    Extremely laggoing behavior with 4K external display on XPS 15" 9560


      I just got a new XPS 15" with the following specs and I'm confused with the extremely lagging performance on external 4k screen (Samsung U28E590). The screen resolution is good, but he mouse is lagging, and when I work on Adobe Premier on the external screen, everything lags on it, the mouse the keyboard and the video. Any idea what's wrong?


      Weird enough, I had Macbook Pro 13" Late 2013 for 3 years before this PC and the performance was much better!


      The max refresh rate I can see is 30 Hz!
