Not sure what's going on today, but I cannot get the Radeon software to play nice.
Booted up my PC to find Windows in 1600x1080 resolution (instead of 3440x1440). No options above this resolution. Restart, same. Update drivers, same. Update Windows, same. Then tried rolling everything back. Also tried reinstalling the display drivers. No matter what I did, the Radeon software was adamant that the display can't support any higher resolutions.
So I went the nuclear option and reinstalled Windows. Suddenly, everything is fine. Until I installed the Radeon software again. Same problem.
At a bit of a loss on this one. I can update my drivers through Windows. But the moment I install Adrenalin, it's back to 1600x1080, with no way of overriding it.
Uninstall all Radeon drivers as normal thrugh control panel and device manager (check delete driver) then run DDU and use the shutdown options I think under installing new graphics card. Unplug from the net so Windows cant load its generic drivers and then install the new Driver.
