Hi all, I'm not actually doing this, but am curious: What would be the best way do use 4 monitors on a Mac (lets say a Macbook.) I'm guessing: 1 MiniDP -> DVI, and 3 USB-> DVI? Could you just run the USB -> DVI off of a hub? I know the adapter itself handles refreshes if nothing is occurring on the screen. But, with three USB adapters, would that hamper the normal performance of the computer quite a bit?
