Self-Test Feature Check
Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If the monitor and computer connections are
correct and nothing appears on the screen, run the monitor self-test by performing the following steps:
1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer or output device to ensure proper Self-Test operation.
3. Turn on the monitor.
If your monitor screen remains blank after you reconnect the cables, check the video controller and computer.
