Placing the upper projector
Follow the same procedure as above for the lower projector taking in account that this
projector is placed on a special adjustment plate. When placing the unit make sure the
plate is horizontal also looking at the small bubble level mounted in the middle.
Fine aligning the images
The C3X LUMIS model composing the system has 50% UP lens shift. An optimal
installation is obtained without using electronic keystone, so when the image is projected
perpendicular to the screen.
This means that the system should be placed in order to have the upper projector’s
projection lens at a height equal or lower than that of the screen center. On the other
hand, the lower projector’s projection lens minimum height has to be on line with the
bottom edge of the screen.
The best result is obtained when the upper projector has no lens shift and the lower one
has slight lens shift up.
Once found the right system height follow these steps:
1. Turn on the projectors
2. Adjust the image by moving the motorized zoom and focus commands on both
projectors to fit the screen dimensions. To do it easy, use the zoom and focus
patterns. Find very close image sizes by both units.
3. Act on the lens shift of both unit using the provided allen spanner in order to find
the same image center height. Help yourself by a cross test pattern like the zoom
test pattern
4. If you see that the upper projector image has a lot of horizontal keystone you can
unscrew the 4 adjustment plate knobs fixing it to the structure and rotate it till the
image has no more keystone (see below image).
