The floating 'Dell Self-test Feature Check' dialog box should appear on-screen on a black background if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
- This box also appears during normal system operation if the video cable becomes disconnected or damaged.
- Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.
