Parameters
Data length: 512
The gamma data has 256 adjustment points composed of binary data.
The byte order is little endian.
When the projector is not powered on and it receives the command, the projector ignores the command and does not respond.
When the gamma table of the projector is not “Custom1,”Custom2or Custom3” and the projector receives the command, the
projector ignores the command and does not respond.
When the projector receives a gamma data by operation command, the projector saves the gamma data on proper area of
EEPROM immediately.
If the projector receives gamma data larger than 512 bytes, it is judged as invalid data and the projector does not respond.
The curve is combination of the curve on the OSD and the table (Normal/A/B/C/D) in the video processor.
