Most 3D signal formats currently available are optimized for display via CRT
(cathode ray tube) technology, thus they have high pixel rates unsuitable for this
projector. By reducing the blanking in these signals, however, you can lower their
pixel rate enough to be compatible with the projector (under 160 MHz). Typically, a
high-end graphics workstation that includes hardware and software tools for
customizing video output timing parameters can produce the requisite 3D signals, as
can a PC running Windows
your 3D displays must originate from either of these sources. The Silicon Graphics
TM
ONYX workstation is an example—it includes Video Format Compiler software
capable of properly modifying "timing" in the signal for use in the projector (it
provides a .vfo file). Other similar workstations may also provide the special video
driver needed.
NOTE: Not all systems include the hardware/software necessary for reconfiguring
the 3D video output timing parameters—these sources cannot be used with the
projector.
In addition, this projector requires the following conditions for 3D work at these
higher frame rates:
3D Source Requirements and Conditions
•
Use a progressive RGB source with native resolution of 1280 x 1024 (can be
cropped to 1024 x 1024 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 > 1036.
Total number of pixels-per-line, including blanking > 1424
•
96-108 Hz input frame rate
•
Pixel rate must be less than 160 MHz
•
Set Pixel Tracking to 1424 or higher.
•
Use "Minimum Delay" Processing Mode. Note that this option produces only
a single frame delay, disables resizing and the "Freeze Image" option, and
limits vertical and horizontal position ranges.
See Customizing the Input Signal later in this section.
