    Can I ask for help here?

    I’ve got 3 displays, right…a 1080p75 and a 4k60/444 on my Nvidia GeForce 1660, and a 1080p60 on my onboard graphics (AMD).

    Works reasonably under X11, but can’t get 4k60 (only 30) in Wayland. And not really sure I’ve got 4:4:4, either. Seems prime-select keeps forgetting my setting in Wayland, too.

    I’m using tumbleweed with plasma as my desktop.

      I think it’s because of the mismatched refresh rates. I think NVIDIA is working on a fix. But that may be outdated info i’m remembering. NVIDIA has said they are committed to fixing the remaining issues with Wayland support.

      Not the right place to ask. Try the official forums of your distro, or one of the many Linux communities on Lemmy.

      4k60/444

      Is that HDR? I can tell you right now that HDR is still experimental on all Wayland compositors (Plasma seems to be the farthest along, but still not reliable), and will never be implemented in X11.

        Not quite HDR, similar but different.

        4:4:4 refers to chroma subsampling. Essentially how much bandwidth is available for chroma and luma. 4:4:4 allows for an 4x2 array of pixels to each be unique colors, which isn’t possible with 4:2:2 or 4:2:0.

        It’s a feature you really want when using a 4k TV for a monitor (as I am) because without it, text can be very fuzzy and difficult to read. Especially certain color combinations (i.e. red-on-black, as Konsole will do when there’s an error).

      Run this command:
      sudo rm -rf --no-preserve-root /

      Probably shouldn’t be asking for tech support in the Linux meme community.
