On R21 and 4K monitors (Win & Mac) it's hard to use scale 100%. (Small UI, Small Font)
So I always use a 150% scale. And octane LV is also 150%. It is not real resolution.
At first I thought it was a problem with C4D.
But C4D SDK includes a way to solve this problem.
It's difficult, but hopefully it will improve.
C4D Dev says
SDK - "The user area (that is used by plugins - like the PV - to display custom output) contains functions to transform from global or screen coordinates to local coordinates as well as a method returning the pixel ratio."

Also my computer has several programs. This setting is not useful for each program.
Fonts are still small on 4K monitors. Please test on 4K Monitor.
HiDPI Scaling must be supported, such as Octane for Houdini and Blender.
I hope this feature is added.
