       Quad channel 4k projector edge blending processor

Product Description


        G-700 is a curved screen 4k projector edge blending processor with the ability to provide multiple processing modules to control from 1 to 4 projectors based on user’s requirements. G-106Ex can provide single processing module for one projector, G-702 for 2 projectors, G-703 for 3 projectors and G-704 for 4 projectors. It was designed for sophisticated edge blending as well as image warping, stacking, projection mapping, irregular video wall and passive 3D…etc. One G-704 can execute 4 projector edge blending without any additional equipment or splitter. 

        Each processing module has 3 input ports (1x HDMI, 1x DP, 1x DVI-I) to support 5 input formats (HDMI, DP, VGA, DVI-D, YPbPr) and one HDMI output port. One 4K/2K HDMI loop out port is for raw signal daisy chain connection. Input ports support up to 3840x1080 @60Hz and 4k UHD @30Hz resolution with 4:4:4 full color sampling. It is integrated with 10-bit high end processor, motion adaptive de-interlace and 3:2/2:2 pull-down.

        PIP (picture in picture) and POP (side by side) are standard functions in G-700. In one G-704, user can display up to 8 different input contents on the screen..

        Advanced warp technology is embedded in G-700. User can use front panel keypad, IR controller or PC to perform edge blending and sophisticated geometry alignment up to 17x17 grids through user friendly operation interface. Geometry adjustment range is big enough for most of the applications. 

        It can perform color and white balance adjustment in individual projector. Edge blending region gamma correction and non-edge blending area black level uplift are also standard function in G-700.

        HDMI loop out supports daisy chain connection up to 3840x1080 @60Hz or 4k/2k @30Hz and allows large display with multiple G-700 cascaded without video distributor. Video wall function in G-700 is to crop and allocate source image for each projector. Complete curved edge blending can be achieved without PC, video distributor and splitter.

        G-700 is an ideal solution for simulation. It can connect with inputs from multiple PC and combine them into one seamless image. It also provides flexible displays in edge blending system. For a 3x projector edge blending system, user can configure as 1+1+1 independent display, 1+2 (two edge blends) and all-in-one (three edge blends). User can also execute edge blending with projector at portrait position to increase image height. It is a good fit with laser projector without the limitation in installation angle.

        In order to optimize video performance, G-700 is designed to support non-VESA standard input timing and allow user to create any EDID timing in the range between 1024x768 and 3840x2400.

        With G-700, users can replace high end projector with low cost projector without lens shift, warp and edge blending. It provides easy configuration, low entry barrier, cost effective, reliable and flexible solution.
