Horizontal Lens Shift:
The projector provides ±30% of horizontal lens shift. For example, with a 100 x 56 inch (1.78:1) screen, you can shift
the image up to 7.50 inches (0.19 meters) left or right of the screen center.

Note
This is a general example of lens shift. Lenses vary in their shift capabilities. No particular lens or
projector is used in this example.

Note
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 percent‐
ages 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.
