If as I suspect you have set 120 DPI via KDE systemsettings5, you have several alternative options. Via systemsettings5, DPI is set via xrdb's Xft.dpi, which I expect sddm is not utilizing (I don't use sddm, only kdm, kdm3 or tdm). Xft.dpi via systemsettings5 is a user-specific method. You can try other methods.
Start by including in sddm.conf: [X11] ServerArguments=-nolisten tcp -dpi 120
The two alternatives I variously use are the DisplaySize option in xorg.conf* (either /etc/X11/xorg.conf or /etc/X11/xorg.conf.d/50-monitor.conf), and a startup script in /etc/X11/xinit/xinitrc.d/ containing xrandr --dpi or xrandr --fbmm. I would be trying the xorg.conf* approach first, as it seems to take effect during Xorg initialization rather than later.
Another option to try is replacing sddm with a different DM. Thank you, I think this is a good thing to try, makes a lot of sense to me. And you say well, I did set it via KDE systemsettings5. I will first try with the sddm.conf. Will report back when in measure to try.
Cheers!
I've read through this thread and still not sure which graphics card you are using. If it is nvidia, try using the nvidia config utility to change the settings. It's been a while since I used an nvidia card, so I'm not sure of the details, but ISTR using dual monitors in twin view mode satisfactorily. Windows could be dragged from one monitor to the other, and dialogs would appear on whichever was set as default.
