That area has been a long standing complaint. That is, what you see on one machine doesn't match on another. Since this has been an annoyance since about Windows 3.0, I don't thing Microsoft is going to cure this.
Running: XP Home
Desktop: HP A1012X
Monitor: Compaq V720
Somethings displayed on this monitor do not line up properly. One program that we run is Active Security Monitor. It looks find on my computer, but on my Husband computer it does not display properly and some online games fill the screen on my monitor but on his they are small. I have try changing the screen resolution but this does not do a thing to fix the problem. I though I would try the forums again to see if someone has any idea what the problem is, before I take it in to be look at. Thanks in Advance!
