At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.

Does HDMI even work over USB C? Is there any reason for it to exist?

    A couple of years ago, I hooked up my laptop to a monitor and to watch a movie from a streaming service. Since the monitor (a budget AOC model) didn't support HDCP, it didn't play.

    Here's the amazingly sophisticated hack I used to get it working: Instead of using the monitor as an additional display, I mirrored the laptop screen to it. Millions of dollars developing DRM defeated by a single key stroke.
