DARK INTERVAL — Adjust Dark Interval to artificially increase the amount of dark
time between displayed frames for stereographic 3D images. Higher settings provide
more time for shutters in 3D glasses to open/close, ensuring that each eye sees the full
display intended for it. Symptoms of cross talk and/or color artifacts can indicate 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.
NOTE: See separate Using 3D in Mirage
manual provided for more information.
3D SYNC OUTPUT — This option defines 1) whether or not the sync will be frame
doubled on the output, and 2) whether or not the 3D frames must be inverted, i.e.
swapped left-with-right. The correct setting ensures that the projector’s 3D display of
left/right frames is synchronized with the rest of the 3D system components so that the
intended eye sees the left/right image data. Select the option corresponding to your 3D
source connections and timing, and use only if the Mirage 3D Stereo Sync Cable is
connected between the projector’s GPIO port and a server. Only the last projector in
the chain that is connected to the emitter will choose one of the emitter choices; all
other projectors will choose ‘To Next Input’. Choose OFF when you are not using the
Mirage 3D Stereo Sync Cable.
With your sync cable and, if desired, emitter connected as described in the Using 3D
in Mirage manual, select the option suited to your 3D configuration (see above). If
Frame Delay is two (or 0), do not invert; if frame delay is one or three, invert.
Generally, an “Unlocked” setting is synchronized with the incoming L/R signal rather
than the vertical sync output, and may be needed only with multi-projector
installations in which the vertical sync outputs vary.
NOTE: See separate Using 3D in Mirage
manual provided for more information.
3D SYNC INPUT —
Define which of the
Mirage 3D Stereo Sync
Cable’s input connecters
is routed from your
server. Use only if the
cable is present. Only
the first projector,
possibly connected to
external sync, will choose any of these selections. Every other projector will be
getting sync from the previous projector on Input A or Input B.
