Show me a screenshot of what your display settings look like please.

I couldn’t even find a place to do it. Only config for display scaling applied or to all monitors. And it requires a restart of kde every time. So either large external screen became unusable or the small laptop screen.

I haven’t used Xorg in years. All my problems are in Wayland.

Great, now please fix per monitor scaling. 4k laptops are unusable when connected to large 4k screens. I need no scaling on large external screen and about 175% on laptop’s 16".
