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.
The DRM is so stupid - now in the era of streaming you can get literally anything webripped day1.
DRM is obsolete (and it never really wasn’t tbh).
DRM is not to stop pirates, but to show investors and licence holders you are trying to stop pirates.
