Flickering Monitors?

Anonymous Coward writes "Our SB Office runs a small 2 Server network with 4 workstations in the LAN, each connected to a dedicated APC Surge protector. The building has a backup power generator thus we didn't see the need for a UPS. For some odd reason all our monitors flicker a lot. We've tried everything from changing resolutions/refresh rates/video cards/monitors and spacing the monitors farther apart from each other - all to no avail. Could this be a building power supply problem? Some have suggested there may be some magnetic interference but visually inspecting the surroundings doesn't leave us with a culprit for the cause. Could this be fixed by the simple addition of a good UPS? Any help, tip or information would be gladly appreciated. Thank you."

A coworker of mine who is very sensitive to screen flicker had a similar problem--every monitor he tried would cause headaches. They gave him a flat screen and that solved the problem. That was at about the time when we figured out that on the other side of the wall from his cube was a wiring closet, so it was the electrical fields from the wiring closet messing up his monitor.

If you can find the source of the problem, you might be able to shield it.

Some evening after work, pack up your computer and monitor and bring it off site. See if it still flickers in a completely different environment. Either you have some electrical noise or you bought cheap monitors.
