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:

Turn off both your computer and the monitor.

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.

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.
