• LUT-CLUT*: A "Complex Look-up Table" retrieved from internal electronics.
*NOTE: Components marked with an asterisk (*) are part of any pre-defined PCF (Projector Configuration
File) that controls image processing for a given source. When the "Use PCF" checkbox is checked, these
components disappear from the Channel menu and are protected from further change.
• Re-sync: Activate to enable the re-synchronization function associated with the Pull Down Sequence (see
below). In certain cases it is useful to disable re-synchronization when the time code is not running at the
proper rate, such as when a jog control is being used with a tape machine.
• Pull Down Sequence: Use the drop-down menu to specify the pull down sequence to apply. Typically, a 2:2
Pull Down Sequence is used. Pull down is used to distribute film content to video. Since film is projected at
24 frames per second and video typically at 60 pictures per second, the film content must be converted to
video for optimal display.
• Pull Down Offset: Identifies and sets the frame offset from Fields 1 to 5.
• SMPTE Field Bit: Use the drop-down menu to select the field offset polarity.
• Use PCF: Enter a check to use a pre-defined PCF for this source and prohibit further Channel adjustments
(the PCF components of Source, Color Space, Gamma, LUT-CLUT and Target Color will disappear), then
select the desired PCF from the "Predefined Configurations" list. Clear the checkbox to adjust the Channel
settings - this is currently recommended for all cinema use.
When to Use a PCF?
The availability of functions in the Channel: Page 1 menu depends on whether you choose to utilize pre-
defined configuration files (PCFs) already downloaded to projector memory, or whether you prefer to
implement your own settings. PCFs can be created using the DLP Application then downloaded to the
projector. By enabling the Use PCF checkbox a pre-defined PCF can be selected and implemented. Most
applications; such as cinema, post production and "alternative" or "non-cinema" displays require 1 or
more display parameters be individually adjusted. In this case, clear the Use PCF checkbox.
• Cinema: Keep checked for most sources (default), ensuring that incoming data is processed using the
complete cinema path and scaled to fill the screen where possible. Currently cinema sources (292 A/292 B
projector inputs) should always utilize the cinema path and scaling. Uncheck only for incoming DVI-D
having a frame rate >60 Hz (if SXGA) or >48 Hz (if 2048 x 1080), as the cinema pixel clock rate is limited
to 110 MHz.
When to Use Cinema Processing?
The Cinema checkbox in the Channel: Page 1 menu determines if the incoming signal is processed using
the projector's full cinema path, which enables image scaling and color correction, but restricts resolution-
and-frequency combinations. If unchecked, most of the projector's Processor Board functionality is by-
passed—this disables scaling and color correction, but is compatible with higher resolution-and-frequency
combinations. Generally, use non-cinema processing with DVI-D sources having high resolution-and-fre-
quency combinations. Refer to
ema DVI-D Sources.
