G812 Dual Channel Edge Blending processor
Quick Overview
G812 is a dual channel professional curved screen edge blending processor designed for sophisticated edge blending as well as image warping, stacking, projection mapping…etc.
4 inputs (2x HDMI, 1x DP, 1x VGA) and 2x HDMI outputs are designed in G812. Input supports up to 7680*1200 @30Hz, 4096*2160 @60Hz with 4:4:4 full color sampling. Output supports up to 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 G812. User can perform sophisticated geometry alignment and curved screen edge blending through remote controller, WebGui, USB or Ethernet. Maximum geometry control point is 17x9 grids with 120x68 pixel position fine-tune. Linearity Grid Line Adjustment and “W” type Corner Wall image adjustment for mapping image at 90 degrees or square corner pillar 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 G812. 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 G812 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.
G812 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 G812, 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 G812. User can use either AC power 100V-240V power supply or DC 12V 2A 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.
