I'm in the market for a 13" MBP and a 27" NEC PA-271 wide gamut monitor. The only way to connect a large (27" or larger) monitor to a 13" MBA (2011) is through a mini display port to dual link DVI adapter. Now, when you read reviews on Amazon and Apple.com, you find that for many people this doesn't work. http://store.apple.com/us/product/MB571Z/A Why? What do you do to make it work. I want to know before I buy the large display. What do I have to do to make it work? Or is there a real problem with the adapter?
