pitrysha Posted January 24 Share Posted January 24 It could be a cable problem. They have different throughput. If I'm not mistaken, you need to use Displayport 1.4 Link to comment Share on other sites More sharing options...

pitrysha Posted January 24 Share Posted January 24 There is a cable to monitor Displayport 1.2, Displayport 1.4, Displayport 2.0 they are all different. What's in your kit? The higher the version, the better. Link to comment Share on other sites More sharing options...

pitrysha Posted January 24 Share Posted January 24 Displayport 1.4 is the minimum for Mac OS. Should work. Displayport 1.2 60 Hz will not work. Link to comment Share on other sites More sharing options...
