I am not sure if you can read this new Adrenalin 2020 20.1.4 GUI but if you look at this screenshot.
Turning on "Enhanced Sync"
Disables the "Wait for Vertical Refresh Button" and darkens it and sets it to "Off unless applications sepcifies".
Which I guess is an indication that you should turn off in game Vsync maybe ...
The above is the best GUI scaling I can get on my 4K display with Windows 10 Pro that will fit on one screen, sorry if it is difficult to read.
