Why do you have to get the really expensive Samsung monitor?
I have an Asus VH226H

For 200 bucks, it's a crazy monitor! 21.5 inch's is not normally full 1080p resolution. If you look at the reviews on there, they complain about monitor bleed. I see none! I got it quickly and found ONE dead pixel in the corner that you can only see if your staring right at it on a white background.
