G804 4-CH edge blending processor

Quick Overview

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. No PIP/POP 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 processing modules of G802. It can serve as one quad channel edge blender or two independent dual channel edge blender. It is designed for professional flat and curved screen edge blending as well as image warping and stacking.

8 inputs (4x HDMI, 2x DP, 2x VGA) and 4x HDMI outputs are designed in G804. Input supports up to 7680*1200 @30Hz, 4096*2160 @60Hz with 4:4:4 full color sampling. Output supports up to WUXGA or 2048*1080 @60Hz. It is integrated with 10-bit high end processor, motion adaptive de-interlace, low angle smooth algorithm, 3:2/2:2 pull-down and supports non-VESA standard input timing for connecting with various input sources.

Advanced warp technology is embedded in G804. User can perform sophisticated geometry alignment and curved screen edge blending through remote controller, WebGui, USB or Ethernet. Maximum geometry control point is 17x17 grids. Linearity Grid Line Adjustment and Corner Wall image adjustment for mapping image at 90 degrees corner is a new function in geometry alignment. Separate RGB gamma correction for edge blending color fine-tune, individual color correction for each output, fine pixel color uniformity and 9 regions non-edge blending area black level uplift are also embedded in G804. Users can see real time geometry and colour adjustment to get optimized result.

HDMI 2.0 loop out supports daisy chain connection up to 7680*1200 @30Hz and allows large display with multiple units cascaded. Video wall function in G804 is to crop and allocate source image for each projector and set overlap pixels for edge blending. Complete curved screen edge blending can be achieved through remote controller or Ethernet without PC software, video distributor and splitter.

G804 is designed to support programmable EDID and non-VESA standard input. User can create any EDID timing in the range between 1024x768 and 3840x2400 in order to optimize video performance.

Using G800, 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.

Dual power supply system is embedded in G804. User can use either AC power 100V-240V power supply or DC 12V 3A power supply with external DC 12V power adapter. When apply AC power supply, user will have one DC 12V 1A output for signal extender. Standard delivery will be packed with AC power cord only.
