The default settings for powering off the monitor and PC under Microsoft Windows 10 are to turn off the screen after 10 minutes with no keyboard nor mouse activity when the system is plugged into a power outlet and to put the system to sleep when plugged in after 30 minutes of no keyboard nor mouse activity. You can view and modify the settings by right-clicking on the desktop in an area unoccupied by any shortcut and selecting Display Settings, then clicking on Power & Sleep.
