I have a now-old Dell 30" monitor, that runs 2560x1600. I have a (mini)DisplayPort to Dual-link DVI adapters, which plug into the Thunderbolt port - you know, the $100 one - and use it with my Air, and it works superbly. Bravo. Next step is to buy a 27" iMac, so I'm wondering if I'm going to be able to use the same adapter to drive that same 30" monitor. I'm thinking there should be enough graphics power to push all those pixels, though sure, I won't be playing dual-mon games or anything. Workable, or is there an issue?
