Projection Distance and Lens Shift Range
The following describes the projection distance and height from lens center to bottom of screen 
by each projected screen size.
The projection distance is the distance between the front of the lens and the surface of the 
projected image.
Height H is the height from the bottom of the projected image (top for ceiling mount) to A 
(determined by drawing a perpendicular line from lens center to projected image...

46Projection Distance and Lens Shift Range
The lens shift range represents the distance in percent (%) by which the lens can be shifted from 
the initial position of the projected image, with full width or full height of the projected image 
regarded as 100%.
