IR Emitter/3D Passive Filter System: In response to an incoming sync signal, the emitter emits L/R infrared
signals to a receiver in active 3D shutter glasses, causing the L/R shutters to alternately open and close for
active stereo 3D applications. Likewise, a 3D passive filter system placed in front of the lens responds to an
incoming sync signal and alternately polarizes the L/R frames viewed with passive glasses for active stereo 3D
applications. Connecting one of the 3D Stereo Sync Cable outputs to an emitter/3D passive filter system
allows you to synchronize your stereo 3D display with the glasses.
Glasses (Active/Passive): Active glasses differ in speed and performance. Consult the documentation for your
glasses and keep their specifications in mind when configuring your source signal. The input signal must be
optimized for the available shutter speed to prevent obvious "ghosting" of image content (known as cross-talk
in stereo 3D applications) and other more subtle color artifacts. Such problems indicate that the eyes are
detecting portions of the opposing frame due to an "out-of-sync" system, and can occur in either active or
passive stereo 3D configurations. Adjust the Dark Interval setting to reduce ghosting.
In the 3D Settings menu, the correct "3D Stereo Sync Delay" setting should help to synchronize glasses with
the displayed images. NOTE: In a passive system, where glasses do not have shutters and instead depend on
the speed and accuracy of the 3D passive filter system, the signal must be synchronized to the projector via the
3D Stereo Sync Cable.
4.2 3D SETTINGS
Use the options in the 3D Settings menu to make the timing adjustments necessary for realistic simulation and
3D images. See
3D State: Informs you what state the projector is in: Off, Missing Secondary Signal, Not Frame Locked,
Secondary Frequency Mismatch, High Bandwidth Not Supported, Stereo Sync Not Detected, Stereo Sync
Invalid, and Invalid Frequency.
