So I got the U2410 on Friday and used it thru the weekend. Overall it's a great monitor, but I'm a bit disappointed with the viewing angles in portrait mode. The two 2007FPs I have at work are much better. The black levels also don't seem as good. Pretty much everything else about the monitor is great.
Also, agree on the 2311. That is a fantastic price, if you don't mind 1080.
