Figure 3-3. Projector Placement
You can use the lens shift controls on the projector to center the image on the screen.
Lens shift is generally expressed as a percentage of the screen height or width, as shown
in Figure 3-4.
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.
Figure 3-4. Vertical Lens Shift (Example Only)
The LS-1 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.
