ewww, acer, sorry i have a personal HATE towards anything acer. Had some bad experience with alot of their products, laptops, monitors, desktops.... i dislike them very much. Looks like a nice monitor though, it's 21.5 though, not 22...it was a good deal, enjoy. Im thinking about picking up a 24" samsung soon.
Samsung have the nicest looking of all. They have some good designers in their lab back there. Only problem I've had is they sometimes crack when just transporting them places.
