Hello there i'm trying to solve this problem that i have for a couple of weeks now.. I have 16:9 monitor and i wanna play game on 4:3 windowed borderless. I have Scaling Mode to full panel and gpu scaling off in the AMD settings and in the profiles too. When i change the desktop resolution to 4:3 it goes full panel without doubt, but when i start the game black bars shows the same when i start any other game or restart my pc, the same will happen, if anyone know any solution please answer
