Table 3-3 gives the lens shift limits for the Vision 10 and Vision 12, as percentages and
absolute measurements with a 96 x 54 inch (1.78:1) screen.
Adjusting the Projection
Angle
If the screen is significantly higher or lower than the projector, you can also tilt the projector
at a slight angle. In a ceiling installation, you do this by adjusting the ceiling mount. For a
floor installation, turn the four adjustable feet on the bottom of the projector to adjust the
projector height and/or projection angle.
If you do this, you may need to shift the image or apply keystone correction using the
on-screen display (OSD) controls, to compensate. For detailed instructions, refer to
Using the
On-Screen Menus on page 32.

Notes:
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 apply to ceiling mount configurations. For floor installations (where the
projector is upright), reverse the up/down vertical offset percentages.
