Hey, I have a U3100 in my garage, I'll try to get some pics for you when I get it hooked up, but won't be real soon.
FWIW, vector games at 800x600 on VGA/SVGA arcade monitors look absolutley fine to me. Heck, at 640x480 I don't notice much of a difference. I guess if you paused the action, put your nose up to the screen and then had a fine dot pitch pc monitor right there to compare with, yes the pc would look better. Fact is, vector games look best...on a vector monitor.
