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 Adden-
dum 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 loading the wallpaper, 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 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.
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.
