the feeling of “real time” image response is a priority, a minimum setting is usually
preferable. For projectors capable of 3D (stereographic) applications where
alternating left-right frames must be synchronized with the corresponding L/R
shutters in 3D glasses, a total frame delay setting of two (or multiple of two) may be
more useful. If set too high or low, frame locking will not be possible—most sources
require approximately 50 lines of delay to ensure frame locking.
NOTE:
See separate Using 3D in Mirage manual provided for more information.
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.

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.
