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 dis-

play 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 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 in-

creases as you press the button. Now press the bottom (or top)
