DRM issues while using Displaylink
I am also interested in the resolution of this:
I was initially hogging both USB-C ports on my M1 MBP (one for charging and one for a single external display) until I discovered that my Dell D6000 dock supports DisplayLink. Right now, everything works fine EXCEPT for DRM issues. I can't watch Netflix on Safari whenever it detects I have an external display connected (regardless if the external display is directly connected via USC-C or through the dock via DisplayLink). The video actually plays fine because I can see subtitles including sound, but I only get a black screen.
This only happens in Safari. I can play Netflix videos just fine in Chrome, with or without an external display connected.
[...]
This would have been fine, but Chrome on MacOS doesn't support video qualities over 1080p unlike Safari. I also prefer using Safari over Chrome if I can help it. Issue also persists in other websites like Udemy, etc. Hopefully Apple fixes this DRM issue soon. It's been a huge pain in the ***.
