7 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 monitor. In
the case of the DV154 the LCD resolution is 1024 x 768 pixels. This is also
known as the native resolution of the LCD monitor. Lower resolutions can
be displayed at full screen through an interpolation circuit. However the
lower resolution must be expanded and 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, you can change the resolution as follows:
1. Double-click the Display icon in the control panel.
2. Select the Settings tab from the Display Properties dialogue box.
There is a slider on the right-hand side in the middle of the dialogue
box that alters the displayed resolution. Set the resolution to 1024x768.
For Windows NT users only: select a refresh rate of either 60 Hz or 75 Hz
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.
3. Click OK to close Display Properties.
If you are using an Apple Macintosh, you may change the resolution by:
1. Click the Apple icon at the top, left corner of the screen, select Control
Panel and then select Monitors & Sound.
2. Select a resolution of 1024 x 768 pixels with either 60 Hz or 75 Hz
refresh rate.
3. If refresh rates of 60 Hz or 75 Hz are not available, click
Recommended in the Show drop-down box and change it to All.
Select the resolution and refresh rate as above.
4. A colour depth of either Thousands or Millions is recommended.

10
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
DV154’s preset modes correspond to VESA or Apple Macintosh standard
graphics signals for these resolutions. All recent models of graphics
adaptor 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. Select the Adapter 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

11
it is still visible after using the Automatic adjustment, you can usually
improve the displayed image by manually adjusting the phase,
horizontal position and pixel frequency settings using the "Geometry"
menu. See Chapter 8, 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.

8 Adjusting the Monitor
Picture Optimisation
The easiest way to obtain an optimal picture is by using the Auto button.
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 an appropriate full-screen test pattern.
Windows users should run the adjustment software (Auto.exe) from the
Utilities floppy disk to display the correct test pattern. Press the Auto button
with the test pattern displayed. You can quit Auto.exe by clicking the left
mouse button once and clicking on Exit.
Test patterns for other operating systems, in TIFF and JPEG file formats,
are also available from the File Downloads section of Mitsubishi Electric
Australia’s web site at www.mitsubishi-electric.com.au. Follow the link to
the TFT LCD monitors page and download a pattern with the resolution that
you need. Display the test pattern at its actual size (100% zoom), preferably
at full screen and then press the monitor’s Auto button.
The monitor will remember your 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.
The user’s controls include Power, AUTO, decrease (3), increase (4), Exit
and Enter.

13
Auto Automatically adjusts the vertical position, pixel phase, horizontal
position and pixel clock.
Exit Return to the main menu or exit the OSD menu without saving.
Press the exit key when the OSD is not displayed to adjust the
audio volume.
Enter Enter sub-menus, select items, save changes.
3Reduce the value of a setting. Move the selection cursor to the left.
Press to adjust Contrast if the OSD is off.
4Increase the value of a setting. Move the selection cursor to the
right. Press to adjust Brightness if the OSD is off.
To manually adjust the image:
1. Display the adjustment test pattern. This is the best way to observe
changes as you adjust the image. Windows users should run the
Auto.exe test pattern program provided on the Utilities floppy diskette.
For non-Windows operating systems, you also can use the test pattern
described in the previous section or another full-screen image, for
example the desktop of the operating system.
2. Open the OSD menu by pressing the Enter button on the monitor.
3. Press 3or 4to select the Geometry submenu and then press Enter.
4. Press 3or 4to select Clock and then press Enter.
5. Check the current setting. Increase or decrease the sampling clock to
get the optimum picture. Look at the centre section of the test pattern
that has alternating black and white vertical lines that are each 1 pixel
wide. There should be no vertical noise bands visible within the image.
The centre section will clearly show the alternating black and white
Auto Exit Ente r
A
uto Exit Enter Power

14
lines or a uniform level of noise will appear across the image once the
clock adjustment is correct. Close the clock submenu by pressing Exit.
6. Select Horizontal Position and press Enter.
7. Adjust the horizontal position so that the image is centred. Its width
should be the same as the visible width of the screen. Press Exit.
8. If some noise or distortion is still visible in the centre section of the test
pattern, select Phase and press Enter.
9. Adjust the Phase of the monitor’s sampling clock to optimise the
displayed image. The alternating black and white lines should be
clearly visible. Press Exit.
10. Press Exit twice to close the OSD menu and save your changes.
If you are still not satisfied with the result, try repeating the procedure using
a graphics signal that has a different refresh rate.
Please Note:
You must use one of the factory modes. If the Auto button is not working,
or the NON PRESET MODE message is shown on the OSD you are not
using one of the supported modes. 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.
Restoring the Factory Default Settings
Return to the factory settings for any display mode by pressing Enter to
open the OSD, selecting Information and then press the Enter button to
restore the default settings. The Recall function only affects the graphics
mode that is currently displayed.

15
On Screen Display Functions
The On Screen Display (OSD) provides functions that allow you to adjust
the displayed image, change the audio volume, reset the monitor and get
information about the displayed graphics signal.

9 Frequently Asked Questions
The image is blurred, how can I get the best quality picture?
♦Read chapter 7, Setting the Display Resolution, and select a graphics
signal with the correct resolution and refresh rate. Then read chapter 8,
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 8 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 7, 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 11 for details).
