WARNING: Before you begin any of the procedures in this section, follow

the

Safety

instructions.

Your monitor provides a self-test feature that allows you to check if your monitor is functioning

properly. If your monitor and computer are properly connected but the monitor screen remains

dark, run the monitor self-test by performing the following steps:

1. Turn off both your computer and the monitor.

2. Disconnect all video cables from the monitor. This way, the computer does not have to be

involved.

3. Turn on the monitor.

If the monitor is working correctly, it detects that there is no signal and one of the following

message appears. While in self-test mode, the power LED remains white.

cable is disconnected or damaged.

4. Turn off your monitor and reconnect the video cable; then turn on your computer and the

monitor.

If your monitor remains dark after you reconnect the cables, check your video controller and

computer.
