        We cannot have two standards, that’s ridiculous! We need to develop one universal standard that covers everyone’s use cases.

            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

              There’s some really high bandwidth stuff that USB-C isn’t rated for. You have to really press the limits, though. Something like 4k + 240Hz + HDR.

                That doesn’t even seem so unreasonable. Is that the limit though? My cable puts a gigabyte a second down it so I wouldn’t imagine that would hit the limit.

                  USB-C with Thunderbolt currently had a limit of 40Gbit/sec. Wikipedia has a table of what DisplayPort can do at that bandwidth:

                  https://en.wikipedia.org/wiki/DisplayPort

                  See the section “Resolution and refresh frequency limits”. The table there shows it’d be able to do 4k/144hz/10bpp just fine, but can’t keep above 60hz for 8k.

                  Its an uncompressed video signal, and that takes a lot of bandwidth. Though there is a simple lossless compression mode.

                  It is trivial arithmetic: 4.52403840*2160 ≈ 9 GB/ s. Not even close. Even worse, that cable will struggle to get ordinary 60hz 4k delivered.

          DisplayPort supports CEC.

          From Wikipedia:

          The DisplayPort AUX channel is a half-duplex (bidirectional) data channel used for miscellaneous additional data beyond video and audio, such as EDID (I2C) or CEC commands.

    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.

      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.

          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.

      Is there a reason or way to prevent display port from having so many connection issues specifically on port replicators (docking stations)?

      In corporate environments I find so many times that you plug them up over and over, unplug over and over and check the connection a million times before turning everything off one final time, holding the power button on everything (kind of like an smc reset) and then booting up everything like you originally did and they come up. Is this a result of the devices trying to remember a previous setup or is their an easy way to avoid it?

      I’ve hooked up dozens of them and still ran into issues when a family member brought a setup home to work when they were sick last week.

        We use Dell WD-19 docks. Not sure if you use similar. Updated dock firmware and laptop drivers made a difference for us with connection issues. Sometimes you gotta perform a reset on them to make them behave (disconnect dock power and USB-C and hold power button for just over 15 sec). Sometimes the laptop NVRAM needs to be reset instead (for Dell, disconnect all devices and power while off and hold button for just over 30 sec). Overall, though, no huge issues with DP specifically if the dock and laptop firmwares are up to date. Third-party docks/replicators definitely have way more issues, though.

    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.

          Connected via the display port on my GPU to the HDMI Port on my monitor

          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?

    This sucks as all new TVs use HDMI2.1 for modern features and modern games consoles rely on those for 4k 60Hz HDR, etc.

    So now Valve can’t just make their own home console with Steam OS for TVs directly (and support high-end features at least).

      Linux never ran on the Commodore 64 (1984). That was way before Linux was released by Linus Torvalds (1991).

      I’d also like to point out that we do all rely on non-proprietary protocols. Examples you used today: TCP and HTTP.

      If we didn’t have free and open source protocols we’d all still be using Prodigy and AOL. “Smart” devices couldn’t talk to each other, and the world of software would be 100-10,000x more expensive and we’d probably have about 1/1,000,000th of what we have available today.

      Every little thing we rely on every day from computers to the Internet to cars to planes only works because they’re not relying on exclusive, proprietary protocols. Weird shit like HDMI is the exception, not the rule.

      History demonstrates that proprietary protocols and connectors like HDMI only stick around as long as they’re convenient, easy, and cheap. As soon as they lose one of those properties a competitor will spring up and eventually it will replace the proprietary nonsense. It’s only a matter of time. This news about HDMI being rejected is just another shove, moving the world away from that protocol.

      There actually is a way for proprietary bullshit to persist even when it’s the worst: When it’s mandated by government.

      Why? Most software wasn’t proprietary before companies realized they could make more money at your expense (not all the profit is going into making a better product).

      If given the choice of an uncomfortable dormitory or a comfortable jail, at least the residents can improve the living areas in the former.

        Parent is right though. Unix being proprietary is why the GNU project was started, and why the Linux kernel and BSDs rose above.
