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. 
The floating dialog box should appear on-screen (against a black background) if the flat panel display cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains blue. 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. 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.

Using the Built-In Diagnostics

The monitor has a built-in diagnostic tool that helps you determine if a problem you are having with the display is a problem with the monitor, your computer, or your video card. 

You can only run the built-in diagnostics when the video cable is unplugged and the monitor is in self-test mode.

 To run the built-in diagnostics:

Your monitor has a built-in diagnostic tool that helps to determine if the screen abnormality you are experiencing is an inherent problem with the monitor, or with the computer and video card. 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 and the + button. A gray screen is displayed.
  4. Check the display for any abnormalities.
  5. Press the + button on the front panel again. The color of the screen changes to red.
  6. Check the display for any abnormalities.
  7. Repeat steps 5 and 6 to check the display in green, blue, and white colored screens. 
  8. The test is complete when the white screen appears. To exit, press the  + Button again. If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the monitor is functioning properly. Check the video card and computer.
