Vertical Lens Shift: The PD8130/PD8150 provides up to 25% of upward vertical lens shift and up to 60% of downward vertical lens shift. For example, with a 100 x 56 inch (1.78:1) screen, you can shift the image up to 14.00 inches
(0.36 meters) above or 33.60 inches (0.85 meters) below the screen center.
Horizontal Lens Shift (PD8150 Only): The PD8150 provides up to 7.5% of horizontal lens shift left or right. 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.
