cable to the video in of your XCLAIM VR card
and the other to the video out of your VCR.
6.
Turn on your computer and your VCR.
Using XCLAIM VR’s Video Capture with Third Party
Applications
XCLAIM VRÕs video input can be used with any third
party application that supports QuickTime capture
through video digitizer components. To determine if the
application supports QuickTime capture, see the
applicationÕs documentation.
To capture video using third party applications
NOTE
Page 28
Not all applications work exactly as described in this procedure.
See your application documentation for specific instructions.
1.
Ensure that the video source (VCR or camcorder) is
properly connected to XCLAIM VR. (For more
information, see ÒUsing XCLAIM VRÕs Video In
ConnectorsÓ on page 27).
2.
Launch the application and select the video capture
feature.
3.
Select the Video Settings.
4.
Select Source from the main popup menu which
normally is set to Compression.
5.
Ensure that the Digitizer is set to ATI Video Digitizer.
6.
Ensure that the Input matches the type of video
source (Composite or S-Video) you have connected
to XCLAIM VR.
Optimizing Video Capture
The quality of your capture depends on the quality of the
video source and the type of system you are using to
capture. Follow these suggestions to ensure that you are
getting the best capture possible:
¥
turn off virtual memory
¥
disable your network and Þle sharing capabilities (i.e.
AppleTalk)
¥
add additional RAM (32MB recommended)
¥
capture at 16 bit color depth (this gives better capture
rates than 8 or 32 bit color depth)
¥
defragment your hard drive
¥
turn off the menu bar clock
¥
reduce the size of the capture window (You will be
able to scale it to full screen later with XCLAIM VRÕs
playback acceleration.)
You need a high-speed hard drive with lots of available
hard disk space. An ideal drive would be an AV drive
(6MB per second) or a Fast drive (4MB per second) using
a SCSI-2 controller. Your drive needs to write at least 5MB
per second to capture video at 320x240 at 30 frames per
second. Check the speciÞcations of your hard drive in
your system manual.
Page 29
Make sure that you have the available hard disk space
you need to capture your video. If you capture 15 seconds
of video at 30 frames per second with a window size of
320 x 240, you need about 60 MB of hard disk space. After
you have captured your video, you can use postcompression to decrease its size. A typical 60 MB video
capture will compress to about 10 MB using the Cinepak
post-compression format.
For more information about optimizing QuickTime
capture, see the QuickTime FAQ (Frequently Asked
Questions) located on the XCLAIM VR Extras CD-ROM.

6.
Attach one end of an S-Video or Composite cable to
the video out adapter and the other to the video in
connector of your VCR.
Although the video out adapter has two connectors for
S-Video and Composite cables, you only need to connect
one to your VCR, either Composite or S-Video. If your
VCR has both input connections, S-Video will produce best
results.
You can connect a TV and a VCR to your XCLAIM VR
card using both output connectors on the video out adapter.
One must support the Composite format and the other
must support the S-Video format.

Turn on your computer, VCR, and TV.
If you are connecting your XCLAIM VR card to a VCR,
make sure that your VCR is connected to a television that
you can use as your computerÕs display. For information
about connecting a television to your VCR, see the
documentation supplied with your VCR.
NOTE
Now that you have connected your XCLAIM VR card to a
VCR, you need to enable Mac2TV.
Enabling Mac2TV
WARNING
!
¥
When you initially turn on Mac2TV Video Out,
your monitor display is dimmed. Monitors which
do not support the 60 Hz vertical refresh rate for
NTSC, or 50 Hz vertical refresh rate for PAL
required by video equipment may be damaged
when Mac2TV is enabled. Dimming your monitor
is a safety feature, protecting your monitor from
any potential damage.
¥
When using Mac OS 7.5.5, always use the ATI
Displays control panel to display the video signal
on your TV.
Mac2TV allows you to output a video signal to either a TV
or VCR. There are three methods of turning on Mac2TV;
through the ATI Displays control panel, through the Mac
OS Monitors & Sound control panel, and through the Mac
OS Control Strip.
When using Mac2TV you can either send the video signal
to a television or video recorder in PAL or NTSC format,
or use Simulscan to send the signal to both your computer
monitor and the video recorder or television. When
looking at the resolution list PAL, NTSC, and Simulscan
are listed to the right of the resolutions and frequency.
NOTE
Simulscan is only available at 60 Hz (NTSC) vertical refresh
rates.

