Apple TV on MacMini M1 screen is black
Just updated to 11.3.1 and now my apple TV app just shows a black screen, but plays sound. This also occurs if I launch tv.apple.com via Safari, just sound and a black screen. This all worked fine before I upgraded to 13.3.1
This is a dual monitor system with 1080P and 4K monitors.
Any ideas as to problem?
