Thanks for the report!

This isn't supported on X11, and we're not planning to. The Wayland session
already has this feature, I'd suggest to consider moving to Wayland.

Monitor Scaling Issues

All screens use scaling of 2 with no option to change. Top screen is FHD,
bottom is QHD.

This is a problem in 5.12.0 as well. I have a Dell XPS 13 (9360) Developer
Edition with the QHD (4k) display. DPI is 144, I set scaling to 2. When a FHD
(1080p) monitor is connected, the external monitor is also scaled at 2.

There is no option in the Displays Settings Module to change scaling
per-display. This would be a major quality of life improvement for those who
use docks and external monitors.

I have attached a screenshot of the issue. The top monitor is the FHD monitor
scaled at 2.

KDE Plasma Version: 5.12.0
KDE Frameworks Version: 5.42.0
Qt Version: 5.9.3
Kernel Version 4.13.0-32-generic
OS Type: 64-bit

Thanks for the bugreport!

Have you tried the mechanism described here:
http://doc.qt.io/qt-5/highdpi.html#high-dpi-support-in-qt ?

(It's not reflected in the KScreen UI, in that sense, the bug is valid. You may
be able to work around it, though.)
