NOTE:

•The optional lenses for GT6000/GT5000 have different geometrical distortions in wide zoom and tele. Select the best zoom position for stacking where the geometrical distortion is as small as possible.

•The optional lens GT06RLB and GT10RLB do not support stacking.

For double stacking, follow the instructions described below.

z-2. Stacking the Projectors

Place the projectors at the proper height for best screen to projector relationship. Make sure that all projectors have the same display orientation.
