Projector Output just white screen

[mrLuke]

Hi guys,

after upgrading my MacBook to BigSur I can't get my external display (projector screen) to work. When I right click on the output screen and choose Fullscreen projector and choose my HDMI adapter ( tried two) I get a complete white screen on my HDMI output.

I had it before couple times before the OS update but I could resolve it with restarting OBS. Now I can't. Can I fix that???

thanks for your help.

I have tested it further and have found that the issue only exists with my Hubs / dongles that use DisplayLink. It works fine with a normal USB-C to HDMI adapter.
