Hi... I'm getting my new MBP 2.4GHz Penryn (15" LCD) this Monday. I've been reading the tech sheet on Apple's website. Said that this MBP is fully supporting Apple Cinema Display 30" LCD. The thing is, they say ACD 30" needs a dual-link DVI. what does that means? What do i need to get so that i can connect this MBP using the ACD 30"? Do i need to buy 2 DVI-output cable? Or just get 1, plug it between MBP-ACD, and done? (because i do realize, MBP only has 1 video out port). Thanks!
