I do have two receivers, one a Rio, and now this Dell. The Rio has a perfect display, so the .arf is not at issue. The reason I'm convinced the Dell's display itself is OK is that it does make a couple of perfect displays, then as you get into other parts of the menu it becomes unreadable. So I think, unless the driver chips are actually on-board to the LCD, that the display is OK and whatever is driving it is not...

I keep looking for a cheap receiver to buy, so I have a third unit to play with--I am reluctant to take my working Rio out-of-service and risk hosing it up, just to prove my theory about the Dell's display...
