I noticed on my FE950+ when I look close up at the monitor text isn't completely still. In other words, there's some kind of 'glitchy' movement around letters. Is this normal for this monitor? I just purchased a 4.1 surround system and noticed when the bass of the subwoofer hit, the monitor's image would shake. I don't know if this has anything to do with the problem, if indeed there is a problem.
