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.
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
on page 30.
