COLOR TEMPERATURE —
Adjust to apply a specific and accurate color temperature to
all displays. Color temperatures are expressed in degrees Kelvin (3200-9300K), and
utilize different combinations of the projector’s original native color primaries to
produce a “coloration” or cast (reddish or bluish) in images—the lower the
temperature, the more reddish the cast; the higher the temperature, the more bluish the
cast. Note that the slidebar is enabled only if you have a source connected and have
selected “Color Temperature” in the adjacent “Select Color Adjustment” pull-down
list in the Advanced Image Settings menu.
FRAME DELAY
— Set the interval of delay desired between the input signal and its
appearance on screen. 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
frame delay setting of two (or multiple of two) may be more useful. Delay may vary
between sources.
DARK INTERVAL
—
When displaying 3D (stereographic) images, adjust Dark Interval
to artificially increase the amount of dark time between displayed frames. 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 3.9, 3D Images for a full explanation of Dark Interval use.
3D STEREO SYNC
—
This option defines 1) whether or not the incoming 3D
(stereographic) 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 left/right
image data is seen by the intended eye. 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 (this cable replaces the
need for a separate TTL inverter as described in 3.9, 3D Images). 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 3.9,
3D Images, 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 3.9, 3D Images for a full
explanation of 3D Stereo Sync use.
