I had been having scaling issues with my vega 64 and my LG 4k tv but a few updates ago resolved the issue and allowed my screen to properly scale but that gold age ended with driver 19.2.1. I am not losing 1/4 in (6-7mm) all the way around my desktop with no scale adjustment to be found. Why, oh why, does AMD fix a problem only to give it back?.
Update 19.2.2 with clean install failed to resolve overscaling issue.
