First, I want to say that I've been on the phone with Dells Tech Support line for almost an hour trying to get support for this display. Talked to 5 different people and not a single one can actually help me with this product. What in the world is the purpose of the "Express" Service Tag if you enter it and then have to talk to 5 people who can't even help you. Nothing about this is "Express".
Second, I have a P2715Q plugged into a 5k iMac and it does indeed run at 60Hz when I turn MST off, but it has these large moving lines and blanks out about once every 30 seconds. I was able to find this post and it appears that the previously suggested solution is to get a Rev A03. I have a Rev A03.
