I'm personally using one of these
HP LP2475w and I love it. I've been thinking about getting a couple more and setting up a multipanel display, but I'm not sure if I have room on my desk. I've even got my XBox plugged into it through the Composite inputs.
My previous monitor was the 2ms version of the
LG LW226WT. It was fine, bu the color and viewing angles weren't that great, especially when going from one corner of the screen to another. The HP has an IPS panel, and while it is theoretically slower in response rate, I've never noticed it, and with the far better colour and picture I see things that I never saw on the LG.
