Vertical Lens Shift
You can use the lens shift (LENS) controls on the projector remote to center the image on the
screen. Vertical lens shift is generally expressed as a percentage of the screen height, as
shown in Figure 3-3.
Figure 3-3. Vertical Lens Shift (Example Only)
The Vision 65/75 provides up to 35% of vertical lens shift above and up to 50% of
vertical lens shift below the screen center.
For example, with a 100 x 56-inch (16:9) screen,
you can shift the image up to 19.60 inches (0.50 meters) above or 2
8
.00 inches (0.71 meters)
below the screen center.
➤
1. With no vertical lens shift, the lens center and screen center are aligned
with each other.
2.
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.
