Tilting The Projector - Christie Mirage S+/HD/WU User Manual

The Horizontal position of the image can be offset (i.e., shifted left or
right of lens center) by using the motorized offset function. Starting
with no offset, the image from this projector can be moved left or right
by a maximum distance of 350 pixels for SXGA+ resolution and 403
pixels for HD and WUXGA resolution, resulting in approximately
75% of the image displayed to 1 side of lens center. See
Figure 2-24.
NOTES: 1) If the image becomes keystoned or exhibits uneven
brightness, the projector may simply be too high or low in
relation to the screen. 2) Recommended offset ranges can be
exceeded, however this may affect image quality. 3)
Simultaneous horizontal and vertical offset limits the
adjustment range of each. 4) Offset can vary by ±7% and may
be affected by the degree of zoom currently in use.

section, Lenses for more details.

2.3.3 Tilting the Projector

The projector can be rotated and mounted at any vertical angle (i.e., you can tilt the face of the projector up or
down as much as desired for your installation). Side-to-side tilt, however, must not exceed 15°
Keeping the projector fairly level in this manner ensures that the lamp axis is level, and is required for safe and
reliable lamp operation. Always vent exhaust air away from the lens.
