The display should be rock steady on LCDs. If you have a warranty on this local build or the monitor, it needs to be dealt with that way. If this was a CRT, I'd have you look at display settings or for electromagnetic devices near the monitor. CRTs sometimes need to warm up to stabilize as well but not LCDs. Have the "tech genius" at Best Buy (if that's where you got this or the monitor) take a look, try another display, video card, etc.
System: local build P4 3.0 GHz with 1 GB memory;
ATI 9200 Graphics card; new LCD monitor;
drive: Seagate 120 GB 7200 rpm
The display does a slight squiggly thing as if it were under water. A clue: it might be associated with a faint whining noise because it starts doing that when the noise starts.
The tech genius at Best B. suggested it was the settings on the font -- which seems unlikely to me.
It is possible is a line power issue which makes me think of an expensive voltage regulator.
Any ideas? Thanks.
