Hey guys, I've got a question which I know the answers is probably no : I have the opportunity to buy the Dell P2715Q from a friend. I current have a macbook air mid 2012 which I know can only output 2560 by 1600 on an external display. My question is whether I can connect the 4k monitor on to my macbook air and run it on 2560 x 1440 instead of the 3840 × 2160 resolution of the monitor. If by any chance this is possible do I need any adapters or will the displayport cable -> thunderbolt port be sufficient? thank you!
