1 Introduction
G-700 is a curved screen edge blending processor with the ability to provide multiple processing channels
to control from 1 to 4 projectors based on user’s requirements. G-701 can provide single processing channel 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.
Two G-704 can control up to 8 projectors.
Each processing channel 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 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 each processing channel. In one
G-704, user can display up to 8 different input contents on the screen. If user requires PIP or POP image across
entire screen, user can use the first channel as PIP/POP processor and connect the output to other processing
channel input port to get PIP/POP image across entire screen. If user uses two channels for PIP/POP
processing, then user can get 3-4 different contents across complete edge blending 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. By remote controller,
user can adjust corner position up to H=+_600 pixels and V=+_400 pixels in full HD output resolution. If PC tool
is used, geometry alignment range will be double. User can also apply serial connection among processing
channels to increase geometry adjustment range for some special 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 3840x2160.
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.
