Dell,1: Auto detect (digital input) self test feature check keeps dancing across the screen, if I push one of the monitor buttons then 2: analog input self test feature check keeps dancing across the screen, if I push that monitor button again then 3:Digital input pops up. just wondering how to get rid of this so i can use the monitor again.

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.

1. This box also appears during normal system operation if the video cable becomes disconnected or damaged.

2. Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.

If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
