A few people and I have been trying to use the mini-displayport with the apple LED (note: not thunderbolt) 27" cinema display with no luck in getting it working. While we originally thought it may have been a driver issue, someone noted that the mini dp cable from the ACD doesn't seem to be connecting all the way in the surface pro. Has anyone been able to get this working? Is it a driver issue, or is there a mini-dp adapter (or extension) cable that someone can recommend that works? Thanks!
