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 o both your computer and the monitor.
2. Unplug the video cable from the back of the computer. T
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 usage, if the video cable is disconnected or
damaged. The monitor will enter Power Save Mode after 5 minutes if left
at this state.
5. Turn o 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.
