Hi,

as soon as I connect my Dell UD22 dock (two Dell monitors connected) to my MacBook Pro (M2, 2022), I cannot play any videos (YouTube excluded). Neither Wow, DAZN, Prime Video or videos in Apple Music show a moving picture. The screen stays black, sound is present. As soon as I disconnect the dock, the video appears.

I haven't found any settings that can cause this in any way.

I too am having this issue. YouTube streams videos just fine - but anything else, YT TV, Hulu, Peacock, NCAA March Madness, ESPN, Disney - literally everything else, sound but no video.

What gives?

It won't work because the display link basically is "observing" your screen. So the streaming services see it like you are trying to screen record the content. I haven't found a fix to it. It's extremely frustrating.

Reason: When you enable Screen Recording for DisplayLink, it becomes a DRM problem for Mac.

What doesn't work: I moved my Third Monitor to the HDMI port on my Mini...still didn't work, Screen Recording still in effect doing it's thing.

What works: Use Google Chrome>Enable Location for the Hulu's of the world>Disable Hardware Acceleration on Chrome.

I don't think there is a similar "Hardware Acceleration" equivalent in Safari.

Using Chrome with hardware acceleration disabled fixed this issue for me. :)
