About GeoBox
Vns Inc. designs and manufactures a series of high end video processor “GeoBox”
to expand the application of projector. State-of-the-art technologies are
integrated in the design, including 10-bit processor with advanced video
processing, Perfect Sync 3D synchronization and patented warp technology.
GeoBox is a standalone system for up/down scaling, format conversion, video
wall, 3D demultiplexer, curved surface display, sophisticated image edge
blending, image stacking and quick 4 corner adjustment up to WQXGA input and
WUXGA (& full HD) output. It is a robust and reliable design to meet demanding
industrial standard & requirements.
Flexible, easy, convenient and high performance are the key features of GeoBox. It
takes only very short time for the settings of GeoBox in two projector stacking,
edge blending or high quality passive 3D display. No PC or special tool is required
for the installation and setup.
Convenient features for system integrators:
Ÿ Full functional keypads on front panel .
Ÿ Standalone, no PC or special tool is required, better perfomance, more reliable.
Ÿ Friendly user interface. Real time result.
Ÿ Only few minutes for the setup of dual channel edge blending, image stacking

or passive 3D applications.
Integrated IR extender to extend IR control up to 20 meters for easy installation.
ID number can be assigned to each GeoBox for individual control.
User can easily lock the keypads to prevent setting changes by negligence.
Five profiles can be saved and recalled to provide different display modes.
Use low cost projectors without lens shift or keystone correction.
Can be controlled by smart phone or Ethernet.

2D/3D Multi-Projector Stacking System
Brightness increase by 2x, 3x, 4x... You can yield 10k lumens by using three 3,500 lumens projectors paired with one G-301 at
less than 1/3 cost compared with one 10k projector. Using GeoBox patented precise geometric adjustment, user can stack
more projectors to get higher brightness with fraction of cost increase. Another major advantage is that even some projectors
are broken down during the operation, user still can keep the system running without affect important events. It also supports
image stacking on curved screen.
Stacking processor
(support curved screen stacking)
2x projectors: G-202
No need to add video splitter, with 1x
DVI-I input, 1x DVI-D output and 1x

3x projectors: G-301
No need to add video splitter, with 1x
VGA, 1x DVI-D, 1x HDMI inputs, 2x
HDMI outputs and 1x HDMI loop back
