Problem
The first time I installed the Radeon drivers on the system, it was fine. At some point I decided to remove the (same) drivers, and re-install them. Now, the maximum resolution with Radeon software is up to 1050p @ 60Hz. The option to either increase resolution to 1440p or refresh rate to 75Hz is gone. I can now only get back to 1440p (but still at 60Hz) by uninstalling the Radeon drivers and using the Windows built-in display driver.
I have even tried DDU running in Windows safe mode, but the PC still returns to a 1050p @60Hz resolution as soon as the aforementioned Radeon drivers are re-installed.
Is there something else I could do? I would much appreciate any help available.
