WARNING: Before you begin any of the procedures in this section,
follow the
Safety Instructions
.
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 blue. 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.
