The 27" Ultrasharp is one display I was looking at but the price was more than I wanted to spend. I'm happy to report that two of my 27" displays have no dead/stuck pixels (one has a pixel that looks like it may be dead/stuck). I'm going to double check the other displays. Seeing that I do not have a main PC to connect them to, I tested each one on my 2013 13" Macbook Air.
Nice! I'd definitely wait until the 4k displays become more of the norm, then those prices will drop a good chunk. But that's just wishful thinking
