Troubleshooting
WARNING: Before you begin any of the procedures in this section, follow the
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 the back of the computer. To ensure proper self-test operation, remove all digital and the analog
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 monitor cannot sense a video signal and is
working correctly. While in self-test mode, the power LED remains white. Also, depending upon the selected input, one of the
dialogs that are shown below will continuously scroll through the screen.
4. This box also appears during normal system operation if the video cable is disconnected or damaged.
5. 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, because your
monitor is functioning properly.
Built-in diagnostics
Your 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 graphics card.
To run the built-in diagnostics:
1. Ensure that the screen is clean (no dust particles on the surface of the screen).
2. Using the joystick, navigate on the OSD menu and select Others > Self-Diagnostic.
3. Press the joystick button to start the diagnostics. A gray screen is displayed.
4. Observe if the screen has any defects or abnormalities.
5. Toggle the joystick once again until a red screen is displayed.
6. Observe if the screen has any defects or abnormalities.
7. Repeat steps 5 and 6 until the screen displays green, blue, black, and white colors. Note any abnormalities or defects.
If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the monitor is functioning properly. Check the
graphics card and computer.
The test is completed when a text screen is displayed. To exit, toggle the joystick control again.
