monitors

The monitor self test can only be run by shutting off the monitor and turning it back on. Some monitors require the power to be removed ie unplug the montior to force self test. (power shud be off for 5 min at least). Some monitors especially LCD FLAT Screens run a selftest when they are turned on or changed from analog to digital modes or Cable to PC mode.

Primarily more emphasis shud be on Video card tests than the monitor itself!. And on video card test there numerous ones both by manufacturer and through third party software.
