Projector mounting height should be determined from the projection geometry, not simply from the ceiling height. Screen position, lens centerline, projector offset, lens shift range, throw ratio and mounting orientation all influence the correct installation height. This guide explains how to plan projector mounting height for ceiling-mounted, short-throw, large-venue and professional AV installations.

This guide explains projector offset and how the projected image is positioned relative to the projector lens centerline. Learn the difference between fixed image offset, lens shift and digital keystone correction, and understand how ceiling height, screen position, throw ratio and projector orientation should be evaluated together during installation.
