WARNING: Before you begin any of the procedures in this section, follow the Safety instructions.
Self-test
Your 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 your computer and the monitor.
2. Unplug the video cable from your computer to ensure proper self-test operation.
3. Turn on the monitor.
A dialog box should appear on the screen, indicating that the monitor is working correctly and it is not receiving a video signal. While
in self-test mode, the power LED remains blue (default color).

NOTE: The message may vary slightly depending on the connected input signal.
NOTE: This dialog box also appears during normal operation, if the video cable is disconnected or damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
After performing the above steps, if the monitor displays no video output, then the problem may be with the graphics card or the
computer.
