Symptoms & Recommended Actions
1. Self-Test Feature Check
Your monitor provides a self test feature that allows you to check whether your monitor is functioning 
properly.
1. Turn off both your computer and the monitor.  
2. Unplug the video cable from the back of the computer.  
3. Turn on the monitor.  
The figure shown below ("Check Signal Cable") appears on a black background when the monitor is 
in its normal working condition though it does not sense any video signal: While in the Self-Test 
mode, the LED power indicator remains green and the figure moves around on the screen. 
Failure of any of the boxes to appear indicates a problem with your monitor. This box also appears 
during normal operation if the video cable becomes disconnected or damaged. 
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the 
monitor.
If your monitor screen remains blank after using the previous procedure, check your video controller and 
computer system; your monitor is functioning properly.
2. Video mode not supported
This indicates the display resolution or refresh rate is not properly set on your computer video card. Reboot 
the computer in Safe Mode and select "Default" in the "Refresh Rate Unknown" box while setting Adapter 
for Display Properties. 
Sometimes the screen turns black without the "Video mode not supported" message appearing on the 
screen. This indicates the monitor is set for a frequency out of range or the PowerSaver mode is on. 
Contact the computer dealer or manufacturer for information on Safe Mode Booting.
Refer to Specifications >

by the monitor.
