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."

I also visit a cars webboard in the net and it's often asked something like this:

Q: I noticed some strange noice while car is moving - what could be the source?

A: ANYTHING!

You've got an office with 4 computers and lan. But instead of borrowing a UPS for a time or testing a monitor out of the office you just ask slashdot: could this be a power supply problem? Probably could and probably could not. Probably it's just visual interference with lamps, or a software problem (various versions of Windows tend to be very weird about monitor specs).

Even the producer of monitors is unknown. I doubt power supply will cause bad image on a new digital NEC and probably the best UPS would not help 15 years old samtron or like. You have much better chances to locate the problem where you are than we here.
