I've read before that my macbook pro 15" with regular display port wont support the 27" displays, can anyone confirm this is true? even with the Mini DisplayPort to Dual-Link DVI Adapter (http://store.apple.com/us/product/MB571Z/A?)
I'm using one of those with a 13" mid2010 mbp to power a 30" display at 2560x1600. It works, just make sure you use a dvi-d cable as well, most of the complaints I noticed about it not working when I was researching it seemed to be because the person hadn't actually got a dvi-d cable to go with the adaptor.
