3D Mode: Select the mode of your 3D operation.
Off: 3D operation is disabled.
Native: All content is shown at a native frame rate of 96 - 120 Hz input and output.
Frame Doubled 3D: 3D Content from a single 48-60Hz signal (24/30Hz per eye) are displayed twice to
provide a 3D content to be viewed at 96-120Hz.
Dual Input 3D: Content from two independent 48-60Hz 'passive' frame locked sources are interleaved
into a native 96-120Hz native frame rate. This requires and optional input module and both signals must be
from the same signal type.
Dark Interval: Artificially increases the amount of dark time between displayed frames for stereoscopic 3D
images. Higher settings provide more time for shutters in 3D glasses to open and close, ensuring that each eye
sees the full display intended for it. Symptoms of cross talk or color artifacts can indicate the need for
adjustment. The Dark Interval range of adjustment depends on the vertical frequency of your source-the higher
the frequency, the smaller the range. Default setting is 2.5mS.
3D Sync Input: 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
receives a selected input and no 3D sync input is required.
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.
