Plugable UD-3900C4 Not Allowing Video Streams (but Audio Works) on MBP M1Pro

USB Docking Stations UD-3900

When plugged into Plugable UD-3900C4, I am unable to stream video either through the TV App or through Safari Browser looking at sites like Netflix, Prime, etc. It’s weird because it was working but now its a no-go.

Hi,

Thanks for reaching out to Plugable support! I’d be happy to help with that.

This is likely due to video streaming content to that requires HDCP support by the displays they are being viewed upon. We do try to set the expectation that the two DisplayLink connections HDMI ports do not provide support for HDCP.

Here is a more detailed article on understanding HDCP:

I hope this information is helpful.
