Section 3: Operation

USE CINEMA PROCESSING OR NOT? The cinema checkbox on the Custom 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 sources having high

resolution-and-frequency combinations. See examples in Table 3.3.

Table 3.3 Processing Path for DVI Sources (Examples)

NOTE: See Table 5.1 Compatible Non-Cinema DVI Sources (All Digital RGB 8-bit), on page 5-2 for a

more complete list.

Important! Attempting to use cinema processing when the incoming DVI vertical frequency is too high can

cause a TPC start-up error. Turn cinema option OFF, then cycle power OFF/ON.

CUSTOM: PAGE-1 MENU OPTIONS

Channel # Identifies/sets button# 1-32 for current Custom menu settings. To assign a new channel # for the

current Custom settings, select the desired # (display will also change) and press SAVE. Buttons

representing channels appear in order on the Main menu.

Channel Name Current name or title for a button identifying a source, such as a movie title or DVD. Select to

rename using pop-up keyboard. Up to 32 names can appear on the TPC Main menu (4 pages of 8).

Large Icon (button) Shows icon defined for current source. Click to assign a different icon.

Cinema Keep checked for most sources (default), ensuring that incoming data is processed using the com-

plete cinema path and scaled to fill the screen where possible. Currently cinema sources (A/B pro-

jector inputs) should always utilize the cinema path and scaling. Uncheck only for incoming DVI

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.

Use PCF Enter a check to use a pre-defined PCF for this source and prohibit further Custom 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 if you wish

to adjust the Custom settings-this is currently recommended for all cinema use.

Refresh Button Updates all Custom settings (such as Gamma, Target Color, etc.) to include any data newly added

to projector memory via DCP Librarian setup software or TPC Admin menus.

3D Button If present, the current channel is for a 3D display (set in 3D Control menu).

Reset Button Clear the current (or all) channel settings and return to factory defaults.

Input Identifies/sets the location/connection of the current source, such as cinema ports A or B, or a DVI

graphics port. Note that use of the twin and dual link DVI options requires special hardware. Refer

to Section 5

Non-Cinema Operation.

Data Format Specifies the source type (8-10-12-bit) and whether or not it is packed. The projector will process

the incoming signal according to the data format selected here. Note that available data formats

depend on which projector input is selected, and will reset to a default value if an input has not yet

been selected. Use of DVI-dual requires a separate adapter at the DVI connectors, and use of DVI-

twin requires a special source. Data format settings are not included in a PCF.
