Try aligning the two grid patterns
Adjust 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 Step 7 to lock all stacking mounts.

If alignment needs improvement, proceed with the next step.

Align the centerlines of the grid

Turn the two rear stacking mount wheels
to move the top projector as necessary for
well-aligned centerlines. Use a
screwdriver in the holes around the rim
of each adjusting wheel for better
leverage and control.

HOW TO MOVE THE IMAGE:

independently, each stacking mount acts
as a pivot point for the opposite edge of
the display (Figure 2.15). For example,
turn the right mount to tilt the left portion
of the image up or down, and 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 "X":
are slightly tilted in relation to one another. Turn one mount to raise one side, and/or
turn the other mount to lower other side. See Figure 2.15.

IF THE CENTER LINES ARE PARALLEL BUT MISALIGNED:

 If centerlines are out by the same amount from top
and bottom – use offsets (on top projector) to bring
the centerlines into alignment.
 If centerlines are parallel but
others are not, turn the front
stacking mount wheel to bring the
centerlines into alignment.
