Sounds like hdmi Forum are a bunch of twats. Time for a new format.

DisplayPort for life!

This is really frustrating. This is the only thing holding Linux gaming back for me, as someone who games with a AMD GPU and an OLED TV. On Windows 4k120 works fine, but on Linux I can only get 4k60. I've been trying to use an adapter, but it crashes a lot.

AMD seemed to be really trying to bring this feature to Linux, too. Really tragic that they were trying to support us, and some anti-open source goons shot them down.

Should… should we sic EU on them?

So why is it rejected?

Just because they're still trying to use HDMI to prevent piracy? Who in fuck's name is using HDMI capture for piracy? On a 24fps movie, that's 237MB of data to process every second just for the video. A 2 hour movie would be 1.6TB. Plus the audio would likely be over 2TB.

I've got a Jellyfin server packed with 4K Blu-ray rips that suggest there are easier ways to get at that data.

This sucks as all new TVs use HDMI2.1 for modern features and modern games consoles rely on those for 4k 60Hz HDR, etc.

So now Valve can't just make their own home console with Steam OS for TVs directly (and support high-end features at least).

What's the over/under that this was about preventing people getting around HDCP using a modified driver?

Alright, from now on I will never again buy any electronics with HDMI.

No disrespect meant towards GamingOnLinux, but this article from Tom's Hardware has a much better description of what's going on, including quotes.

This is the best summary I could come up with:

If you were hoping at some point to see HDMI 2.1+ on Linux with AMD + Mesa, you're out of luck right now as it's simply not going to be happening.

There's been a bug report on the Mesa GitLab of "4k@120hz unavailable via HDMI 2.1" that's been open for a few years now, with lots of comments and chatter about the issue.

In an update on the bug report, AMD engineer Alex Deucher commented: "The HDMI Forum has rejected our proposal unfortunately.

So if you're on Linux, it's going to continue to be best to buy hardware that uses DisplayPort.

On the NVIDIA side though, it seems like it may not be an issue, as developer Karol Herbst wrote on Mastodon: "Even though AMD might not be able to add support for HDMI 2.1, nouveau certainly will as Nvidia's open source driver also supports HDMI 2.1 so there is no reason to believe that at least some drivers can't support HDMI 2.1

It's quite backwards, but apparently having all the logic inside firmware (like Nvidia does) will probably help us implementing support for HDMI 2.1"

The original article contains 244 words, the summary contains 183 words. Saved 25%. I'm a bot and I'm open source!

Boo! Get off the stage HDMI Forum!

Eli5, what are the security risks of my HDMI cable?

Always thought that display port is better anyways lol. Anything that HDMI does or have that display port doesnt?
