I think that the way most projectors including the SONY 4K ones, is that if they are table mounted right side up at the height of the bottom of the screen, then there is no additional user vertical lens shift needed, as the default position of the lens relative to the image source is set for this common situation. Likewise if the projector is ceiling mounted upside down at the height of the top of the screen, then again the default zero user lens shift should put the image properly on the screen. Of course is is great to be able to make small vertical and horizontal shifts to fine tune the final image geometry.
