Upgrade to Monterey makes streaming video picture black while sound is fine.
I just upgraded to Monterey, version 12.5. this morning. This evening I tried to watch several shows on Netflix and also on Amazon Prime, but while the sound played fine, the picture was black, no matter what show I chose to watch. The picture for video advertisements showed ok, but not the picture for the program itself.
Hulu, on the other hand, works fine.
Anyone have any suggestions?
