I'm using the Dell Ultrasharp Monitor U4320Q. There is no other way to put it - when I first bought it, I had doubts about my decision because this thing is _big_. You'll need to move your eye (and/or your neck) a bit more for the content on the edges which you almost never have to do for something like, say, 24" monitor.

However, few months down the line, this is the best decision I made for coding. The real estate makes a real difference. The quality of the panel is great and you soon get used to "bigness" and the ability to have so many split windows makes a huge difference in productivity. It'll probably really shine with a tiling WM/virtual workspaces (I use a non-tiling single workspace setup so that's just speculation though).

You still have to move few inches away if you are playing content full screen (my desk is wide but not very deep). I play Youtube videos expanded but not full screen and that is already big enough for me. For movies in full screen, I push my chair a bit away from the desk and put my legs on a small stool and then the experience is great.
