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 
Appendix B for a listing of 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 vertical 
lines.  In Windows, load a wallpaper bitmap that has vertical 
lines in it (or you can select the Windows shutdown 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 
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 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
