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.

It's got DP as well though so it's not all that bad. We really should be pushing manufacturers over to DP anyway.

It's literally the same feature set.

HDMI Forum has fewer than 80 members and membership fee is 15,000 USD/year. Valve could spin up 80 companies, have them join the forum for a low low price of 1.2M USD and outvote remaining members to open source the entire spec.

This is hilariously plausible. Someone SCUBA down to Gabe and give him the idea.

[–] Katana314@lemmy.world 20 points 3 days ago (1 children)

dives to 50 feet, removes tube from mouth to shout to Gabe, and fucking drowns

[–] utopiah@lemmy.world 17 points 3 days ago (5 children)

FWIW (and I know it's not the joke...) it's perfectly fine to remove the mouth piece while scuba diving. In fact it's part of basic training. You should be able to remove the mouth piece and take another one, your octopus or the one of your buddy, in case there is an incident.

No... the real question for a good diver is how the heck you're going to say HDMI 2.1 with hand signs! /s

You breathe through an octopus? Don’t they need that oxygen themselves?

Does it have to be companies? Could individual people just have 15k, and join? We just need 81 new members.

Console manufacturers all just need to switch to displayport to encourage tv manufacturers to do the same. No one's going to not buy a ps6 or steam machine because they have to use a little dp-hdmi adapter, but they might be a little more likely to choose a tv that doesn't need an adapter over one that does

[–] fluffykittycat@slrpnk.net 55 points 4 days ago (28 children)

What about shipping an adaptor? DP to HDMI for the transition?

Are people just forgetting it has a displayport also? Just ignore HDMI, they got greedy, onto the rubbish pile they go.

[–] pressanykeynow@lemmy.world 97 points 3 days ago (1 children)

The people who block HDMI for Linux are also the people who make TVs and other media stuff. So you may not be able to use displayport or hdmi just because some rich people decided so to make more profit.

[–] YiddishMcSquidish@lemmy.today 40 points 3 days ago (1 children)

This is what I said the other day about this issue. Good luck finding a decent tv with display port! Those fuckers are rare and expensive!

[–] Routhinator@startrek.website 24 points 3 days ago (15 children)

They are called monitors, and yeah expensive but then you don't get a "Smart TV" with tracking and bullshit.

Basically no modern TV has displayport except for few that come with USB-C

[–] LorIps@lemmy.world 27 points 3 days ago (4 children)

DisplayPort to HDMI adapters are quite cheap and don't add latency.

The problem is that many TVs have HDMI, but no DP.

The HDMI forum can go fuck itself

[–] count_dongulus@lemmy.world 63 points 3 days ago (1 children)

It's $1.2M to gain majority share on the HDMI board, but it sure would be nice if someone gave $1.2M to one of the engineers with access to that cryptographic DRM keys for the binary to "apparently get hacked" and have the keys magically appear online.

[–] falseWhite@lemmy.world 13 points 3 days ago* (last edited 3 days ago) (5 children)

Wouldn't make it legal to use them anyway and a big company like steam couldn't get away with it.

It would still be great for the open source community working on personal projects and such

[–] count_dongulus@lemmy.world 13 points 3 days ago (2 children)

I bet we would start to see chinese adapters showing up on the market with DisplayPort to HDMI2.1 though.

I wish I could buy hardware without HMDI at all so they got no money from me.

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.

[–] Bakkoda@lemmy.zip 41 points 4 days ago

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

[–] tty5@lemmy.world 27 points 4 days ago

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

I recently watched a video about HDMI. I didn't hate HDMI but now I kinda do.

Unfortunately most standards bodies are pretty much this stupid though. Blu-ray, DVD, USB, hell even codecs like H265 and MP3 have governing bodies that are mostly enterprises enforcing their collective power on standards. That’s good in ways because it means they all have to decide on a standard that’ll work wihh to pretty much anything, but bad because they can also enforce bullying like HDCP onto consumers.

We need more DisplayPort in the world - and better support for multi-monitor setups under Linux.

While infuriating, I think people who care about features limited to hdmi 2.1 are people having monitors with display port and people who use the box as console on “normal tv” are happy with 4k60

But I hate, that there is no wide supported open video protocol…

[–] Hadriscus@jlai.lu 36 points 3 days ago (1 children)

HDMI, what's that ?

Can the HDMI standard not be implemented in hardware somehow, and then the open source software just talks to that hardware?

It seems ridiculous that you can make a device that works fine under HDMI 2.1 but you can't access it with open source code.

That's the problem. Open source software doesn't work with the NDA. Nvidia does it with an embedded processor and closed firmware, Intel does it with an embedded Displayport to HDMI converter, AMD does it in the driver. Steam uses AMD chips and open source drivers so they can't get it to work.

[–] Petter1@discuss.tchncs.de 3 points 2 days ago

OVFP is needed (Open-Video-Format-Protocol).
Best as interoperable over hdmi, display port and USB-C cables.

[–] OR3X@lemmy.world 39 points 4 days ago (11 children)

But why does the HDMI fourm not want a open source 2.1-compliant implementation? Is it DRM related? I feel like it's DRM related.
