Notes:
1. With no vertical or horizontal lens shift, the lens center and screen center are aligned with each
other.
2. Vertical shift limits are percentages of the screen height. Horizontal shift limits are percentages of
the screen width.
3. Vertical lens shift figures are for ceiling mount configurations. For floor installations
(where the projector is upright), reverse the up/down vertical lens shift percentages.
