Bryan,

Be sure no fluorescent or halogen lights are nearby either.  They use
transformers which will mess up a monitor.   I had two monitors replaced at
work because of a fluorescent lamp that was on (without a bulb in it yet!!)
and it made the monitor jittery.   Unplugged the lamp and the problem
disappeared!
