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.
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.
