Hi all.

Happy KDE Plasma user for a long time and I generally love the desktop experience. But I do have one small issue.

At work, I have 2x 4K displays. connected through a Dock. But in Plasma it’s only able to give me around 1080p resolution on both of them. In contrast, the display manager SDDM and TTY displays 4k on each fine.

So am I missing a trick to get the max resolution in Plasma? My install is Arch Linux, kernel 6.4.12, Plasma 5.27, Wayland session.

I did install the displaylink AUR package, as I thought it might be the dock limiting the video output, but it isn’t as TTY and SDDM seems to display it correctly.

Happy to hear any thoughts and any ideas. :)

EDIT: The screens turn on and work fine with 4K resolutions in a Plasma X11 session.

    So, a small update here.

    Switching to Xorg, seems to get both monitors capable of running in 2160p mode. So it seems to be a Plasma Wayland limitation.
