How to align stacked projectors

1. Make sure that the internal hatch pattern projected by the reference projector is sharp and has 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.

   

   Note: The reference projector in a stacked configuration is the lowest projector in case of table mount and the uppermost projector in case of ceiling mount.

2. Project with the stacked projector the same internal hatch pattern as the reference projector.

   

   Tip: Use a white colored hatch pattern for the reference projector and e.g. green colored for the stacked projector. This makes it easier to see the difference between both hatch patterns projected.

3. If necessary, adjust the rotation of the stacked projector with respect to the reference projector by turning in or out the height adjustment ring of the interlocking adaptors at the rear of the stacked projector. Adjust until the outline of the hatch pattern is most symmetric with the reference hatch pattern.

   

4. If necessary, adjust the inclination of the stacked projector with respect to the reference projector by turning the height adjustment ring of the interlocking adaptor at the front of the stacked projector in or out. Adjust until the outline of the hatch pattern is most symmetric with the reference hatch pattern.

   

5. If necessary, adjust the skew of the stacked projector with respect to the reference projector by turning the Hand screw in or out. The hand screw is located at smallest side of the carrying handle (front or back). Adjust until the outline of the hatch pattern is most symmetric with the reference hatch pattern.

   

6. 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: Note that 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.

7. Zoom the hatch pattern in or out until the outline of the hatch pattern matches exactly the outline of the reference hatch pattern.

   

   Note: Note that the “Zoom” function is motorized, which means that you have to access the projector software, via the local keypad or remote control unit, to operate the “Zoom” function.
8. If necessary, repeat from step 2 until the hatch pattern of the stacked projector is perfectly aligned with the hatch pattern of the reference projector.
