Font DPI in kde should be set to 96 by default, but it's calculated automatically which causes issues

@piotrus3g Hi, I’m on TW/GNOME here with Nvidia and all fine DPI wise.

Perhaps a read here? https://download.nvidia.com/XFree86/Linux-x86_64/535.104.05/README/dpi.html

I have three (24" 1920x1080) screens here and see;

xdpyinfo | grep -B1 dot

  dimensions:    3840x2160 pixels (1016x572 millimeters)
  resolution:    96x96 dots per inch

So what did you have to do to set the DPI?
