some time ago I'd asked the same thing, but here's the thing: I've a 27" iMac and a 30" Dell monitor sitting next to it. after some advice, I orderded a Mini DisplayPort + USB to Dual-Link DVI Adapter from monoprice.com. with that cable it worked right away when it's booted into Windows... but somehow I don't manage to do it on the Mac... does anyone have any idea what's the catch? one more thing: what is the current state of playing Blu-ray movies on the Mac drive? is it possible?
