I bought this display based on a couple of positive things I read on here and bought it primarily to hook up to my nMP but I seem to be getting some lag of sorts. I'm using a Mini DisplayPort to Display Port to connect the monitor to the machine and I've got the DisplayPort Stream set to 1.2 but I still seem to be getting some noticeable lag. 1.2 is a definite improvement over 1.2, but something still feels off. Moving windows around feels slower and less responsive than it feels on my MacBook Air. I'm running the Yosemite DP2, incase that has anything to do with it. Really strange, though. Any help is appreciated. Thanks in advance!
