I'd like to game on three monitors eventually, but I want to have a setup of two cheapo 22"s and my 28" in the middle, as the side monitors I don't believe will do a lot apart from point out when there's a baddy there.
The DPI is slightly different aswell but I'll live with that, I just don't fancy buying 2 more 28"s, when another of these 22"s is about £75 second hand.
I'll be using two VGA and one DVI/HDMI if that makes any difference?
