How to set up the system
In this chapter, the setup procedure for the projectors is explained, but a setup procedure must also be
performed for the picture source.
In order to obtain a satisfying result for the Blend function, the overlap / Blend zone are
recommended to be at least 10% of the picture width.
The basic principle is that the overlap setup in the source shall correspond with the blend width setup for the
projector. That means that if the overlap zone for the source is set to 500 pixels, the width of the blend zone for
the projector also must be set to 500 pixels.
First step is to align the image from the projectors as accurate as possible in a mechanical way, meaning
without any optical corrections. At the same time, establish an overlap in the pictures between the two
screens.
Then adjust the remaining irregularities by using the shift and warp features in the projectors to obtain the last
fine tuning of the alignment.
Setup the source to a blend which corresponds with the preset overlap on the screen. There are different ways
to do this, depending on the source. Refer to the source unit's manual for this issue.
Adjust the Blend for the projectors as described below.
