KDE Plasma DE on 4K UHD TV

So I installed Archlinux with KDE Plasma DE using the archinstall script.  Everything is working with one minor issue.  Because my TV is 4K to make it meet my needs I have chosen to set the Display Configuration resolution to 1920x1080@60.

The display looks good at this resolution but now my login screen still is too small as if the Display configuration resolution doesn't apply to the SDDM login screen.

I thought the synch option on the Login Screen settings page would solve this but it does not.

Any ideas on how to fix this?

BTW, keeping the resolution at 4K and setting the scale factor to 200% has way too many issues to discuss in this post.

Re: KDE Plasma DE on 4K UHD TV

I stumbled across this wiki entry:
https://wiki.archlinux.org/title/SDDM#Enable_HiDPI

All I did was create a file /etc/sddm.conf.d/hidpi.conf with:

[Wayland]
EnableHiDPI=true

[X11]
EnableHiDPI=true
ServerArguments=-nolisten tcp -dpi 160

I played with the dpi number to get it right for me.

BTW, I only tested X11 on my system.

@jfabernathy: Thank you! I am in the same boat, this worked. There are dozens of us, dozens.
