HDMI Forum Rejects Open-Source HDMI 2.1 Driver Support Sought By AMD - Phoronix

Just a moment...

For three years there has been a bug report around 4K@120Hz being unavailable via HDMI 2.1 on the AMD Linux driver.
The wait continues...
This really bothers me. Closed standards locked behind a licensing fee may as well not be standards at all, in my opinion.
I don't understand why any hardware uses HDMI anymore anyway, what does it have that displayport doesn't?
HDMi foundation is founded by companies who own the home theatre environement (mainly movie conpanies and television) who puts DRM on HDMI to make it harder to illegally copy content like movies, ao they will always want to be anti open source because thats the request of streaming services/movie businesses. Its why for example, mobile devices have widevine levels. those levels basically determine how "unlocked" the device is and services will refuse to offer full functionality to unlocked devices because of it, be it audio or video.
Members of VESA, who control the displaypprt standard are generally computer companies are mostly not in the business of media, so they value specs over drm on changes, which for example a use case is that displayport allows for daisychaining diaplays.
Decades of being the standard in a/v. That's like asking, why don't we get rid of gas stations and just install electric chargers? Well, everybody's got gas powered cars.
Probably a lot more hardware using HDMI than DisplayPort? Just throwing a guess, tbh.
That being said, I might consider looking towards DisplayPort when I can get a new monitor...
CEC (technically I think displayport could support it, but generally isn't implemented) and ethernet up to 100Mbps.
Feature-wise probably next to nothing, and it's usually behind one or two generations in terms of bandwidth. HDMI is often the only port available on TVs though, so GPU makers likely can't afford to just leave it out.
eARC and 12gbp/s more bandwidth (4k@185hz vs 4k@120hz)
Otherwise the same
Can hook up to TVs…
My guess is it has something to do with DRM protection in the HDMI spec. I have no proof but it seems like it is always DRM that screws over open source.
