Table 3-3 lists the available D-113d lens options and their throw ratios.
Vertical and Horizontal
Position
Proper placement of the projector relative to the screen will yield a rectangular,
perfectly-centered image that completely fills the screen.
Ideally, the projector should be positioned perpendicular to the screen and in such a way
that the lens center is aligned with the bottom edge of the screen area, and centered
horizontally. See Figure 3-2.
