If mode reports resolution 1920x1080, but the screen is scaled by 2, then we want to show the output rectangle in KCM to be 3840x2160 so that it's in the correct ratio. If you put the scaled output next to a HiDPI output (3840x2160) in the KCM the rectangles should both be the same size. Hence the multiplication.
