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. To ensure proper Self-Test
operation, remove all digital and the analog 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.
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.
