Troubleshooting
This LCD Monitor was pre-adjusted in the factory with standard VGA tim-
ing. 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 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:
1.
It is 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).
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 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 bottom (or top)
Adjustment Control button until the lines disappear and you have
a clear display.
