3.10.5 3D Instructions
NOTES: 1) Assumes a full 2048 x 1080 display, and 3D enabled in the Custom: 3D Control menu.
2) 3D stereo sync or reference signal is part of input signal, matching the vertical sync.

Hardware Instructions

1. Connect two HD-SDI signals from a 3D media server to the projector's SMPTE cinema ports A and B.
One carries left-eye data, the other right-eye data. Connect to either port; you will configure the projector
to multiply and interleave the L/R signals properly.

Web User Interface Instructions

1. Click Enable.
2. SET THE FRAME RATE:
NOTE: 6:2 is commonly used for most 3D features which are comprised of resolutions slightly less than
2048 x 1080.
Both incoming frame rates are likely too slow for flicker-free 3D viewing, and need to be increased within
the projector for at least 96 Hz output. For example, a typical HD-SDI rate of 24Hz is still only 48 Hz
when L/R are combined (see Figure 3-56). In the Custom: 3D Control menu, set the desired Frame Rate
N:M ratio-or number of frames displayed per number of frames for complete data. For example, a setting
of 6:2 creates 6 frames from 2 inputs (=144 Hz). The resulting frame rate cannot exceed the maximum
frame rate possible in the projector-with 24 Hz full-screen incoming signals, use a maximum factor of 5:2.
NOTE: Frame rate multiplication less than 6:2 may flicker at slow incoming frame rates.
3. DEFINE 3D SYNC INPUT LOCATION:
For dual inputs,
• Set L/R Input Reference option to Active
Port: A/B =L/R or vice versa.
• Set the Input GPI to None.
These two settings tell the rest of your 3D
system that incoming 3D stereo sync infor-
mation is included with the two L/R image
data inputs rather than routed separately to
the GPIO port.
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 number is used
(i.e., according to your GPIO cable wiring).
4. DEFINE L/R DOMINANCE:
For the Input Frame Dominance, choose the leading frame, left or right. Correct order 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.
