So I want to connect 3 24" 1920*1080 monitors to my Mac Pro. I already have 1 connected through the Mini DisplayPort to DVI to HDMI. Now I still have two monitors left and 1 DVI-I Dual Link port open. What kind of splitter can I buy to connect this 1 port to my two monitors? And yes I know I should just add a GT 120, but I'd like to know what kind of splitter would work. Does best buy carry any of these? Thanks guys.
