Troubleshooting

This LCD Monitor was pre-adjusted in the factory with standard VGA timing.
Due to output timing differences among various VGA cards, you may ini-
tially 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 Appendix B
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:
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 select the Windows shut-down screen)
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.
When you can see distinct light and dark vertical bands, stop
pressing the Adjustment Control button. Now press the oppo-
site (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.
Next, press the Function Control button to choose the "Phase"
function. The Phase function 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 bot-
tom (or top) Adjustment Control button until the lines
disappear and you have a clear display.
