Alex Deucher:

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.

      Hdmi is a proprietary format controlled by companies that sell hdmi equipment. They have no benefit to having an open standard. They pay $15k a year each to keep it closed.

        DIsplayPort is also a proprietary format, just a bit less exclusive compared to HDMI. Ideally, we’d have an actual open standard. If DisplayPort wants to be that standard, they should be more open.

        It is closed in the sense that all the ISO specs are closed - you have to pay a decent sum of money to see the specs, and you’re not allowed to just copy them and show them to people that haven’t bought access.

        They are not closed like HDMI though - if you implement them, copy constants from the specs into the Linux kernel for example, that’s fine. Having actually open standards like Wayland would be a lot better though ofc…
