Vertical & Horizontal Position - Christie Roadie HD+35K User Manual

IMPORTANT !
2.3.2 Vertical & Horizontal Position
Refer to the offsets shown in this section to help determine 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
Describes the elevation of the projector in relation to the screen. For many typical rental/staging installations,
the projector is mounted above screen center. An ideal vertical position helps to ensure that images are
accurately rectangular in shape rather than distorted into a keystoned shape with non-parallel sides, that both
image focus, and brightness remains optimized.
NOTE: Proper vertical position is recommended, although vertically keystoned images (i.e., those with sloping
sides) can be corrected in software. Refer to
The image can be offset vertically (shifted above or below lens center) by using the built-in keypad or the
standard IR remote. Starting with no offset, the 2048 x 1080 image from this projector can be moved by a
distance of up to ±100% of the image height (depending on the lens), resulting in the entire image being
displayed above or below lens center. Refer to

For proper placement in any installation, use the lens and screen size to calculate the precise
throw distance using the tables provided in the Dealer Section of the Christie Website, PN 020-
100395-xx. In addition, please keep in mind that due to lens manufacturing tolerances for lens
focal length, actual throw distance can vary ±5% or more between lenses described as having the
same throw ratio.
