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.

The HDMI forum can go fuck itself

[–] Petter1@discuss.tchncs.de 6 points 12 hours ago

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…

[–] Petter1@discuss.tchncs.de 4 points 12 hours ago

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

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

[–] echodot@feddit.uk 2 points 7 hours ago* (last edited 7 hours ago)

As much as I agree I think it would have been a bad move for them to do that. The devices success is already highly dependant on its price, which is still in flux as far as I understand, there is no reason for them to make the decision even more difficult.

[–] pewgar_seemsimandroid@lemmy.blahaj.zone 40 points 1 day ago (1 children)

Displayport is better anyways.

[–] NutWrench@lemmy.world 26 points 1 day ago (1 children)

Yup. Especially since "smart TVs" that are WiFi connected can spy on your HDMI connection. Samsung, LG and Visio were caught doing it.

After all the shit I've seen and heard about the creepy shit smart TV manufacturers get up to I am never ever connecting a smart TV to the internet in my home.

[–] XeroxCool@lemmy.world 3 points 15 hours ago (1 children)

I didn't connect my free Roku TV to the new wifi, and suddenly the remote works like shit. Turns out, it's a wifi remote that would rather not use infrared and the infrared receiver has been slightly blocked this whole time.

The way to set it up without connecting it to wifi is very hidden. I had to look it up after because I couldn't figure it out. I fucking hate smart tvs.

[–] echodot@feddit.uk 2 points 7 hours ago (1 children)

I hate the Wi-Fi remote thing. My TV has a Wi-Fi remote and it runs off of AA battery and they last about 4 days and then run out. If I hadn't replaced them with rechargeable ones they would have probably had to open a new landfill site just for my old batteries.

[–] XeroxCool@lemmy.world 1 points 41 minutes ago

My roku has an internal rechargeable battery and lasts months. But what's infuriating is I read up further and found it doesn't actually use my wifi network. It's direct to the TV. So why wouldn't it work without internet? Insane.

[–] Blackmist@feddit.uk 10 points 1 day ago (1 children)

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.

[–] count_dongulus@lemmy.world 66 points 1 day 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 1 day ago* (last edited 1 day 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 1 day ago (2 children)

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

[–] echodot@feddit.uk 1 points 7 hours ago

Oh yeah, and and they would mostly be terrible, except one brand no one has ever heard of but, it's apparently a big name in China, and called something like Zloks would inexplicably be the king of that particular niche product.

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

[–] azvasKvklenko@sh.itjust.works 29 points 1 day ago (2 children)

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

[–] echodot@feddit.uk 1 points 7 hours ago

It might be possible to get into output wirelessly, it has a dedicated radio for video output so presumably if you just stuck an adaptor into your TV you could just cast to it. Could be quite a nice setup if you wanted it to be able to connect to both your computer in the study and your TV in the living room.

[–] LorIps@lemmy.world 27 points 1 day ago (4 children)

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

[–] azvasKvklenko@sh.itjust.works 2 points 20 hours ago

Yes, but forget about VRR unless you want to flash a custom firmware and with that the adapter is finky as hell. I use one for 2 years now. It kinda works

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 1 day 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 1 day ago (15 children)

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

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

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.

[–] BreadstickNinja@lemmy.world 164 points 2 days ago (8 children)

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

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

[–] ShinkanTrain@lemmy.ml 80 points 2 days ago

Sony would probably create a proprietary standard before they'd switch to displayport.

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