FRAME DELAY —
Set the number of lines delayed between the input signal and its
appearance on screen, keeping in mind that projector processing always adds one
frame of delay to the frame delay setting. For applications such as simulation, where
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.
NOTE: See separate Using 3D in Mirage manual provided for more information.
3D STEREO SYNC LOCKING
—
This option defines 1) whether or not the incoming
stereographic 3D signal locks to the vertical sync output so that signals are
synchronized, 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. Keep this adjustment OFF (default)
when you are not using the
Mirage 3D Stereo Sync Cable.
With your sync cable, Z-screen 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 2 (or 0), do not invert; if frame delay is 1 or 3, 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.
