HDMI Forum Rejects Open-Source HDMI 2.1 Driver Support Sought By AMD
www.phoronix.com

For three years there has been a bug report around 4K@120Hz being unavailable via HDMI 2.1 on the AMD Linux driver.

The wait continues…

    This really bothers me. Closed standards locked behind a licensing fee may as well not be standards at all, in my opinion.

      I don’t understand why any hardware uses HDMI anymore anyway, what does it have that displayport doesn’t?

        Decades of being the standard in a/v. That’s like asking, why don’t we get rid of gas stations and just install electric chargers? Well, everybody’s got gas powered cars.

          AV things sure since they stick around longer, but computers? When was the last time you saw a high end GPU with VGA or DVI? And they already usually have mostly DisplayPort with just one or two HDMI ports

            Well, I wasn’t referring to that ecosystem. That ecosystem is already on display port. The reason HDMI is so prevalent is because it’s the standard in audio-visual equipment. Why would I talk about computer equipment when it’s not the standard there?

            The point still stands. Everybody has equipment that has HDMI, and to phase out that standard in equipment going forward is phasing out equipment people already own.

        Feature-wise probably next to nothing, and it’s usually behind one or two generations in terms of bandwidth. HDMI is often the only port available on TVs though, so GPU makers likely can’t afford to just leave it out.

          They should anyway. New tech TV’s are all smart these days and the dumb ones are made for two decades ago. At this point we are better off with a PC monitor and separate speakers. Built in speakers are shit seemingly as a requirement. I use a video port switch for extra inputs without needing to use the on screen menus or just running out of built in ports.

          Your info is outdated. DP 2.0 is 80 Gbps can do 4K@240hz without display stream compression. It can do up to 16K@60hz using DSC.

        CEC (technically I think displayport could support it, but generally isn’t implemented) and ethernet up to 100Mbps.

    Alright AMD, just remove HDMI from your graphics cards and be done with it 🤷 . Fuck the HDMI forum.

      As much as I want them to give HDMI the middle finger I don’t think they have enough leverage in the GPU market to pull such a bold move off.

    So I see people on the phoronix forums complaining that this is a bad thing because they have TVs which are HDMI only. From what I read, the HDMI 2.1+ spec is only needed to support extreme cases like 4k@120Hz and above. So my question is how many people are there who have a TV old enough to have no display ports but be of that outrageous specification.

    Edit : it seems I am mistaken in thinking that new TVs have display port.

      As far as I know no consumer TV has Display port.

      I bought a TV maybe 2-3 years ago that supports 4K@120 and it doesn’t have a display port, only HDMI.

      I’m using a recent 42" LG OLED TV as a large affordable PC monitor in order to support 4K@120Hz+HDR@10bit, which is great for gaming or content creation that can appreciate the screen real estate. Anything in the proper PC Monitor market similarly sized or even slightly smaller costs way more per screen area and feature parity.

      Unfortunately such TVs rarely include anything other than HDMI for digital video input, regardless of the growing trend connecting gaming PCs in the living room, like with fiber optic HDMI cables. I actually went with a GPU with more than one HDMI output so I could display to both TVs in the house simultaneously.

      Also, having an API as well as a remote to control my monitor is kind of nice. Enough folks are using LG TVs as monitors for this midsize range that there even open source projects to entirely mimic conventional display behaviors:

      I also kind of like using the TV as simple KVMs with less cables. For example with audio, I can independently control volume and mux output to either speakers or multiple Bluetooth devices from the TV, without having fiddle around with repairing Bluetooth peripherals to each PC or gaming console. That’s particularly nice when swapping from playing games on the PC to watching movies on a Chromecast with a friend over two pairs of headphones, while still keeping the house quite for the family. That kind of KVM functionality and connectivity is still kind of a premium feature for modest priced PC monitors. Of course others find their own use cases for hacking the TV remote APIs:

      TVs don’t have DisplayPort. I just bought a new TV, none of the options I looked at had display port.

    This destroys any chance of Valve making an Xbox-competitive home console with SteamOS :(
