G802 is dual channel processor with the ability for warp, geometry alignment, image stacking, edge blending and edge mask...etc. It can control up to two projectors and work with other GeoBox edge blender for large scale edge blending system. Four inputs, two outputs and one loop out port are designed in G802. User can display one big edge blended image or two independent displays in one system. The signal source for two independent displays shall come from HDMI+DP, HDMI+VGA or DP+VGA. No PIP/PBP function is built in. User can use low cost projectors without lens shift, warp or edge blending. Except for signal source, projector and HDMI cable, no additional device, PC or propriate software tool is required. It is a low entry barrier, reliable and cost effective edge blending solution. 

G804 is designed with two G802 processing modules for flat and curved screen edge blending with the ability for warp, geometry alignment, image stacking, edge blending and edge mask...etc. It can serve as one four channel edge blender or two dual channel edge blenders. Eight inputs, four outputs and two loop out ports are designed in G804. User can display one big edge blended image or two independent displays in one system. Each output channel can also display independent image.
