how to have black bar after changing resolution to lower resolution?

Hi,
I am having hard time concentrate after I upgraded my screen from 22'' to 27'', my productivity is extremely low, I can't concentrate on the task at hand, I changed my monitor resolution from 1440p to 1080p but it only stretch the pixel, I just want to have black bar when I switch to 1080p so I can concentrate on things I want to do easily rather than trying hard to ignore the irrelevant things on the screen that 1440p and 27'' screen show up compare to my old 22'' and 1080p screen
Thanks

I found it, I have to go to Radeon setting and turn off scaling, now my productivity is now back to normal, if anyone is using big size monitor, try to use different resolution, turn off scaling and see if it increases your productivity.
Thanks
