Your LCD Display provides a self test feature that allows you to check whether your LCD Display is 

functioning properly.

Turn off both your computer and the LCD Display. 

2)

Unplug the video cable from the back of the computer. 

3)

Turn on the LCD Display. 

 

The figure shown below ("Check Signal Cable") appears on a black background when the LCD 

Display is working normally even though no video signal is detected: While in the Self-Test mode, 

the LED power indicator remains green and the figure moves around on the screen.

 

4)

Turn off your LCD Display and reconnect the video cable; then turn on both your computer and the 

LCD Display 

If your LCD Display screen remains blank after using the previous procedure, check your video controller 

and computer system; your LCD Display is functioning properly. 

 

 

 

You can even view the screen at a resolution of 1360X768. However, you will receive the following 

message for a minute; You can choose to change the screen resolution or stay in the current mode during 

that time. And if the resolution is more than 85Hz, you will see the black screen because the LCD Display 

does not support over 85Hz.
