Self-Test

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.
3. Turn on the monitor.
The floating dialog box should appear on-screen (against a black background), if the
monitor cannot sense a video signal and is working correctly. While in self-test
mode, the power LED remains white. Also, depending upon the selected input, the
dialog shown below will continuously scroll through the screen.
NOTE: The message may be slightly different according to the
connected input signal.
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, because your monitor is functioning properly.
