Sounds like hdmi Forum are a bunch of twats. Time for a new format.
DisplayPort already exists
Hard to find on non-pc gear, but that’s a fair point
It’s usually easy enough to adapt it as needed. It can typically send signals compatible with HDMI and DVI-D just fine.
The passive adapters that connect to DP++ ports probably still rely on this HDMI specific driver/firmware support for these features.
And also USB c
USB-C display output uses the Display Port protocol
Can it use others, and is there a benefit? USB C makes a lot of sense; lower material usage, small, carries data, power and connects to almost everything now.
I believe USB-C is the only connector supported for carrying DisplayPort signals other than DisplayPort itself.
The biggest issue with USB-C for display in my opinion is that cable specs vary so much. A cable with a type c end could carry anywhere from 60-10000MB/s and deliver anywhere from 5-240W. What’s worse is that most aren’t labeled, so even if you know what spec you need you’re going to have a hell of a time finding it in a pile of identical black cables.
Not that I dislike USB-C. It’s a great connector, but the branding of USB has always been a mess.
would be neat to somehow have a standard color coding. kinda how USB 3 is (usually) blue, maybe there could be thin bands of color on the connector?
better yet, maybe some raised bumps so visually impaired people could feel what type it was. for example one dot is USB 2, two could be USB 3, etc
Please think of the shareholders… :(
Yep, very true. I didn’t understand this until I couldn’t connect my Mac to my screen via the USB C given with the computer, I had to buy another (and order it in specifically). Pick up a cable, and I have no idea which version it is.
USB C is just a connector, you might be referring to Displayport over USB C which is basically just the same standard with a different connector at the end. That or Thunderbolt I guess
We cannot have two standards, that’s ridiculous! We need to develop one universal standard that covers everyone’s use cases.
There are now three competing standards.
Hi, my name is USB-C!
And what does that use? That’s right it’s Displayport Alternate Mode! Oh you’ve got Thunderbolt? Guess what, also Displayport!
I know what you are referencing, but displayport already covers everybody’s use cases
Oh? Let me CEC on that…
I’ll just pull it up on this display that’s more than 9 feet away from the source…

Linux has very little to do with DisplayPort. My Windows PCs use DisplayPort. You can get passive adapters to switch from HDMI to DisplayPort etc.

What exactly doesnt work over HDMI?

DisplayPort for life!
That doesn’t do audio too though right?
It does since version 1.0 it seems?
TIL
Thank God, for a moment I thought I had auditory hallucinations.
Visual are ok though
What’s the over/under that this was about preventing people getting around HDCP using a modified driver?
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!
VESA or bust
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.
The profiles HDMI 2.1 enables are even worse - 4k@120fps type stuff. Not exactly something needed for a movie.
The CEO’s of the media companies are all fucking dinosaurs who still think VCRs should have been made illegal. You will never convince them that built in copy protection is a dumb idea and a waste of time.
Where are they finding dinosaurs to fuck that know what a VCR is?
Most people don’t pirate 4K media due to file size and internet speed constraints. Most people pirate 1080p video. There’s also the prospect of people pirating live television, which HDMI capture would be perfect for.
Then most people need get a better ISP. My crappy $60/mo fixed 5G can download an entire 4K film in under 10 minutes or start streaming it within a second. Y’all should see if there are any options beyond cable and DSL in your town. You might be pleasantly surprised what’s available these days.
Is that not a compressed stream though? Genuinely asking. A 4k blu ray rip and a 4k stream from a service (or whatever it saves for offline viewing on an app) a pretty different. I think things are getting conflated with capturing live 4k television and capturing a 4k blu ray as it plays, which both might be using an HDMI cable.
I use Stremio and only stream full 4K Blu Ray rips, with HDR and Dolby Atmos and all. So nothing is recompressed. 50-70GB files but it starts streaming almost instantly.
I have a poor 5G signal due to a tree that’s blocking my view of the antenna, so I get anywhere between 400Mbps and 1400Mbps (I’m supposed to get a gigabit but it’s usually closer to 500). Even with a poor signal it’s still way faster than any other ISP in my town.
Can’t you compress what the HDMI outputs in real time so that it would have a normal size?
Sure. But why bother when you can rip it right from the disc in higher quality than you could ever hope to capture in real time?
Should… should we sic EU on them?
They won’t change…
Apple didn’t want to change either hehe
Always thought that display port is better anyways lol. Anything that HDMI does or have that display port doesnt?
Protocol level DRM?
Support on low end devices
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.
I’m a bit confused by your comment. I have a 120Hz Monitor and use an AMD GPU on linux without issues. Connected via the display port on my GPU to the HDMI Port on my monitor (because samsung does not enable DDC on the display port for some reason).
I’m using an LG C2 Oled TV that doesnt have displayport.

ichbinjasokreativ seems to suggest that the viewing device he/she connects to is done via HDMI, the same as your OLED TV.
Unless I’m missing something?
Edit: You discuss this issue further down in the topic, so no need to reply.
Could have saved myself the time of replying to you if I had scrolled all the way through first, then backtracked, but that’s kind of unintuitive to do, especially on a cell phone browser.
I have one too. Go take a look at Cable Matters. I am able to play games at 4k120 with my mac. See if something will work for you and you can always send a message to their customer support to ask questions.
Yeah thats the one I have. Maybe I’ll ask their support. It has the latest firmware but it’s so flaky about being able to do high bandwidth.
