• The purpose for image stacking is to increase the total brightness of the projection system. For two 5000 Lumens projectors, the brightness will become almost 10,000 Lumens. The total system cost will be much less than one 10,000 Lumens projector. G-700 is an ideal processor for this purpose. User can stack from 2 up to 4 projectors by one processor. PIP/POP, image rotation and video wall function are embedded in G-700. It allows user has more flexibility to use this processor.
