2) Display Properties => Compatibility Tab
3) At the bottom of the tab click "Change high DPI settings"
4) At the bottom of the displayed dialog, in the section "High DPI scaling override", if the check box for "Override high DPI scaling" is selected, select "System" (and not e.g. "System (Enhanced)") in the dropdown.
