I run five pcs, so I need five monitors.

I'm with the people above that the best HDTVs are only 1920x1080 (and most AREN'T! Commonly the cheaper HDTVs are only 1380x760 or something close to that, and the cheapest are even worse.).

Having said that, I use 2x28", 1x19", 1x20", 1x22". If I were to go out and buy new monitors, I think I'd either stick with one 28" in the center, and have two 22" to the left and right (stacked on top of each other). Or perhaps all four be 24". As it is I could do with less whiplash, being as my monitors are in a 6 foot wide U shape in front of me, and my main monitor is on the far left.
