Self-TestYour 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 remains dark, run the monitor self test by performing the following steps:Turn off both the monitor and the computer. Unplug the video cable from the computer. To ensure proper Self-Test operation, remove both the Digital (white connector) and the Analog (blue connector) cables from the computer. Turn on the monitor. With no connection to the computer, a dialog box should appear on a black screen advising you that there is no video connection. While in Self-Test mode, the power LED will remain white. This is an example of the dialog box that will appear (the model or type of connection specified may vary): This box 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. Turn off your monitor and reconnect the video cable, then turn on both the monitor and computer. If the monitor still remains dark after re-connecting to the computer, the problem is somewhere other than the monitor and may be with the computer itself or the video controller. If the Self-Test feature does not function, contact Dell Technical Support. Note: Self-test feature check is not available for S-Video, Composite, and Component video modes. Back to Top 2. Built-In DiagnosticsYour 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. These diagnostics can only be run when the video cable is unplugged and the monitor is in Self-Test mode.Note: You can run the built-in diagnostics only when the video cable is unplugged and the monitor is in self-test mode. Ensure that the screen is clean (no dust particles on the surface of the screen). Unplug the video cable(s) connecting the computer and monitor. This will place the monitor in Self-Test mode. Press and hold Button 1 and Button 4 on the front panel simultaneously for 2 seconds. A gray screen will appear. Carefully inspect the screen for abnormalities. Press Button 4 on the front panel again. The color of the screen will change to red. Inspect the display for abnormalities. Repeat steps 5 and 6 to inspect the display with green, blue, black, and white screens. Note: The test is complete when the white screen appears. To exit this mode, press Button 4 again.If you do not detect any screen abnormalities using the built-in diagnostic tool, the monitor is functioning properly. Check the video card and computer.
