Figure 3-5. Horizontal Lens Shift (Example Only)
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.
