Vertical And Horizontal Position; Vertical Position; Vertical Tilt - Christie CP2000-XB Setup Manual

Vertical and Horizontal Position

Refer to the offsets shown here for help in determining how high or low to install the projector in relation to the
center of the screen, and/or how far off to one side.

Vertical Position

escribes the elevation of the projector in relation to the screen. For many typical large venue rental/staging
D
installations and theatres, the projector will be above screen center. An ideal vertical position helps ensure that
1) images will be accurately rectangular in shape rather than distorted into a keystoned shape with non-parallel
sides, and 2) focus and brightness will remain optimized.
Vertical position of the image can be offset—that is, placed higher or lower in relation to lens center—using
the Up/Down Offset buttons from the Main: Lens menu. Starting with no offset, the 2048 x 1080 image from
this projector can be moved by a maximum distance of 540 pixels, resulting in all of the image displayed above
or below lens center (Figure 2-13).

Vertical Tilt

Describes the angle of the projector in relation to the screen. Ideally, the projector should be inclined to match
the screen, so that the face of the lens and the surface of the screen are parallel to each other. To adjust to the
height and level of the projector, extend or retract the feet by rotating them. Refer to Figure 2-17.
NOTES: 1) Assumes full 2048 x 1080 display. 2) Recommended offset range can sometimes be exceeded,
however this may affect image quality. 3) Due to manufacturing tolerances, an offset range can vary ±5% or
more between lenses described as having the same throw ratio, between projectors, and with any lens/
projector combination. 4) Simultaneous horizontal and vertical offset can limit the adjustment range of each,
as can long throw distances.
