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 your monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor and wait for five seconds.
If the monitor is functioning properly, you will see a box as shown in the following illustratiuon:
1. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
2. While in self-test mode, the LED remains green and the pattern remains on for 30 seconds.
If your monitor screen remains blank after you use the previous procedure, check your video
controller and computer system; your monitor is functioning properly.
