I've got a screen on 16:10 resolution and when I try to enable "GPU Scale" settings I can't find it on the AMD applications.

The screen has a 16:10 (1900x1200) resolution and the resolution is locked to a native 16:9 (1920x1080) resolution.
I can't find the GPU Scale settings on AMD Catalyst and AMD Radeon Settings.
GPU : AMD Radeon R5 330    

OS : W10
CPU : Intel Core I5
