Self-test

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.
