Wait I see nothing on that moniter that would mean you need 2 DVIs per moniter. also.. thats a 27.5 Inch on 30" You cant have a screen larger then the dimensions, that's just silly. 27.6" x 20.7" x 10.6"
The fact that it is 2560x1600 tells me it is dual dvi according to the dvi spec. Also all 30" monitors are basically those dimensions. Bolth issues can be confirmed by the 3007WFP-HC which is the other screen I am considering b/c while a few hundred it has 50% less input lag.
