The HDMI Forum has rejected our proposal unfortunately. At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.

      You forget every desktop GPU having 3 DisplayPorts and only 1 HDMI, and USB C supporting DisplayPort?

      In my experience, its cause monitors are already over priced, and adding a display port to it seems to add at least another 100 on top of that.
