Refer this article to run a Monitor Self-Test
Self-Test Feature Check
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.
If your monitor screen remains blank after using the previous procedure, check your video controller and computer system; your monitor is functioning properly.
Not Optimum Mode
If the vertical resolution is not optimum mode, you can still see the display but the warning message below appears and disappears after one minute.
The user must adjust the frequency within that one minute.
Refer to Specifications > Preset Timing Modes for the resolutions or frequencies that are supported by the monitor.
Symptoms and Recommended Actions
A monitor recreates visual signals received from the computer. Therefore, if there is trouble with the computer or the video card, this can cause the monitor to become blank, have poor coloring, noise, video mode not supported, etc. In this case, first check the SOURCE of the problem, and then contact a service center or your dealer.
(If it does, request an after-service for the main board of the computer.)
(Do not exceed 60 Hz when using the maximum resolution.)
Before calling for assistance, check the information in this section to see if you can remedy any problems yourself. If you do need assistance, please call the phone number on the Information section or contact your dealer.
