Self-Test Feature Check (STFC)
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 both Digital (white connector) and the Analog (blue
connector) cables from the back of 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 green. Also, depending upon the selected input, one of the dialogs shown below will continuously
scroll through the screen.
4. This box also appears during normal system operation if the video cable becomes 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 system, because your monitor is
functioning properly.
NOTE: Self test feature check is not available for S-Video, Composite and Component video modes.
