3D Troubleshooting
3-56
For future single-input 3D sources where the server supplies a separate 3D stereo
sync to the projector's GPIO port instead, set Input GPI according to which
input# is used (i.e., according to your GPIO cable wiring).
4.
DEFINE L/R DOMINANCE
depends on the cameras used during filming, and is needed to ensure smooth
motions. An incorrect setting creates motion artifacts.
5. DEFINE SYNC DISPLAY LOCATION:
 Set L/R Display Reference to Not Used.
 Set Display GPI to None.
6.
DEFINE SYNC OUTPUT:
signal output from the projector's GPIO port (to your emitter or polarizer)
matches the L/R order of the incoming frames, or whether it is to be inverted—
i.e., reversed (R/L). Then set the Output GPO according to which of the
projector's GPIO outputs is currently wired to your emitter or polarizer.
7.
CONNECT GPIO (OUTPUT):
Stereo Sync cable to your 3D controlling device such as an emitter or polarizer.
NOTE: RealD 3D sync cable recommended.

Using the 3D Test Pattern

Use the 3D internal test pattern
to confirm 3D mode, L/R
orientation, and GPO settings.
This pattern automatically
activates 3D mode and
increases frame rate by a factor
of 6:2.
NOTE: The test pattern will
flicker significantly due to its
low frame rate, and is not
recommended for synchronizing
projector processing with your
3D device.
Image breakup
Increasing the Dark Time beyond its maximum may cause image break-up.
No 3D effect
Certain settings in the Custom: 3D Control menu are likely reversed.
Ghosting / Cross-talk
Ghosting or cross talk indicates that the eyes are detecting portions of the opposing
frame due to an "out-of-sync" system. Adjust Dark Time and/or Output Delay so that
the projector's display output is synchronized with the gating (switching) of your
glasses.
: Choose the leading frame, left or right. Correct order
Use L/R Output Polarity to set whether the 3D sync
From the projector's GPIO port, connect your 3D
As desired, adjust the image color, etc.
