No problem for me also after updating my Desktop PC. Tested with TV, vids and OV, all OK but I'm using Madvr which does its own refresh rate changing, so the MP refresh changer is disabled.
Must unfortunately take my statement back. The problem is still there. It occurs whenever the screen refresh rate is changed. I don't use Madvr. With Disabled refresh rate changing no Problem with Black Screen.
Same Problem with Kodi.
I just installed two new clients with Fall Creators update in it and I am experiencing this symptom. Live TV and recorded tv works just fine. But any other video-content WHEN using dynamic refresh change brings black screen after video content is different refresh rate and mp does the change. When you press Ctrl-Alt-Del and escape from that screen you get your video back and can start watching...
Just a quick update, I have rolled back to 1703 following a number of very intermittent hangs, just 3 times this week, (nothing to do with MP which was not not running at the time), everything just frooze, no mouse,keyboard, and CAD did not function, had to hit the power button!
