I do not really have a body for this. I was not aware that this is a thing and still feel like this is bs, but maybe there is an actual explanation for HDMI Forum's decision that I am missing.

Fuck you HDMI Forum

[-] mp3@lemmy.ca 227 points 3 days ago

I really hope we'll see TVs with DisplayPort one day.

[-] Kevlar21@piefed.social 94 points 3 days ago

I think I’d like DisplayPort over a USB-C connector. It seems like this might be an easier sell too, since the general non-techy populace is already used to everything going to USB-C (thanks EU). Maybe one day we can actually just use the same cable for everything. I realize that not all USB-C cables are equal, but maybe if TVs used USB-C, we’d see more cables supporting power, data, and video.

[-] IMALlama@lemmy.world 50 points 3 days ago

Display port over USB-C is totally a thing. With things like USB-PD USB seem to be getting dangerously close to becoming the standard for everything. The cables are a wreck though and are way too hard for a layperson to tell apart.

[-] CosmicTurtle0@lemmy.dbzer0.com 22 points 2 days ago

I'm a very technical person and I can't tell them apart.

Is there a symbol?

[-] Chronographs@lemmy.zip 42 points 2 days ago

It’s pretty simple and straightforward, all you have to so is buy the cable and a professional cable tester to see what specs it’s actually in compliance with

Don’t worry, I’m sure when USB 4 releases, they’ll retroactively change the names of USB 3.2 Gen 1 and USB 3.2 Gen 2 to “USB 4.3 Gen 0.01” and “USB 4.3 Gen 0.02” respectively. Then USB 4 will actually be named “USB 4.4 Gen 5” just because.

And none of the cables will be labeled, nor will they simultaneously support high power delivery and full data speed. We’ll need to wait for “USB 4.4 Gen 4” for that, which is when the old standard will get renamed to “USB 4.4 Gen 3.5” instead.

If you want change you got to direct your comments to the HDMI forum. Here we can talk about it forever and if they never see anything they won't change. I sent the following email to: admin@hdmiforum.org

Dear HDMI Forum,

I was recently saw the news that the HDMI forum was blocking open source implementations of the HDMI 2.1 specifications and I want to express that I really believe this is a bad idea. I hope the HDMI Forum will consider allowing it. I can't say I understand what the concern is or the reason for blocking it but I really doubt that whatever issue is envisioned will actually come to fruition, instead I believe that allowing open source implementations will be beneficial for adoption of the standard and since if I understand correctly the licensing fees are based on hardware sold so having open source code will of course not exempt anyone from HDMI licensing rules.

Thank you so much for your consideration,

(Name)

Maybe it's not perfect (I already wished I worded one sentence better) but I think what matters most is just trying your best and using your voice whenever you can. Be sure to send your email too, the more they receive hopefully the higher the chances that this works but of course be sure to use your own wording, I just put that here for an example.

[-] spicehoarder@lemmy.zip 20 points 2 days ago

I'm at the point where I think it would be easier to switch to display port

[-] Crozekiel@lemmy.zip 8 points 2 days ago

I can't find TVs with display port, probably because of "big HDMI". :(

[-] muusemuuse@sh.itjust.works 10 points 2 days ago

Fun fact: DisplayPort can carry hdmi signals. So you can connect a cheap cable with DP on one end and HDMI on the other. The only catch is it goes DP->HDMI, not the other way around.

[-] brisk@aussie.zone 4 points 2 days ago

Hilariously this is the easiest way to get HDMI-CEC support on a (Linux) PC

maybe there is an actual explanation for HDMI Forum’s decision that I am missing.

HDMI has never been an open standard (to the best of my understanding anyway). You've always needed to be an adopter or a member of HDMI forum to get the latest (or future) specs. So it's not like they've just rejected a new idea. The rejection is fully consistent with their entire history of keeping the latest versions on lockdown.

Standards organizations like HDMI Forum look like a monolith from the outside (like "they should explain their thinking here") but really they are loosely coupled amalgamations of hundreds of companies, all of whom are working hard to make sure that (a) their patents are (and remain) essential, and that (b) nothing mandatory in a new version of the standard threatens their business. Think of it more like the UN General Assembly than a unified group of participants. Their likely isn't a unified thinking other than that many Forum members are also participants in the patent licensing pool, so giving away something for which they collect royalties is just not a normal thought. Like.... they're not gonna give something away without getting something in return.

I was a member of HDMI Forum for a brief while. Standards bodies like tihs are a bit of a weird world where motivations are often quite opaque.

Okay not publishing the spec is still the same, but something else is new nonetheless.

AMD is an adopter*, they have the spec and they implemented a driver for 2.1 intended to be open sourced in Linux. But they were still blocked from publishing it. For HDMI 1.4 that wasn't an issue yet from what I've found (though it's always hard to search for non-existence). Open source implementations of HDMI 1.4, even in hardware description languages, seem to exist.

*you can search for "ADVANCED MICRO DEVICES" here to confirm for yourself

Can we just do display port then?

Can you name or link some models? I'd like to consider my options but haven't found any yet.

That's why HDMI needs to die and display port needs to take over. The TV industry is too big for that to happen of course. They make a shit ton of money off of HDMI

[-] cmnybo@discuss.tchncs.de 69 points 3 days ago

AMD should remove the HDMI port from all of their GPUs as a nice F.U. to the HDMI forum. They shouldn't be paying the licensing fees if they are not allowed to make full use of the hardware.

[-] dohpaz42@lemmy.world 31 points 3 days ago

There would be uproar, but like the audio jack on phones people would come around. All it would take is one big enough company to pull it off, and the rest would follow.

For now, but DP and specially DP over USB-C is becoming gradually more popular for computer hardware, someone paying 400 euros for a GPU doesn't mind paying 10 bucks extra on an adapter if they have an HDMI monitor. But most monitors nowadays come with DP anyway.

Yes, this isn't new but it's resurfacing thanks to the Steam Machine. Basically (off my memory), part of your title is accurate: AMD did create a FOSS driver with HDMI 2.1 which does not violate HDMI forum requirements, but the HDMI forum still vetoed it. I don't know if it would necessarily "disclose the specification" as the first part of your title suggests, but I didn't dig into the details enough to say for certain.

Basically a dick move by HDMI. Maybe Valve can push their weight on this, we'll see.
