M804 quad channel edge blender

Quick Overview

M804 is designed with 4 processing modules. Each module can work separately or work together to serve as one 4 channel processor. It can execute edge blending on flat screen, curved screen, 360 degree screen and 90 degree corner wall.  User can combine the images on the ceiling, wall and floor to create immersive display through GeoBox edge blending technology. One M804 can build one big image across all projectors as well as partial edge blended or discrete content in each projector.  All the settings can be saved inside M804 and recall through remote controller, RS232, USB or Ethernet at any time. It is world unique technology to setup all kinds of edge blending and immersive system without PC, software or additional device. 

M800 has 4 models to control from one projectors up to four projectors. M801 is integrated with one processing moduel for control one projector. M802 is integrated with two processing moduels for two projectors. M803 is for 3 projectors and M804 is for 4 projectors. Multiple M800 can be configured for various projectors and 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 POP (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/POP/MultiViewer across entire screen, please add one one G901 to get the highest flexibility.

M800 is an ideal solution for simulation. It can connect with inputs from multiple PCs and combine them into one seamless image. Edge mask can mask out unnecessary 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, all-in-one (three projectors blended) and 2+1 (two 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 M800, 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.
