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 DV156 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 or NT 4.0, you can change the
resolution as follows:
1. Double-click the Display icon in the control panel.
2. From the Display Properties dialogue box, select the Settings tab.
There is a slider on the right-hand side in the middle of the dialogue that
alters the displayed resolution. Set the resolution to 1024x768.
3. 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.
4. 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
DV156’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, 2000 or Millennium Edition 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 1024 x 768 pixels that is listed in Table 1 on
the next page. Resolutions of 640 x 480, 800 x 600, 832 x 624 and
1024 x 768 pixels are supported. Signals marked with an asterisk (*)
are not pre-adjusted in the factory. 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,
horizontal position and pixel frequency settings using the "Geometry"
menu. See Chapter 7, Adjusting the Monitor, for more details.
11
• 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.

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
once the test pattern is displayed. You can quit Auto.exe by clicking the left
mouse button once and clicking on Exit.
Test patterns 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.
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), three buttons and the adjustment wheel on the
front of the monitor.
The user’s controls include Power, AUTO, Exit and Enter. The rotary control
or wheel is used to select menu items and to change the values of image
parameters.

AUTO
Power:
AUTO:
Turn the monitor on or off.
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.
Wheel:
Turn this to select a menu item or make an adjustment
when using the OSD. Also acts as a hot key for Brightness
and Contrast adjustment.
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. For non-Windows operating systems, you
also can use the test pattern described in the previous section or
another full-screen image, such the desktop of the operating system.
2. Open the OSD menu by pressing the Enter button on the monitor.
3. Turn the wheel to select the Geometry submenu and then press Enter.
4. Five patterns will be shown at the top of the OSD window. Use the wheel
to select Clock and then press Enter.
5. Check the current setting. Use the wheel to tune 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.
14
The centre section will clearly show the alternating black and white lines
or a uniform level of noise will appear across the image. Close the clock
submenu by pressing Exit.
6. Use the wheel to select Horizontal Position and press Enter.
7. Adjust the horizontal position so that the image is centered. 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, turn the wheel to select Phase and press Enter.
9. Adjust the Phase of the monitor’s sampling clock by turning the wheel to
optimise the displayed image. The alternating black and white lines
should be clearly visible. Press Exit.
10. Press Exit twice and the OSD menu will ask you if you wish to save your
changes. Select Yes using the wheel and press Enter when the Yes
indicator turns blue.
If you are still not satisfied with the result, try repeating the procedure using a
graphics signal that has a different refresh rate.
Notes:
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 readjust 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. Is 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 11 for details).
♦ Check the monitor’s colour settings. Press the Enter button and use the
wheel to select the Color Settings menu. Select the Recall menu item
and press Enter.
17
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 the Exit button 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 11 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
computer.
♦ 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 Hor. Position (horizontal position) adjustment in the Geometry
menu of 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.
