So I've been using the VW266H for a few days now, and I love it. I don't notice much color grading across it, and the viewing angles aren't too horrible - I had a few people watching episodes of a TV show on it (not straight-on viewing) without any problems. Didn't have any dead or stuck pixels when it came either, which is always nice. I didn't do any calibration, but then again I'm not too discerning as far as what I'm looking at - I haven't noticed any pink or blue hues like I'd seen mentioned in some of the reviews, but maybe I just can't see it.
Also.. it's big
It was a nice upgrade from my 19" 1280x1024 that I had before. So much more desktop space, and the pixel pitch is almost identical which is nice, because it means I don't need to have my glasses on for looking at it (like I do with some smaller pixel pitch monitors).
