Look Index

This command sets the current system look. System looks shall be designed and configured via DLP Composer tool. System look determines the current group of sequences and color points to be loaded. This command also initiates the source definition change that corresponds to new look index.

Predefined test pattern number to be displayed

This command will set one of the pre-defined test patterns stored in flash (configured using DLP Composer tool). The function selects a pattern to load from flash into the test pattern generator hardware. The information retrieved from the flash includes pattern definition, color definition, and the resolution. The pre-defined patterns are included in the flash configuration data. Set Display command must be called to switch the display mode from other modes to TPG prior to or after this command .
