Notes:
1. Vertical shift limits are percentages of the screen height. Horizontal shift limits are percentages of
the screen width.
2. Vertical lens shift figures are for ceiling mount configurations. For installations where the
projector is upright, reverse the up/down vertical lens shift percentages.
In rear screen applications where space behind the projector is limited, one or mirrors may
be used to fold the optical path, as shown in Figure 3-5. The position of the projector and
mirror(s) must be accurately set.