Mac OS 7.5.5 since this is the only way to ensure the
proper video mode is displayed on your TV.
Page 35
Changing Display Configurations
Starting your Mac with Mac2TV enabled
If you have Mac2TV display enabled when you shut
down, the next time you startup your TV is your display.
If you shut down with Mac2TV enabled, and remove the
connection to the TV, the next time you startup the ATI
software switches the video signal to your computer
monitor.
Using a TV as your only display
If you are using television display only, disconnect your
monitor from your XCLAIM VR card. XCLAIM VR
detects that you have a TV attached and automatically
starts with Mac2TV display enabled.
Optimizing Mac2TV
You can optimize your TV display using the video out
preferences. Viewing images on your TV can be improved
by changing the contrast, brightness, or size of your
display.
Page 36
To set the video out preferences, click the Mac2TV icon on
the ATI Displays Control Panel.
Saturation, hue, and brightness are the three qualities
which constitute what we normally refer to as ÒcolorÓ.
¥
Saturation is the amount of color present that
distinguishes pale or washed-out colors from vivid
ones.
¥
Hue, often used as a synonym for ÒcolorÓ, is the
quality that distinguishes among red, green, yellow,
and so on.
¥
Brightness is related to the amount of light emitted by
your display or reßected from an object. This quality
enables you to describe an object as ÒbrightÓ or
ÒdimÓ.
Hue is generally not adjusted. Depending on the TV,
however, it may be necessary or desirable to adjust the
hue to approximate the monitorÕs display.
Contrast is a ratio of how far the whitest whites are from
the blackest blacks. If the contrast is too high, the image
may look stark, like pure white squares on a jet-black
background. If the contrast is too low, the image may look
gray or washed out.
Page 37
Color Blender adjusts the overall color shifts inherent in
NTSC and PAL signals. On some televisions and video
output devices, this color shift is more apparent than on
others. The minimum adjustment is automatically
determined by the XCLAIM VR card depending video
mode and resolution, TV standard, and vertical size of the
video signal. If you adjust the slider to a minimum level
lower than the level determined by XCLAIM VR, the
slider automatically moves back to the minimum level
determined by the accelerator card.
Anti-Flicker reduces the amount of display ßicker. Display
ßicker is both a distraction and tiring to your eyes, and is
most pronounced when text is being displayed.
Dot Crawl is an undesirable characteristic of many
Composite televisions that is seen as thin, jagged edges
moving around objects on the screen. The ÒFrozenÓ
setting freezes, or eliminates, the dot crawl, and is
especially useful for viewing pictures or stills. S-video
equipment does not exhibit this effect.
Reducing Edge Distortion
When using a television for your display, you may see
some edge distortion on the left and right side of your
television screen. This effect depends on your television
and the application you are running.
To reduce edge distortion, you can:
¥
increase the horizontal size by clicking the right Size
arrow, or
¥
reduce the brightness by adjusting the brightness
slider.
Viewing Text on Television
Due to the different technology used in the
manufacturing of televisions and monitors, standard text
may look too small on your television. You can
compensate for this by using larger fonts.
Page 38
To change your font size
1.
Click the Apple menu.
2.
Select Control Panels.
3.
Select Views.

