6 Setting the Display Resolution
Choosing The Best Resolution
All Liquid Crystal Displays (LCDs) have a fixed resolution that is the same as
the maximum resolution that may be displayed on the LCD. In the case of the
DV151J/B the LCD resolution is 1024 x 768 pixels. This is also known as the
“native” resolution of the monitor. Lower resolutions can be displayed at full
screen through an interpolation circuit. Because the lower resolution must be
expanded, the quality of the displayed image is not as good as that available
when the native resolution is displayed. For optimal performance from any LCD
monitor, you must use the monitor’s native resolution.
If you are using Windows 95, 98, 2000, Me, XP or NT 4.0, you can change the
resolution as follows:
Double-click the Display icon in the control panel.
From the Display Properties dialogue box, select the Settings tab.
There is a slider that alters the displayed resolution.
Set the resolution to 1024 x 768.
For Windows NT users only: select a refresh rate of 60Hz and click Test.
A test pattern will be displayed. Make sure that there are no error
messages shown by the monitor. If an error message is displayed, check
the resolution and refresh rate settings or choose a different refresh rate.
Click OK to close Display Properties.
If you are using an Apple Macintosh, change the resolution by doing the
MacOS 8.x/9.x
Click the Apple icon at the top, left corner of the screen, select Control
Panel and then select Monitors.
Select a resolution of 1024 x 768 pixels with between 60Hz and 75Hz
refresh rate.
If refresh rates of 60Hz or 75Hz are not available, click Recommended in
the Show drop-down box and change it to All. Select the resolution and
refresh rate as above.
A colour depth of either Thousands or Millions is recommended.
Click the Apple icon at the top, left corner of the screen, select System
Preferences and then select Displays.
Select a resolution of 1024 x 768 pixels with between 60Hz and 75Hz
refresh rate.
A colour depth of either Thousands or Millions is recommended.
Supported Graphics Modes and Refresh Rate Selection
There is no need to choose the highest possible refresh rate when using an
LCD monitor. It is not technically possible for an LCD monitor to flicker. Even at
a refresh rate of 60 Hz you will get an absolutely flicker-free image.
For best results, it is important that you set the graphics adaptor to use one of
the monitor’s preset display modes shown in Table 1 on the next page. Other
graphics signals may be displayed poorly or not at all. Note that the
DV151J/B’s preset modes correspond to VESA or Apple Macintosh standard
graphics signals for these resolutions. All recent models of graphics adaptors
should be able to support these modes. For the native resolution of 1024 x 768
pixels, for example, refresh rates of 60, 70 and 75 Hertz are supported.
With Windows 95, 98, ME, 2000 or XP you can change the refresh rate of the
graphics signal as follows:
1. Double click the Display icon in the control panel.
2. From the Display Properties dialogue box, select the Settings tab and
click the Advanced Properties button.
3. For Windows 95, 98, and ME select the Adapter tab, for 2000 and XP
select the Monitor tab. The refresh rate selection field is located in the
centre, at the bottom of the dialogue box.
4. Choose a refresh rate that corresponds with one of the factory modes from
the table below.
5. Click Apply, and then OK twice.
Please Note:
• Graphics modes that are not listed in the table may not be supported. For
an optimal picture it is recommended that you choose a graphics mode
with a resolution of 1024 x 768 pixels that is listed in Table 1 on the next
page. Resolutions of 640 x 480, 800 x 600 and 1024 x 768 pixels are
supported. The default setting may require some adjustment before use.
• The displayed image may show some distortion or noise that can be
caused by the signal from the VGA card if it does not correspond with the
usual standard. This is not however, a problem with the monitor. If it is still
visible after using the Automatic adjustment, you can usually improve the
displayed image by manually adjusting the phase, clock and horizontal
position settings using the OSD. See Chapter 7, Adjusting the Monitor,
for more details.
• When you shut Windows down you may see interference lines on your
screen. This caused by the manner in which Windows controls the
graphics card at this point and is normal with all LCD monitors.
• To extend the service life of the product, we recommend that you use your
computer's power management functions to turn the monitor off after
extended idle periods.

Picture Optimisation
The easiest way to obtain an optimal picture is by using the Auto Adjustment
function in the OSD menu. This only works reliably if the graphics adaptor is set
to use one of the monitor’s factory modes (see Table 1 in the previous chapter)
and if you are displaying a suitable stationary image (such as the Windows
The monitor will remember the settings obtained by the auto calibration
settings and use them whenever you turn the monitor on. Note that you may
need to readjust the monitor if it is connected to a different computer or if the
computer’s graphics adaptor is replaced.
