Bug Description
I have to 4k monitors.
15" on the dell xps 3840/2160/60
40" philips external BDM4065 3840/2160/30
Obviously i need different scale factors to use them properly.
This feature DOES NOT WORK.
It seems the scaling is not handled separately per monitor as the UI suggests.
The fractional scaling also does not seem to work. any change to the scaling ends seems to be rounded to full.
Which meens a compromise scale of 125% is effectively 200% on the large monitor.
I havent found any config which would make this useful.
So basically when I use the external 40" I cannot use the builtin anymore
without an external fresnell magnifier lens (which I dont have ;)
