Projection Distance
Projection Distance
The projection distance is the distance between the front of the lens and the surface of the
projected image. The following describes the projection distance and height from the center of
the lens to edge of screen by each projected screen size. 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 the center of the lens to projected image surface).
Never mount the projector on the ceiling or move it by yourself. Be sure to consult with
qualified Sony personnel (charged).