If you are still not satisfied with the result, you can enhance the image by using
the monitor’s manual adjustment functions.
Manual Picture Adjustment
Adjustments to the displayed image and audio volume are made using the
On-Screen Display (OSD), and the buttons on the front of the monitor.
To manually adjust the image:
Display your operating system desktop
Open the OSD menu by pressing one of the Function keys on the monitor.
Press Fn► or ◄ to select the Clock function.
Press ► or ◄ to increase or decrease the sampling clock to get the
optimum picture. Look closely at the picture displayed, especially
surrounding text and icons, for any movement or change. Adjust the Clock
setting and see how this affects this “noise” or movement. Make sure that
in correcting noise in one part of the screen the setting does not create it in
another. You should, with careful adjustment, be able to obtain a picture
with no visible noise in any section of the screen.
5. If some noise or distortion is still visible select Phase using the Fn► or ◄
6. With the Clock set to the optimal value adjust the Phase to further optimise
the displayed image. You should now be able, with a combination of the
Phase and Clock settings, to obtain a perfectly stable image.
7. Finalise the manual adjustment using the H. Position and V. Position
If you are still not satisfied with the result, try repeating the above procedure
using a graphics signal that has a different refresh rate.
Please Note:
You must use one of the factory modes when manually adjusting the picture. If
you are having difficulties generating a supported mode, ask your computer
dealer or the distributor or manufacturer of your graphics card for assistance.
The procedures described in this chapter should be performed for every
resolution and type of graphics signal that you wish to use. For example, if a
particular application requires a resolution of 800 x 600 pixels, but all other
applications use the monitor’s native resolution, you will need to display the
test pattern and make adjustments twice.
The monitor will remember your settings and use them whenever you turn the
monitor on. Note that you may need to re-adjust the monitor if it is connected to
a different computer or if the computer’s graphics adaptor is replaced.
Frequently Asked Questions
The image is blurred, how can I get the best quality picture?
Read chapter 6, Setting the Display Resolution, and select a graphics
signal with the correct resolution and refresh rate. Then read chapter 7,
Adjusting the Monitor, and make adjustments to the displayed image
based on these instructions.
Have you used a VGA extension cable?
If so, remove the extension cable and check the displayed image. Has the
image quality improved? Optimise the image using the procedures in
chapter 7 with the extension cable removed. Reconnect the extension
cable once the image has been optimised. Depending on the
characteristics and type of the extension cable, some blurring or distortion
may occur due to conduction losses of the extension cable. You can
minimise these losses by using an extension cable with better conduction
quality or with a built-in booster.
Does the blurring only occur at resolutions lower than the native
(maximum) resolution?
Please read chapter 6, Setting the Display Resolution. Select a graphics
signal that uses the monitor’s the native resolution (1024 X 768 pixels).
Why does the image look yellow, blue or pink instead of showing the
correct colours?
The most common cause of this problem is a loose VGA signal cable or
connector. Check that the cable is securely connected to the computer.
Check the VGA signal cable for damage. If any pins are bent or broken off,
contact your dealer or an authorised Mitsubishi Electric service agent (see
Chapter 10 for details).
No image is displayed, what can I do?
Check that the light (LED) next to the monitor’s power button is lit and is
green in colour. If the LED is green, press one of the Function Select
buttons on the monitor to access the On Screen Display. If the message
NON PRESET MODE appears there, please read chapter 6, Setting the
Display Resolution and reset the graphics card to one of the monitor’s
supported graphics signals.
If the LED is orange the monitor is in power saving mode. Press a button
on the computer keyboard or move the mouse to wake the computer. If that
does not help, check that the VGA cable is securely plugged into the
computer. Also check the pins of the VGA cable’s connector. If any pins are
bent or broken off, then contact your dealer (see Chapter 10 for details).
If the LED is not lit at all, check that the monitor is plugged into the power
supply mains socket and that the power switch is turned on. Check that the
monitor’s power switch is also turned on.
The image is or distorted, flashes or flickers:
Check that the monitor’s signal cable is securely connected to the
Read the chapters 6 and 7 of this manual, then select the correct
resolution, refresh rate and make adjustments based on these instructions.
The image is displaced in one direction:
Use the H. Position (horizontal position) adjustment in the monitor’s OSD
to reposition the image.
Read the chapters 6 and 7 and then select the correct resolution, refresh
rate and make adjustments based on these instructions.
