For Christmas I got a new Dell Flat Panel monitor - SE198WFP.
Periodically, it goes into this mode where evreything is displayed about 3 times the former size and a lot of colors are dropped out and it looks real crude. It still functions but after a bit it freezes. Sometimes when it freezes there are a series of black smudge like lines in a 3" x 1/2" box of smudge. I have no idea how to discribe this.
I reboot and everything is fine for a while and then it goes back to this strange look.
