R9 390X Blackbars on CS:GO Issue!?

Hi guys,


I know this question it's been up in the community since last years but after all threads i've read and all my attempts on trying to remove the black bars in CS:GO i couldn't find anything to solve it.

Right now i'm running the newest version 17.3,what i have to do to remove them?

Does my GPU has a problem or something?


Thank you!
