There are two settings in Plasma 5 regarding DPI. Old setting I still use is 
with Fonts. "Force dpi for fonts." I use 140 dpi for 1080p 15" screen. I use a 
little les than 148 dpi, cause I have another 22 inch external display and its 
gets to big there with 148 dpi.

Second is in display settings (kscreen). "Scale display" or something like 
that in english. I think I tried to use it, but I had an issue with it, so I 
am still just using the font size scaling mentioned above. It seems you can 
set a different dpi for different screens tough so I think I will have a look 
at it again some day. Also it scales all elements not just fonts.

I still dream on autodetecting dpi and automatic configuration for each 
display. I.e. the underlying gui toolkit just using points. But well its a 
complex issue and there have been quite some blog posts by KDE devs about 
proper high-dpi support. And the screen scaling is what they came up with.
