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).
