WARNING: Before you begin any of the procedures in this section, follow the
Safety Instruction
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. To ensure proper
Self-Test operation, remove VGA cables from the back of 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, one of the dialogs shown below will
continuously scroll through the screen.
4.
This box also appears during normal system operation, if the video cable
becomes disconnected or damaged. The monitor will enter
Power Save
Mode after 5 minutes
if left at this state.
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.
