I'm about to assemble a PC and, at the same time, I want to upgrade my display. I intend to do gaming and watch movies with friends from farther away of course. So, I'm trying to figure out which. Some say that if you want 27" or bigger, you should buy one with high resolution (such as 2560x1600) but they cost a fortune. My 21" is too small for my purposes so I still would like a tad bigger one.
