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 2-3x 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. G-301 doesn’t have VGA output. Using HDMI to VGA conversion box to connect projector through VGA port
is not recommended because projector may change the geometry alignment due to “Auto Setting” during
system booth up stage, unless “Auto Setting” function in projector can be turned off.
5. It is possible for the system to hung up during image adjustment. In this case, system will restart within one
minute. User can also turn OFF/ON the system to restart again. This kind of situation will not happen once
the complete system setup is finished. It will not affect the stability of the whole system.
6. If 3D setting in Blue Ray player 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. While executing 2D to 3D
conversion function, please disable 24/30Hz in Blue Ray.
7. Usually front projection 3D screens will be silver (aluminum) surfaced in polarized 3D system unless optical
spectrum filter system like Dolby 3D has been used. Optical spectrum filter system can use normal 2D
screen and minimized the ghost effect (crosstalk) but the filter and glasses will be in higher prices.
8. 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.
9. Please note that head tilting and different viewing angles will affect crosstalk in linear polarization system.
10. It is necessary to recheck the overlap condition of the projectors if there is any output mode change. If
necessary, please use [Profile] to store different settings.
11. In Side by Side or Top-Bottom 3D input mode, user may not see full OSD Menu on the screen. To set
correct video source before implement 3D mode.
12. 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.
