Self-Test Feature Check
Your monitor provides a self-test feature that allows you to check whether 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. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital
(white connector) and the Analog (blue connector) cables from the back of computer.
3. Turn on the monitor.
4. This box also appears during normal system operation if the video cable becomes disconnected or damaged.
5. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer
system, because your monitor is functioning properly.
Common Problems

video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending
upon the selected input, one of the dialogs shown below will continuously scroll through the screen.
