Note that with Graphics/HDTV processing mode (which the projector can select
automatically), the internal delay is fixed at 282 ±5µs in relation to the vertical sync,
thus special glasses may be required to prevent cross-talk. In addition, 3D displays
via Graphics/HDTV processing have a 2-frame delay, thus there is no need for the
TTL left/right inverter required with "Minimum Delay" processing (as described in
Hardware Requirements, below). For complete processing information, see 3.7,
Adjusting System Parameters and Advanced Controls.
A 3D-video signal is sent to the projector via analog cables such as:
N
3-wire RGB sync-on-green
N
4-wire RGB with composite sync
N
5-wire RGB with separate H-sync and V-sync
NOTE: Refer to 2.4, Source Connections for full details and illustrations.
Most 3D sources are compatible with the Mirage 10000. However, because 3D signal
formats currently available are optimized for display via older CRT (cathode ray
tube) technology, it is possible that you may encounter an unusual source having a
high pixel rate unsuitable for this projector. By reducing the blanking in such a
signal, you can lower its pixel rate enough to be compatible with the projector (i.e.,
under 160 MHz). This adjustment requires a high-end graphics workstation that
includes hardware and software tools for customizing video output timing parameters
(for example, the Silicon Graphics ONYX
Compiler software, which provides a .vfo file). Other similar workstations may also
provide the special video driver needed.

NOTE: Requires "Minimum Delay" processing mode. See also Customizing the
Input Signal later in this section.
N
Use a progressive RGB source with native resolution of 1024 x 768 (can be
cropped to 768 x 768 if desired). Higher resolution can be used, but edge
pixels will be cropped rather than the image resized to fit.
NOTE: Total number of lines in the image, including blanking > 780.
Total number of pixels-per-line, including blanking > 1168
N
96-120 Hz input frame rate
N
Pixel rate must be less than 160 MHz
N
Set Pixel Tracking to 1168 or higher.
N
Use "Minimum Delay" Processing Mode. Note that this option produces only
a single frame delay, disables resizing, keystone and the "Freeze Image"
options, and limits vertical and horizontal position ranges.
