I have seen good output on an AT&T color VGA and an IBM 12" monochrome.  If you
looked really close, you could see a bit of jittering on both.  The 12 picture
was crisper, but of course the dots are closer together.  If I could find a 12"
color VGA I'd be a happy camper.

I did not see anything on a Gateway VGA.  I think that it does not use TTL
level signals.  The LC will only drive TTL level signals, not low impedence,
according to Macintosh Tech Note #144.
