You should get a graphics card that has a DVI output however as using the analogue VGA signal will result in ghosting.

The culprit for this effect is the response time of the monitor, not (or at least very minimal) the way it's connected. Sure, DVI *is* better, but it helps especially to get sharper characters and pictures on the screen.
Typically to avoid the ghosting effect a 25ms (or lower, thats' even better but still rare) response time is needed.

This is going to be my next monitor (actually the 191T - the 19" version - but I can't find that model on the international site). It's specs are amazing : <25ms response time and a contrast of 500:1.The brightness of 250 cd/m² is very good. Also, I just LOVE the design.
