pitrysha Posted January 24, 2023 Share Posted January 24, 2023 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 https://www.insanelymac.com/forum/topic/355464-how-to-solve-black-screen-when-connecting-with-dp-cable/#findComment-2800471 Share on other sites More sharing options...

pitrysha Posted January 24, 2023 Share Posted January 24, 2023 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.

pitrysha Posted January 24, 2023 Share Posted January 24, 2023 Displayport 1.4 is the minimum for Mac OS. Should work. Displayport 1.2 60 Hz will not work.
