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 doesn’t 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.
