	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.
Adjusting the Projection ➤
	If the screen is significantly higher or lower than the projector, you can also tilt the projector
Angle	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.
