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.

    The HDMI licensing BS makes it rather useless. At least most monitors and GPUs have DisplayPort now. It's mostly just TVs that are still limited to HDMI.

    I'm sure similar requirements stop DisplayPort and DVI from going open source.
