How to align stacked projectors?
1. Align the reference projector on the screen. See "Aligning the projected image on the screen", page 39.
2. Project an internal hatch pattern with the reference projector . See "Internal patterns", page 205.
Note: The pattern must be sharp and must have a perfect rectangle outline.
If this is not the case, readjust the reference projector before aligning the other stacked projector(s) with the reference
hatch pattern.
3. Project the same internal hatch pattern with the stacked projector . See "Internal patterns", page 205.
Tip: Use a different colored hatch pattern for the stacked projector . This makes it easier to see the difference between both
projected hatch patterns.
4. Adjust the rotation of the stacked projector with respect to the reference projector .
Adjust until the outline of the hatch pattern is most symmetric with the reference hatch pattern.

6. Adjust the skew of the stacked projector with respect to the reference projector .

7. Shift the hatch pattern horizontally and vertically until the outline of the hatch pattern is most symmetrically placed with respect
to the reference hatch pattern.
Note: The “Shift” function is motorized, which means that you have to access the projector software, via the local keypad or
remote control unit, to operate the “Shift” function. See "Lens adjustment, shift", page 176.
