Me again... surprised no one has answered. After waiting for a reply and not getting anything I decided to try a few things. First I tried downloading the new version, 18.2.2, in hopes the problem was fixed. It wasnt. Then I tried to roll back my driver, but I could only roll back to 18.2.1. Then I tried downloading and installing my last version, 17.12.2 which surprisingly also didnt work, which makes me think the problem was related to the AMD Radeon Settings App. So I tried uninstalling the driver, then reinstalling the latest version 18.2.2, which led to a different problem.
When I started up finally my screen was now too big, where your border goes off the side of the screens. So I tried using the app to fix the border again. After a restart I had the same problem, another black border Then I got clever and tried offsetting my screen size so it would be correct when logging in, which worked 99%. Normally I need a 6% HDMI scaling, but if I set it to 3% where its slightly too big, then I restart, the size is more or less where it should be. Kind of annoying but I figured Id let people know the work around I discovered until an actual fix is made, though still unsure what happened to cause the problem. My only guess still is something changed between updates 17 and 18 and my monitor doesnt approve.
