I have a Radeon RX 570 GPU with the ASROCK B450M Pro4 and Ryzen 9 5900 CPU. I just added a new monitor the 27 inch LG 4k HDR. I've tried multiple times to install the AMD Radeon Software Adrenaline 2020 edition and it always fails.

Has anyone encountered this issue? Can you confirm this should work with this MB?

It is possible there is something corrupted in the GPU settings/driver. There is a free tool called DDU, Display Driver Uninstall, that attempts to completely remove a display driver so the system appears clean. Often that allows the proper driver package to be installed. It's best to be boot into safe mode for DDU to work properly.

The DDU tool can be found here: https://www.wagnardsoft.com/
