* What would it take to drive a display like this?

I'm pretty sure you can buy cards that will do 3840x2400. The GeForce4 Ti4200 in my desktop will do 2048x1536 and can output that via dual link DVI. But 2160p requires more bandwidth that dual-link DVI has: 4 times the bandwidth of 1080p (which requires
more than single link DVI can provide with standard blanking). With
reduced blanking it's doable with 2 dual link connections each running
at 139MHz (out of 165MHz possible). That's for 60Hz (i.e. 2160p60).<br><br>So you'd need a card that knows how to split that resolution through two DVI connectors, or two cards (probably the easiest and cheapest way).
