8.0 ADJUSTING THE IMAGE
R599791 - FORCE 3D User Manual 61
The 3D sync signal is generated by the 3D source to insure left/right eye content is synchronized to the projector
and you. The projector has the ability to physically connect to two different sources. Ensure that the correct 3D sync
input is selected (either Input A or Input B) with each 3D signal source. If none/internal is selected the projector will
generate the sync internally and content will be displayed; however, there is a 50% chance that the content will be
displayed with the left/right eyes swapped (from the remote, press FUNC 6-9 to swap the eyes).

3D Sync Output
This option defines whether the 3D Sync is output and controls how it is processed. It is only valid when an optional
cable is used to connect stereo 3D signals to the projector via the GPIO port.
When there is no 3D signal, Sync Output should be 'Off'. Typically only the last projector in the 3D Stereo cable
chain is connected to the emitter and should specify 'To Emitter'. All other projectors should select 'To Next Input' if
other projectors are used in the chain.

3D Stereo Sync Delay
Adjust the output 3D emitter delay (in milliseconds) to match the active glasses to the L/R frames of the projector.
Proper adjustment of this delay will eliminate cross talk and odd colors caused by timing differences between the
glasses and the projected image. Your specified delay is added after sync locking.
3D Test Pattern
Enables a 3D test pattern for diagnostics. The scrolling diagonal lines indicate how well left and right are
synchronized. If ghosting is occurring the input may have to be switched or inverted. Adjustments to the emitter
delay can also help correct the synchronization. To verify that your 3D is setup correctly, a small set of “L”s will be
visible when you close your right eye and a small set of “R”s will be visible when you close your left eye.
Frame Locking
Enable or disable Frame Lock. When set to Frame Lock, if possible output image frames are locked to the input.
When Locked, the output is always locked to the primary input and never the secondary image, when using Dual
input 3D. Free Run sets the output to close to 60Hz for all sources. This control must be set to locked if a 3D-Stereo
signal is used.
Set Frame Delay
Delays the output signal timing relative to the input signal timing by a fraction of a frame, and up to several frames.
The minimum latency can vary based on the amount of scaling applied to the image. When using keystone or
warping, an additional latency is required, depending on the amount of warp. The control is only available when the
input signal is frame locked. In free run mode, or in cases where the signal cannot be frame locked, the minimum
latency defined by the scaling and keystone/warp is applied to the signal.
This function is not used in Interleaved 3D mode. Each eye receives a selected input and no 3D sync input
is required.
