46 Projection 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%.
VSUP: Vertical lens shift range (up) [%]
VSDN: Vertical lens shift range (down) [%]
HSR: Horizontal lens shift range (right) [%]
HSL: Horizontal lens shift range (left) [%]
