idk man, there r some options like GPU scaling, Scaling Mode(Preserve aspect ratio, Full Panel, Center), I tried all the settings, but no hope. and also there should be an option for Custom resolution in my amd adrenaline soft, but there's isn't any maybe that's what causing all this trouble, i have amd vega 8.Probably not but in the Graphics Utility see if there is an option to turn off Maintain Aspect Ratio.
actually I can't disable/enable Preserve aspect ratio, I can only switch between those three options,Preserve aspect ratio - turn that off and see if it will stretch now and fill in those black bars.
Its like:actually I can't disable/enable Preserve aspect ratio, I can only switch between those three options,
nope, not working, i'll try to do some research on google about this problem, anyways thanks..Full Panel maybe?
