Runco CL-610 manual Vertical and Horizontal, Position, Folded Optics

Installation

Proper placement of the projector relative to the screen will yield a rectangular,	Vertical and Horizontal
perfectly-centered image that completely fills the screen.	Position
Ideally, the projector should be positioned perpendicular to the screen and in such a way
that the lens center is aligned with either the top or bottom edge of the screen area, and
centered horizontally.
The top of the projected image is even with the lens center when the projector is inverted
(ceiling-mounted). Likewise, the bottom of the projected image is aligned with the lens
center when the projector is upright (as in a floor installation). See Figure 3-2.
