I'm not seeing flicker in video content, but definitely see it in the GUI. The higher refresh rate of 720p also does wonders for sports programs. There are actually quite a few 1080p devices out now. The new Sony line, for example. Not sure how you get the signal there, but they have been advertising it far and wide. The display that I almost bought also supported 1080p.<BR>

The big downside for me is that they only support the 6600 and 6800 cards at 6629. I have a 6200.

The problem below is why using the DVI port is suboptimal... it isn't too back on SD content, but HD experiences quite a bit of tearing w/o VBlank support.<BR>
Here's a link to a thread that discusses the split screen bug:<BR>

Here are a few links to other people experiencing the VBlank problem. Basically, if I have VBlank enabled, and play back video content with Xv, the system hangs. On further inspection it isn't limited to DVI...<BR>
