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…

    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.

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

        Your info is outdated.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.
