Other Important Tips for 3D display
1. The final brightness to the eyes will be reduced due to 3D polarizer and glasses. Passive 3D brightness to
the eyes will be about 2.5x if compared with the same projector used in active (shutter) 3D system.
2. Incorrect aspect ratio adjustment of signal source may cause abnormal 3D display when the 3D format is
Side by Side or Top-Bottom.
3. Pair the glasses and polarizer is required: If viewer wears 3D glasses and sees the light from lamp through
one polarizer via RH eye with different side, direction and angle, viewer will see below conditions:
i.
If RH eye can see through the polarizer at any side, direction and angle, then this polarizer is not for RH
eye. It should belong to LH eye projector.
ii.
If viewer can’t see through or only see minor light at some angle or direction, then it can be for RH eye
projector. The side faced to the eye should be pointed out to the screen and the polarizer should be
installed at the same angle as viewer sees minimum light through.
4. GeoBox doesn’t have VGA output. Using DVI to VGA conversion box to connect projector through VGA port
is possible. However, the video quality in VGA port is not as good as digital interface. It may also have some
issue in position shift due to projector Auto Adjustment function. User needs to check above issues before
installation. To turn off projector Auto Adjustment function is one possible solution to fix this issue.
5. If 3D setting in Blue Ray is not correct, GeoBox will not be detected and 3D signal can’t be delivered to
GeoBox. Please set Blue Ray at auto 3D or 1080p@24Hz frame packing.
6. Usually front projection 3D screens will be silver (aluminum) surfaced in polarized 3D system unless optical
spectrum filter system from Dolby, Omega Optical or Infitec has been used. Optical spectrum filter system
can use normal 2D screen and minimize the ghost effect (crosstalk) but the filter and glasses will be in
higher price.
7. There are many kinds of 3D polarization system with different polarizing angles or directions. User needs to
check whether the glasses can match exactly with polarizer being used for the projectors.
8. Please note that head tilting and different viewing angles will affect crosstalk in linear polarization system.
9. In Side by Side or Top-Bottom 3D input mode, user may not see full OSD display from the video sources
(such as media player). Please set correct video source before implement 3D mode.
10. Although GeoBox is the most advanced and comfortable 3D control system, 3D screen, polarizer and
glasses are also important factors for a perfect 3D system.
Video Wall
G-201 has pure hardware video wall function. Each G-201 can handle two image channels with overlap at any
individual edge or all edges. It can do image cropping, split and assign the location of each image. The overlap
pixel between two images can also be adjusted pixel by pixel so that the video wall can meet the requirements in
different application environment. The maximum video wall can be up to 15x15 matrix display. If it works with
G-202 edge blending processor, it will provide a complete projector edge blending solution.
The purpose for Video Wall Setting is to determine the display Matrix, split the image, assign each
GeoBox/display device to the right location in the matrix and set overlap region.