Troubleshooting Tips
Before Contacting Customer Support
If you have a general question, or encounter problems
with your card, please review this information completely
before contacting Customer Support.
You can create a problem report from the ATI Displays
control panel. Please refer to the ATI Guide for
instructions on generating this problem report, and for
general troubleshooting tips not covered in this section.
Before calling about a suspected problem, please
complete the problem report, and have the report Þle
either on-screen or printed out for reference during your
call. Important information about your system is
automatically included when you generate the report.
Solutions to Common Problems
Why can't I get a resolution higher than 640x480?
¥
The problem likely relates to Monitor Sensing. Any
monitor connected to an Apple-type monitor port
must supply Òsense code informationÓ so that the
graphics card can conÞgure itself for the attached
monitor. If the detected sense code does not represent
the capabilities of your monitor, then the card cannot
conÞgure itself properly. You need to attach a monitor
adapter that supplies the proper sense code for your
monitor. Monitor adapters can be obtained from the
monitor manufacturer, or from your local Apple
Authorized Dealer.
Page 41
I am using a monitor adapter to supply the sense code,
but I only get one resolution, even though I have a
multiscan monitor. Why?
¥
If the adapter is conÞgurable, you need to adjust it to
one of the multiscan options that best matches your
monitor. If the adapter is not conÞgurable, you need a
new adapter with the proper sense code for a
multiscan monitor.
I have a monitor with three BNC connectors. Why won't
it work with my XCLAIM VR card?
¥
Monitors that only have three BNC connectors
require a synchronization (ÒsyncÓ) signal to be sent
down the green line. This is called Sync-on-Green
(SOG). ATI accelerator cards do not output an SOG
signal. Adapters are available for your Macintosh to
convert the separate sync signal from the ATI card to
an SOG signal for the monitor. Check with your local
Apple Authorized Dealer for availability of SOG
adapters.
I have a monitor with Þve BNC connectors. Why won't it
work with my XCLAIM VR card?
Page 42
¥
For a cable with Þve BNC connectors, ensure that they
are all connected to the monitor. If only three of the
cables are connected (i.e., R, G, and B), the monitor is
expecting a Sync-on-Green (SOG) signal.
¥
Some monitors may have a switch to set the monitor
to either SOG or separate sync. If the switch is set to
SOG, the monitor will show a scrambled display.
Setting the switch to separate/composite sync may
resolve the problem.
¥
A number of BNC cables, even though they are
designed for Macintosh computers, do not supply the
sense code needed by the graphics card. Using an
adapter which sets the appropriate sense code should
solve the problem.
Can the XCLAIM VR work in all Power Macintosh
computers?
¥
No, the XCLAIM VR only works with PCI-based
Power Macintosh computers. The minimum system
requirements for the XCLAIM VR are listed in ÒWhat
You'll NeedÓ on page 2.
Where can I get a memory module upgrade for my
XCLAIM VR card?
¥
Memory upgrade modules are available either from
your dealer, or they can be purchased directly from
ATI. For information about contacting ATI, click the
ATI icon in the Displays control panel.

3D Mode Table
The 3D mode table measures the number of full screen 3D
windows that are possible to display at a given resolution.
For example, a value of 2.75 means that there is enough
memory left over in the current mode to run 2 full screen
3D windows and another at 3/4 the size of full screen. A
value of 0.40 means that largest 3D window will be just
less than 1/2 the size of full screen.
In the following table, 3D windows are considered to use
a back buffer and Z buffer and no texture compression.
You could increase the number of full screen 3D windows
possible by using texture compression.
NOTE
3D acceleration is not supported when your color depth is 256
colors. In this color depth, there are too few colors to display
complex 3D textures.

Memory Upgrade
If you currently have a 4MB XCLAIM VR card, you can
upgrade to 8MB by adding a 4MB SGRAM upgrade
module.
By adding additional memory you do not gain additional
2D resolutions or color depths since a 4MB XCLAIM VR
card provides 32-bit colors in all supported resolutions.
However, adding an additional 4MB of RAM allows you
to open additional 3D windows and store additional 3D
textures.
To obtain a memory module upgrade, please contact ATI
or your dealer. For information about contacting ATI, click
the ATI icon in the ATI Displays control panel.
