Passive Stereo 3D Configuration; 3D System Timing; 3D Input Video Configurations - Christie Griffyn 4K32-RGB Installation And Setup Manual

Passive stereo 3D configuration

Use the following diagram to understand a typical hardware configuration for passive stereo 3D
systems.
• A—Server/PC with stereo 3D-capable video sources
• B—L/R sync signal (3D-direct input only)
• C—3D direct or 3D dual-input connections
• D—3D active filter cell
• E—Polarization maintaining screen
• F—Passive polarizing glasses

3D system timing

The projected video must be optimized for the glasses' shutter speed or polarization filter performance
to prevent obvious "ghosting" of the video content (known as cross-talk in stereo 3D applications) or
other more subtle color artifacts.
Visual performance can be optimized by adjusting the Dark Interval and the 3D Sync Delay settings.
Consult the documentation for your glasses or polarization filter and keep their specifications in mind
when configuring the projector for 3D operation.

3D input video configurations

The stereo 3D input video stream may be supplied from the video server to the projector in two
configurations: direct-input 3D or dual-input 3D.
Configuration Description
Direct-input 3D In this configuration a single video stream is provided by the video server, with the left eye
and right eye frames supplied as alternate frames within the video stream. A 3D input
sync may be used to identify the left eye frames.
The direct-input 3D video stream may be supplied by a One-Port input video configuration
(such as one cable supplying the entire frame).
