Self-Test

Your display provides a self-test feature that allows you to check whether your display
is functioning properly. If your display and computer are properly connected but the
display screen remains dark, run the display self-test by performing the following steps:
1. Turn off both your computer and the display.
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 display.
The floating dialog box should appear on-screen (against a black background), if the
display 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.
