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.

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).

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.

DEFINE SYNC DISPLAY LOCATION:

•Set L/R Display Reference to Not Used.

•Set

Display GPI to None.
