Introduction
M800 is curved screen edge blending processor with the ability to provide multiple processing modules
to control from 1 to 4 projectors based on user’s requirements. M801 is designed with one processing module
to control one projector, M802 for 2 projectors, M803 for 3 projectors and M804 for 4 projectors. It was
designed for sophisticated edge blending as well as image warping, stacking and projection mapping…etc.
One M804 can execute 4 projector edge blending without any additional equipment or splitter. Two M804 can
control up to 8 projectors. More M800 can be cascaded for large scale display.
4 input ports (2x HDMI, 1x DP, 1x VGA) and 1x HDMI outputs are designed in each processing
module. Digital input supports up to 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. 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, Web Gui 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 is a new
function in geometry alignment. Separate R, G, B gamma correction for edge blending region color fine-tune,
individual global color correction for each output, fine pixel color uniformity 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
in M800. It provides more flexible system configuration ability.
HDMI loop out supports daisy chain connection up to 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. Complete curved edge blending can be achieved through remote
controller and Ethernet without PC software, video distributor and splitter.
PIP (picture in picture) and POP (side by side) are standard functions in M800. PIP image size is from
320*180 up to 1920*1200. In one M804, user can display up to 8 different input contents on the screen.
M800 is an ideal solution for simulation. It can connect with inputs from multiple PCs 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 projectors blended) and all-in-
one (three projectors blended). User can also execute edge blending with projector 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. It provides easy configuration, low entry barrier, cost effective, reliable and flexible solution.

1600x1200, 1920x1080 (24/30/50/60Hz), 2048x1080/60 & 1920*1200/60。All output
default resolution is 60Hz, RGB 4:4:4 and progressive.
✓If the output refresh rate is not the same as input refresh rate. The frame lock function will
be disabled and it may cause not synchronization issue among output channels. If the
input is 4k/30 with FHD/60 output, it will have no synchronization problem. If the input is
50Hz, please select 1080p 50 Hz output to avoid frame repeat issue.
✓User can set EDID to let input source provide desired resolution. However, input resolution
is controlled by signal source and may not output desired resolution. In this case, manual
setting in signal source output resolution may be required.
✓M800 can support non-VESA standard input timing once signal source can provide, such
as 4096x2160, 3200x2400…
✓When press [OTH] key to select output resolution in remote controller, the monitor will
show the timing and take few seconds to finish the selection.
✓User can click [Info] key to get system information and input / output signal resolution.

2.11. OSD Lock and unlock
➢If multiple units of GeoBox is installed together or the IR receiver is put together, in order to
avoid interference among multiple GeoBox during the installation, user can set different ID
number for each GeoBox through [Options] Menu. Press number keys in Remote Controller to
determine which GeoBox will be controlled.
- 851: control GeoBox ID No. 1
- 853: control GeoBox ID No. 3
- 850: to unlock all units and user can control all GeoBox.
- User will see flashing LED on front panel after press 85x number keys. It means the OSD
menu in GeoBox with flash LED is locked and will not be controlled by remote controller.
➢OSD Lock / Unlock: When continuously press [Menu] key in IR Remote Control for 5 seconds,
the OSD function will be locked to prevent from setting change by negligence. To press [MENU]
key for 5 seconds again, it will unlock OSD and user can manipulate the OSD again.
2.12. System synchronization
When the system uses multiple projectors, the image should be synchronized together. GeoBox
uses [Frame Sync] to synchronize all outputs based on the input signal vertical sync. When [Frame
Sync] is applied, it is possible to lose sync during system setup and cause the projector to re-search
the signal source. In order to provide smoother setup, GeoBox provides OSD for user to select
different synchronization methods for easy setup.
➢[Normal] (Frame Locked): when user uses multiple units of GeoBox, we propose to set at
[Normal] to let all output synchronized together. The sync time will be longest. When user reset
system or adjust video wall settings, user may see projector re-searching the input source.
➢[Fast] (Phase lock): time to sync the input source will be fast than [Normal]. However, due to
projector still needs to re-search input signal, the total signal change time including projector re-
searching will be very similar.
➢[Disable] (Free-Run mode): when GeoBox changes input source or timing, the output will be
still running without losing any signal. The projector will not search the input source again.
