I have an Asus Notebook X555DG.
Processor: AMD A10-8700P Radeon R6, 10 Computer Cores 4C+6G 1.80GHz
Installed RAM: 8.00GB
Windows 10 -64bit
Graphic Card: Radeon R6 M3400X 2GB
I had a comparable issue to this thread: Radeon Settings Are Not Currently Available - A10-8700P APU 17.12.2 . However it hasn't quite panned out for me in the same way.
I have previously done multiple clean uninstalls with DDU, used the most recent drivers from the AMD website, as well as also attempted to use the ones recommended by Asus support.
The most recent recommendation being to install the Asus Chipset and thereafter using the Radeon minimal setup to update the graphics card to the most compatible. This puts me in the place, where I now get the prompt "Radeon Settings are currently not available. Please try again after connecting AMD graphics." and my device manager shows an issue with graphics and chip.
