M804 quad channel edge blending processor

M804 has 4 processing modules for control up to 4 projectors. It can work with other GeoBox edge blender to control various number of projectors for large scale display.

Each processing module has 4 input ports (2x HDMI, 1x DP, 1x VGA), one HDMI loop out port for daisy chain connection and 1x HDMI outputs. Digital input supports up to 8k/2k (2k/8k) @30Hz, 7680*1200 @60Hz and 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. Programmable EDID can optimize input timing to get the best video result.

Advanced warp technology is embedded in M800. User can use IR controller, USB, WebGui and Ethernet to perform edge blending and sophisticated geometry alignment up to 17x17 control points. Linearity Grid Line Adjustment and Corner Wall image adjustment for mapping image at 90 degrees corner wall is a new function in geometry alignment. Separate R, G, B gamma correction for edge blending region color fine-tune, individual color correction for each output and 9 regions non-edge blending area black level uplift are also standard functions in M800. Users can see real time geometry and color adjustment to get optimized result.

Image 90/180/270 degrees rotation and flip with 4k/60 input from various input sources are embedded. It provides more flexible system configuration.

HDMI loop out supports daisy chain connection up to 8k/2k @30Hz / 4096x2160 @60Hz and allows large display with multiple M800 cascaded. Video wall function in M800 is to crop and allocate source image for each projector and set overlap pixels for edge blending. User can also adjust image aspect ratio through Video Wall Overlap function. Complete curved screen edge blending can be achieved through remote controller and Ethernet without additional devices except for signal source and projectors.

PIP (picture in picture) and PBP (side by side) are standard functions in each processing module. PIP image size is from 320*180 up to 1920*1200. If user wants to have PIP/PBP/MultiViewer across entire screen, please add one G901 to get the highest flexibility.

M804 is an ideal solution for simulation. It can support up to 7680x1200/60Hz input resolution or connect with inputs from multiple PCs to combine them into one big seamless image. Edge mask can mask out unnecessary image. It also provides flexible displays in edge blending system. For a 4x projector edge blending system, user can configure as 1+1+1+1 independent display, all-in-one (4 projectors blended), 2+2 or 3+1 (3 projectors blended + one independent display). User can also execute edge blending with projectors at portrait position without rotating source image to increase image height. It is a good fit with laser projector without the limitation in installation angle.

Using M804, users can replace high end projector with low-cost projector without lens shift, warp and edge blending and get the same result. It provides easy configuration, low entry barrier, cost effective, reliable and flexible solution.
