I play 1600x900 full screen resolution in CS:GO and it re-sizes my second monitor to the same resolution (1600x900) leaving black bars on both the sides and top/bottom of my monitor, but if I tab out it goes back to the native resolutions on both monitors. I would like to keep my second monitor at its native resolution (1680x1050) so is their anyway to prevent that from happening or am I stuck with it? My second monitor doesn't have any scaling options in the menu.
Primary monitor native resolution: 1920x1080
Second monitor native resolution: 1680x1050
Primary monitor native resolution: 1920x1080
Second monitor native resolution: 1680x1050
