Troubleshooting Procedures
This LCD Monitor was pre-adjusted in the factory with standard VGA
timing. Due to output timing differences among various VGA cards, you
may initially experience an unstable or unclear display when a new
display mode or new VGA card is selected.
This LCD Monitor Supports Multiple VGA Modes. Refer to Addendum for
a listing of the factory-preset modes supported by this LCD Monitor.
PROBLEM: Display is Unclear and Unstable
To stabilize and clarify your display, follow this procedure in this order:
1. It’s best to adjust the display on a screen displaying of vertical lines.
In Windows, load a wallpaper bitmap that has vertical lines in it. (or
you can select the window shut down screen)
2. After you have the wallpaper loaded, open the OSD and select the
“Clock” function. Press the top (or bottom) Adjustment Control button
and continue pressing the button until you see vertical dark and light
lines across the screen.
3. When you can see distinct light and dark vertical bands, stop pressing
the Adjustment Control button. Now press the opposite (top or
bottom) Adjustment Control button. The vertical dark and light bands
will decrease in number. Keep pressing the button until the distinct
bands disappear and you have a clear display.
4. Next, press the Function Control button to choose the “Phase”
function. The Phase will adjust the horizontal display. Press the top
(or bottom) Adjustment Control button and you will see horizontal dark
and light lines appear. The number of lines increases as you press
the button. Now press the bottom (or top) Adjustment Control button
until the lines disappear and you have a clear display.
