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 'Dell™ - Self Test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working

5. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.

Built-in Diagnostics
Your monitor has a built-in diagnostic tool that helps you determine if the screen abnormality you are experiencing is an inherent problem with your monitor, or with your
computer and video card.
NOTE:
You can run the built-in diagnostics only when the video cable is unplugged and the monitor is in self-test mode.
To run the built-in diagnostics:
1. Ensure that the screen is clean (no dust particles on the surface of the screen).
2. Unplug the video cable(s) from the back of the computer or monitor. The monitor then goes into the self-test mode.
3. On the front panel, press and hold the Menu (button 2) and + (button 4) keys on the front panel, simultaneously for 2 seconds. A gray screen appears.
