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.
