9. 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.
10. PC 3840x1080P side by side 3D signal can be decoded into two full HD signals for passive 3D display.
Active 3D application
G-303 is also a powerful active 3D controller. It can support Blue Ray 1080p 24Hz frame packed and PC Nvidia
1080p 120Hz 3D signal and convert it to 720p/XGA 120Hz output signal for DLP-Link 3D Ready or Nvidia 3D
Vision active 3D display. Users can also stack two active 3D projector together (by keystone or lens shift) and
connect the signals from two outputs of G-303 to provide double brightness active 3D display. If bigger screen
is required for active 3D edge blending applications, G-502 (for flat screen) or G-104 (for curved edge blending)
can be chosen for this purpose. For Nvidia 3D Vision active 3D display, it may be necessary to do optimization
in the factory according to different projector model to get the best video quality.
Nvidia 3D Vision 1080p @120Hz active 3D displayed in passive 3D system
Due to the limitation and uncomfortable in active (shutter) 3D system, more and more customers are requesting
to have low cost devices to support active 3D signal displayed in passive 3D system to get stable and
comfortable image. The following GeoBox models can support frame sequential active 3D formats: G-104, G-303,
G-501 & G-502.
System connection
1. HDMI 1.4a can only support up to 720P @120Hz active 3D signal.
2. If user wants to display 1080p @120Hz 3D signal, then DualLink DVI or
DisplayPort connection is required.
3. Many PC has multiple outputs. Please connect with the right port that
output from display card to get better performance. Most mother board
embedded card can only support up to 720p/XGA 120Hz.
GeoBox setting
1. Select the right input source—DualLink DVI, DisplayPort or HDMI.
2. Set output resolution as the same native resolution of the projector.
3. Set 3D [Input Format] at [Automatic] for signal embedded with 3D INFO. If user sees top-bottom or side by
side image from the PC, then please select the right [Input Forma] based on the output from PC format.
4. Select correct [Output Format] for R/L output channel. Don’t enable 120Hz output.
5. Make sure correct passive 3D setting, filter, glasses and screen are ready for passive 3D display.
