Alignment Procedure - Christie J Series User Manual

2.4.5 Alignment Procedure

Stacked projectors must be correctly aligned to one another so that the resulting display is optimized and as
sharp as possible. If you are also hoisting the stack, hoist the stack into place first and then align. Lock all
stacking hardware into place to maintain your alignment.
IMPORTANT! Ensure the stacking legs are extended at least 1 inch and are slightly loosened.
Before You Begin
• Always align to the fixed projector. In floor-mount or table-mount (i.e., non-hoisted) stacks, you will align to
the bottom projector as shown in drawings below. In hoisted stacks, align to the top projector.
• Leg nuts must be loosened before alignment; otherwise the stacking mounts will not turn and allow
movement of the projector.
Alignment Procedure:
1. Position the fixed projector (first) image as desired and align the other image(s) to it as described below.
2. Display the Grid Test Pattern. To distinguish each image, enable "Red" for 1 display and "Green" for the
other. See 3.6 Image Settings Menu
3. Focus the images for both projectors.
4. Adjust the Zoom and Offset on the top projector to precisely move its test pattern display on to the bottom
test pattern. When properly aligned, all red/green grid lines in the combined image will turn yellow.
• If all lines are well aligned, skip to
• If alignment needs fine adjustment, proceed with the next step.
5. Turn the 2 rear stacking mount wheels to move the top
projector as necessary to achieve well-aligned center lines. Use
a screwdriver in the holes around the rim of each adjusting
wheel for better leverage and control.
How to move the image. Turn independently; each stacking
mount acts as a pivot point for the opposite edge of the display.
For example:
• Turn the right mount to tilt the left portion of the image up or
down
• Turn the left mount to tilt the right portion of the image up or
down
• Turn the mounts together to raise or lower the top image like
an offset adjustment, or turn the front stacker
If the center lines form an
projectors (and images) are slightly tilted in relation to
one another. Turn 1 mount to raise 1 side, and/or turn the
other mount to lower the other side.
If the center lines are parallel, but misaligned:
• If center lines are out by the same amount from top and
bottom, use lens offsets (on top projector) to bring the
center lines into alignment.
