Troubleshooting

WARNING: Before you begin any of the procedures in this section,

follow the Safety Instruction

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 the Analog (blue connector)

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 blue. 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.
