Troubleshooting  
This LCD Monitor has pre-adjusted using factory standard VGA timings. Due to the output timing  
differences among various VGA cards in the market, users may initially experience an unstable or  
unclear display whenever a new display mode or new VGA card is selected.  
Attention  
This LCD Monitor Supports Multiple VGA Modes.  
Refer to the Standard Timing Table for a listing of modes supported by this LCD Monitor.  
PROBLEM Picture is unclear and unstable  
The picture is unclear and unstable, please perform the following steps :  
1. Enter PC to “Shut Down Windows” status while you’re in MS-Windows environment, except  
Windows XP. In Windows XP open the specific application where the problems appear.  
2. Check the screen to see if there’s any black vertical stripes appear. If there are, take advantage of the  
“Clock” function in OSD menu and adjust (by increment or decrement numbers) until those bars  
disappear.  
3. Move to “Phase” function in OSD menu again and adjust the monitor screen to its most clear  
display.  
4. Click “No” on “Shut Down Windows” and back to the normal PC operating environment.  
PROBLEM There is no picture on LCD Monitor  
If there’s no picture on the LCD Monitor, please perform the following steps:  
1. Make sure the power indicator on the LCD Monitor is ON, all connections are secured, and the  
system is running on the correct timing. Refer to Chapter 3 for information on timing.  
2. Turn off the LCD Monitor and then turn it back on again. If there is still no picture, press the  
Adjustment Control button several times.  
3. If step 2 doesn’t work, connect your PC system to another external CRT. If your PC system  
Functions properly with a CRT Monitor but it does not function with the LCD Monitor, the output  
timing of the VGA card may be out of the LCD’s synchronous range. Please change to an  
alternative mode listed in the Standard Timing Table or replace the VGA card, and then repeat steps  
1 and 2.  
PROBLEM There is no picture on LCD Monitor  
If you have chosen an output timing that is outside of the LCD Monitor’s synchronous range  
(Horizontal: 24 ~ 80 KHz and Vertical: 49 ~ 75 Hz), the OSD will display a “Out of Range” message.  
Choose a mode that is supported by your LCD Monitor.  
Also, if the signal cable is not connected to LCD monitor at all or properly, the monitor screen will  
display a message “No Input Signal”.
