Troubleshooting Your Monitor
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 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 the computer.
3.
Turn on the monitor.
This box also appears during normal system operation if the video cable becomes disconnected or damaged.
4.
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; your monitor is functioning
properly.
