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 by the LCD panel. In the
case of the DV172 the LCD resolution is 1280 x 1024 pixels. This is also
known as the native resolution of the monitor. Lower resolutions can be
displayed at full screen through an interpolation circuit. However 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, 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
1280x1024.
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 1280 x 1024 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.

12
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
DV172’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
1280 x 1024 pixels, for example, refresh rates of 60, 70 and 75 Hertz are
supported.
With Windows 95, 98, 2000, XP or Me 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, 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 1280 x 1024 pixels that is listed in Table 1
on the next page. Resolutions of 640 x 480, 800 x 600, 1204 x 768
and 1280 x 1024 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

13
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 is 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 monitor’s controls include Power, AUTO, increase (4), decrease (3),
Exit and Enter.
Auto Exit En ter
A
uto Exit Enter Power

16
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 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 4or 3to select the Geometry submenu and then press Enter.
4. Press 4or 3to 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
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.
