Valve: HDMI Forum Continues to Block HDMI 2.1 for Linux (www.heise.de)

The HDMI Forum, responsible for the HDMI specification, continues to stonewall open source. Valve's Steam Machine theoretically supports HDMI 2.1, but the mini-PC is software-limited to HDMI 2.0. As a result, more than 60 frames per second at 4K resolution are only possible with limitations.

AMD is part of the forum but can't get them to accept their own open source driver. I guess we can't complain or shame all of them in one. I wonder who voted reject vs accept.

Sad.

Then AMD needs to apply more leverage or start an awareness campaign with as much shit PR for every business supporting them.

Fewer than 80 members. 15k/year membership fee and very lax joining requirements. $1.2M gets you majority allowing you do to whatever even with 100% of current members opposing :P

How hilarious would it be if the AMD board member was the one who veto'd the driver 😅

[–] tty5@lemmy.world 9 points 1 day ago

AMD has had the code ready to include in their open source driver for a while and has been trying to get HDMI Forum to let them release it for a long time https://www.phoronix.com/news/HDMI-2.1-OSS-Rejected

Wild to see DisplayLink among the companies here.

~~Know~~ be your enemy, they say.

But jokes aside, I believe DisplayLink's focus is primarily on the client<->docking station part, with docking station<->monitor usually still being HDMI/DP (same with direct client<->monitor links). So they still have to interface with it some way or another.
