preserve full screen display. 6:2 is commonly used for most
3D features which comprise 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 right). 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. A 4:2
setting creates 4 frames from 2 inputs (=96 Hz), or 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 rates for lower resolution displays can be increased by a larger
ratio. 6:2 commonly used for most 3D features.

For dual inputs, set the L/R Input Reference option to

For dual inputs, set the Input GPI to None.

These two settings tell the rest of your 3D system that incoming 3D stereo sync
information 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# is used (i.e., according to your GPIO cable wiring).
