The $6m Dan said:Yeah, you will need a good PC to run 1920x1200, but the montior still looks good at 1650 x 1080 full screen.
It's a great monitor, you won't regret buying it. Make sure you get the newer model (2407) though as it supports HDCP so you can play HD DVD and BluRay discs at high definition.
Edit - I'm not actually sure if the 2407 has been released yet, I thought it would have been, but can't see it any where.
