How to Setting Polarization lens in front of projectors: 

1, each pieces polarization lens have A size and B size, you need to put the right side in front of projectors. 

reply:    you takes a circular polarized 3d glasses,  put it in front of  A size polarization lens 

   if you can see the polarization lens  as purple color through the circular polarized 3d glasses ,    then you will put that B side in front of projectors.    ( if you put circular polarized 3d glasses in front of A side and can not see purple color through the circular polarized 3d glasses   then you will  put  A side of CP lens  in front of projects)  

2,  the distance from  CP lens to projector is have no limited, and usually is 10cm~20 cm distance , but you should make the projection of the first projector and the  projection of the second one projector is overlap  on the 3D silver screen.
