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.
Since we now have confirmation that an open implementation is legally impossible I would consider the HDMI forum to be a cartel and not a standarts comitee. Therefore it should be dismantled by anti-trust authorities asap.
anti-trust authorities
The same anti-trust authorities who have been ignoring completely?
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.
And game consoles. And basically anything that’s not a PC and a monitor.
It’s not just limited to PC’s. USB C has a DisplayPort alternate mode and many phones and tablets support it now. I’m rather surprised manufacturers haven’t started putting USB C ports on TV’s for video input yet.
Ah, i forgot some phones support straight displayport over usb. Still, wired display out on a phone isn’t exactly a common use case.
Why?
HDMI just needs to die. we have displayport anyway.
An other commenter here said that displayport is closed as well. Isn’t that true?
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…
The big reason for HDMI’s non-freeness is the use of on-protocol encryption. They learned from DeCSS, and the forum can’t let it happen again.
I’m sure similar requirements stop DisplayPort and DVI from going open source.
Would you mind elaborating? Honestly interested
There’s two I believe, HDCP which has been around since the DVI days and only now people bothered to implement, and another form of XOR-based on the actual cable itself done with a secret key, again, its DeCSS all over again but the HDMI Forum has never promoted the secret key.
Do they even make teevees with usbc or DP?
Disgusting… take note foss chads
FOSS when ever possible as much as possible.
