Expanded AMD HDMI 2.1 Support Is Coming To Linux (gamingonlinux.com)

(Monday May 04, 2026 @05:00PM (BeauHD) from the wait-is-over dept.)


AMD is [1]preparing expanded HDMI 2.1 support for Linux , following earlier delays after the HDMI Forum [2]rejected an open source implementation of HDMI 2.1 as proprietary technology. As GamingOnLinux reports, AMD developer Harry Wentland submitted a [3]patch series to the Linux kernel mailing list, noting that it brings "HDMI FRL support to the amdgpu display driver" and that "DSC is still being tested and will be sent out later."

A [4]forum post on Phoronix from an AMD driver developer also said "a full implementation will ultimately be available once the patches are ready and have completed compliance testing."

Maybe now, I can do away with all these HDMI 2.1 to whatever Chinese adapters.

Anyone else getting a chuckle out of the HDMI Consortium, the current ruling kings of proprietary technology and implementations now that the MPEG LA tripped over their own genitals and made themselves redundant, rejecting open source implementations as "proprietary technology"?

Fuck HDMI. I still don't know why people are using that shitty port when DisplayPort is royalty-free, has better specs, is supported by everyone, and can be used over other cables that don't have all the licensing attachment (USB-C

Well in my case, my Graphics adapter does not offer Display Port and I'm not about to buy a new one at current prices. My monitor supports both and this will be good news for me - once it comes.

HDMI is the new VGA. It allows the use of TVs, older monitors, etc. I have an ancient 1080p monitor plugged into a PC as a secondary display. The overhead projector used for presentations is often HDMI.

Because it is ubiquitous.

But because the pesky licenses, for example, the Commander X16 retro computer uses a good old VGA port. :)

The last time it happened, Liam was amused to be called "a fansite" :D

The magician is seated in his high chair and looks upon the world with favor.
He is at the height of his powers. If he closes his eyes, he causes the world
to disappear. If he opens his eyes, he causes the world to come back. If
there is harmony within him, the world is harmonious. If rage shatters his
inner harmony, the unity of the world is shattered. If desire arises within
him, he utters the magic syllables that causes the desired object to appear.
His wishes, his thoughts, his gestures, his noises command the universe.
