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 Digital (black connector), the
Analog (blue connector) cables and DP (black connector) 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.
