 Proper 3D configuration defined in the Channel: 3D Control menu. Use an internal test pattern for
best results.

3.8.2 Hardware Setup

In dual projector configurations, each projector is essentially displaying a standard 2D image and the 3D
control functionality of the projector is not needed. Refer to the illustrations on the preceding pages for the
general hardware configuration supported. Use either an IR emitter to control gating in active glasses, or a
polarizing cell and Z-screen with passive glasses.
3.8.3 3D Instructions
NOTES: 1) Assume 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.
1. Connect two HD-SDI signals from a 3D media server to the projector's SMPTE cinema ports 292-A and
292-B. One carries left-eye data, the other right-eye data. Connect to either port; configure the projector to
multiply and interleave the L/R signals properly.
2. Set the frame rate. NOTE: CP2000-M/MR models can support full resolution (2k) 3D.
Both incoming frame rates are likely too slow for flicker-free 3D viewing and need to be increased within
the projector for at least 144Hz output. For example, a typical HD-SDI rate of 24Hz is still only 48Hz
when L/R are combined. In the Channel: 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 4:2 setting creates
four frames from two inputs (=96Hz), or a setting of 6:2 creates six frames from two inputs (=144Hz). The
resulting frame rate possible in the projector - with 24Hz full screen incoming signals, use a maximum 
factor of 5:2. NOTE: Frame rates for lower resolution displays can be increased by a larger ratio; 6:2 is
commonly used for most 3D features.
3. Define the 3D sync input location.
4. Define L/R dominance.
5. Define L/R sync display location.
6. Define sync output. Use 3D Sync Polarity to set whether the 3D sync signal output here matches the L/R
order of the incoming frames, or whether it is to be inverted - i.e., reversed (R/L). Then set the Display
GPI according to which of the projector's GPIO outputs is currently wired to the emitter or polarizer.
7. Connect GPIO (output). From the projector's GPIO port, connect the 3D stereo sync cable to the 3D
controlling device, such as an emitter or polarizer. NOTE: RealD 3D sync cable recommended.
