Monitor Self TestYour monitor provides a self test feature which allows you to check if your monitor is func-
tioning properly. If your monitor and computer are properly connected but the monitor
screen remains dark and the power indicator is blinking, use the following steps to perform
the monitor self test:
1. Turn off both your computer and the monitor.
2. Unplug the video cable from the computer or video card.
3. Turn on the monitor.
If the monitor is functioning properly, you will see a white box with a red border and
black text inside stating:
This box will also appear during normal operation of your system if the video cable
becomes disconnected or damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your
computer and monitor.
If your monitor screen remains blank after using the above procedure, check your video
controller and computer system; your monitor is functioning properly.
