Barry,

I've noticed a difference in display quality when driving my flat
panel with an nVidia gForce2 MX 200 vs. a Matrox G400. The flat
panel has both DVI and analog (15-pin) inputs, but so far I've only
had video cards with analog outputs. :( Anyhow, the Matrox looks
better -- more crisp with less shadowing.

Note, this was with my 15" 1024x768 monitor. I've looked at 17" 1280x1024
flat panels and my guess is that you'd have trouble getting *any* analog
card to give you crystal clear output.

That's a very good question. Add to it: a card that has DVI output(s).

Any recommendations?
