This article provides the information and guidance for troubleshooting issues with the Dell 1708FP and 1908FP Monitors


Using the Monitor Self-Test

The 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 the computer and the monitor.
  2. Unplug the video cable from the back of the monitor. To ensure proper Self-Test operation, remove all digital (white DVI connector) and analog (blue VGA connector) cables from the back of the computer.
  3. Turn on the monitor.
NOTE: A floating message box appears on screen with a black background, if the monitor is working correctly but cannot sense a video signal. While the monitor is in the self-test mode, the power LED remains green. Also, based on the selected input, a message box appears and floats on the screen. The dialog box also appears during normal system operation, if the video cable is disconnected or damaged.

  1. This box also appears during normal system operation, if the video cable becomes disconnected or damaged. The monitor will enter Power Save Mode after 5 minutes if left at this state.
  2. Turn off the flat panel display and reconnect the video cable; then turn on both the computer and the flat panel display.

If the flat panel display screen remains blank after using the previous procedure, check the video controller and computer, because the flat panel display is functioning properly.

NOTE: If the monitor screen remains blank, check the video controller and the computer.
