11.2 System installation and setup
a. GeoBox should not put at side of the projector where the ventilation hot air comes out.
b. Two projectors can be put side by side or top/bottom. Closer position will reduce geometry
adjustment range and reduce the loss of the image resolution and brightness. Please make sure
hot ventilation air will not affect the other projectors. Isolated board between two projectors can be
added if necessary.
c. Set higher output resolutions (such as FHD) from 3D signal source and connect to any input of
GeoBox. GeoBox will decode and distribute the signals for two projectors.
d. Each GeoBox is connected to one projector for right/left eye display.
e. Install polarized filter at some distance from projector lens to avoid thermal damage (at least 5-10
cm).
f.
Setup the polarized filter and glasses so that right/left eye can only see the scene for one eye.
g. Use geometry alignment function to align the images from two projectors completely matching
together. Please place the polarized filter in front of the projector before [4 Corner] adjustment
because polarized filter will affect the direction of light beam from projectors. Some deviation is
allowed for 3D display but will affect the performance in 2D display. A good alignment will give double
brightness for the projection in 2D display. For a good double brightness application, two projectors
should be placed as close as possible and the screen must be flat or smooth curve.
