Created attachment 181453 [details] systemsettings application shown screen settings The systemsettings application has a module to configure the display configuration. This includes position, resolution, orientation, refresh rate and replica. The scaling can be only configured globally. It would be really nice to make the scaling settable for each display. Currently, the user has to use the command line utility "xrandr" to archive this, like: xrandr --output LVDS-1 --scale 0.8x0.8
Per-screen scale already exists, but it's a Wayland-only feature. Backporting it to the Plasma X11 session isn't possible for technical reasons. If good monitor support is a priority for you, I'd encourage the use of the Wayland session! It's really much better for fancy monitor usage.
