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

What about shipping an adaptor? DP to HDMI for the transition?
Can dp even translate to HDMI with a "dumb" adapter?
DP can do HDMI natively.
HDMI needs an active adapter to support DP.
yes, i have a dp to hdmi 2.1 cable that cost like 35€. it works fine except each time i get up from my chair the screen flashes white. and no VRR.

Wha... how? What?

Yes, DP converts to HDMI natively. But because HDMI has so much proprietary BS built in, going from HDMI to DP requires an active adapter which strips out the proprietary BS.

Good point!
I agree with the sentiment but we're dealing with a chicken and egg problem. If no TVs have DisplayPort, who would buy a console that can't be used with their TV?
TVs are starting to come with DisplayPort already in the form of USB-C alt mode.

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

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 😅

We need more DisplayPort in the world - and better support for multi-monitor setups under Linux.
What are you missing in multi-monitor setups under Linux?
Every time I plug a second monitor into my Linux PC (Mint), both screens start blinking on and off. Sometimes Win+P works, sometimes it doesn't. I've asked in the Discord, I've tried arandr. Nothing works.

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

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.

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.
Its fully DRM related.
My guess is if it’s open source it’s more easily cracked.
Likely moreso that they're facing pressure from other competitors in the industry that see Steam and open source in general as a threat to their business model. The HDMI forum is made up of industry leaders, and naturally Microsoft and Sony are there.
They've been refusing open HDMI 2.1 since 2017. I don't think that being afraid of Linux becoming the dominant gaming platform plays a role here; it's more likely that they're afraid people might find new ways to get at protected content.
Ive never had using HDMI prevent me from enjoying pirated media, so Ive always been confused about what sort of drm a TV is looking for.
It’s more of a barrier for people who are pirating media, not the ones consuming that pirated media.

Maybe a dumb question… if I used a DisplayPort to HDMI 2.1 adapter, would I get 4K at 120Hz on the Steam Machine and my LG CX tv?
Depends on the adapter and source. You may find issues when playing HDPC protected content if you buy a low quality adapter.

HDMI, what's that ?
sent from my DisplayPort monitor
Not all software available on Linux is open source. NVIDIA drivers for example. Hell, most of the games on Steam are closed source.
So, is it just a matter of principle on Valve and AMD's part that they only want to ship with fully open source drivers?
I'm not technically knowledgeable enough to understand why you can't just make the HDMI 2.1 part of the driver code closed source and the rest of the graphics drivers open?
Modern specs are complicated. I vaguely remember something about a cryptographic key the driver needs to be signed with to successfully complete the handshake to enable all display options between the computer and display.
Not entirely unwarranted either, an unexpected amount of voltage on an unexpected pin because the driver / hardware is misconfigured damaging your TV would suck. (Still sounds like the Forum is being a dick about it though.)
