GeoBox image stacking video processor with video switcher function can increase the projection brightness easily by 2x, 4x, 6x....User can get 10k lumens by using 3 projectors with 3,500 lumens paired with one G-301 at less than $0.3 per lumen. Using GeoBox patented warp technology, user can stack more projectors to get more brightness with fraction of cost. By using G-501, which is designed with 6 inputs and 10-bits high end video processor, user can get a stacking system with multiple projectors together with high end scaler box, format converter and video switcher function in one box. Another major advantage is that even some projectors are broken down, user still can keep the system running without affect important events.


Image stacking function can be applied on both flat screen and curved screen with large and flexible geometry adjustment range. For output resolution under 1400x1050, the corner position or curve adjustment range can be up to +_512 in horizontal position and +_400 in vertical position.


Quick Switching Mode in GeoBox will eliminate re-sync and input searching in the projector while input timing and signal source change under the same fresh rate and video system (i.e. NTSC/PAL). It will save the time with smooth mode change.
