Offsets; Focus; Auxiliary Lens - Christie CP2000-SB User Manual

Offsets

From the Main: Lens menu, click the up/down/left/right buttons as necessary to adjust the image and make it
square on the screen. For best results, avoid extreme tilts or offsets. Corner vignettes on a white test pattern
indicates extreme offset that should be avoided. If you need more vertical offset range, it is possible that the
projector's mechanical TILT should be changed to help compensate for significant differences in screen and
lens height.

Focus

From the Main: Lens menu, click the focus buttons as necessary for overall focus improvements. For best
results, use a crosshatch test pattern or similar, and focus on the center of the image.
If the focus quality differs from edge-to-edge (whether top, bottom, left or right), the boresight of the lens
mount likely needs correction. Refer to

3.9.2 Auxiliary Lens

NOTES: 1) The auxiliary lens and its motorized mounting mechanism are optional. 2) To install, replace or
use the auxiliary lens, refer to the instructions included with the Motorized Auxiliary Lens Mount kit.
To widen a squeezed image into a scope (2.39:1) theatre display, swing the 1.25x anamorphic or 1.26x wide
converter lens into place in front of the primary zoom lens of the projector. This lens increases magnification
across the width only, regaining the original proportions in the image, and is often used in theatres where side
masking can be moved aside.
