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.
