    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).


  • 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.
