An Excel Spread Sheet can be provided for the calculation of the Video Wall Overlap setting value.

For dual projector edge blending, user can increase [Overlap] value in each channel at the same
time. Then user will see the overlapped images to come closer till two image 100% match together.
c
、
For dual projector edge blending, user can use below equation to calculate overlap pixel.
Assumption: Input signal:1080p, G-700 output to projector: XGA, Overlap 224 pixels (7 grids)
Overlap value=1920/(1024*2-224)x(224/2)=118 pixels.
10 Passive 3D Display
10.1 System Configuration
GeoBox will decode 3D format from all kinds of 3D video sources, including Blue Ray DVD, STB, Media
player, Game console and PC… 3D signal will be decoded by GeoBox into signals for Right/Left eyes.
The signal needs to be displayed through two projectors. Each projector will display signal only for right
eye or left eye. User needs to set a polarized filter in front of the projector and also wears polarized
glasses. The glasses need to match the polarized filter in front of the projectors so that the right eye can
only see the scene for right eye and the left eye can only see the scene for left eye. Silver 3D screen is
also required to preserve the polarization of the light for 3D display. It is possible to use optic spectrum
method from Dolby, Infitec or Omega Optical to allow 3D displayed on normal 2D screen.
10.2 System installation and setup
After video wall Overlap adjustment and
apply Edge Blending: No more double
image in overlap region and smooth the
uniformity of the color and brightness.
