assuming we have two monitors connected, both at 1920x1080
cgorigin --origin -1920 0 # positions the second monitor to the left of the main display
cgorigin --origin 0 0 # positions the second monitor to the right of the main display
cgorigin --origin -1920 1080 0 # positions the first monitor below the second display
