To transfer the GAMMA user data
Use the user data transfer commands (UGRW, UGGW and UGBW). For each of the R, G and B colors, divide the total 512
pieces of user data into 16 blocks, and transfer 32 pieces of data with each command.
* If data is less than 4 digits, add a "0" (zero) to make it 4 digits.
* The checksum field is the character string (ASCII) data of lower-order one byte which indicates the sum of the block number
and 32 pieces of data in hexadecimal (0 to F).
Saving the GAMMA user data
Use the user data save command (UGSV) to save the transferred user data in the monitor.
If the data is not saved, it will be cleared when:
• The main power switch is off
• STANDBY MODE is LOW POWER and the monitor enters standby mode
Activating the GAMMA user data
To activate the transferred user data, select USER for GAMMA in the PICTURE menu, or send the corresponding control
command.
Checking the GAMMA user data
Use the user data read commands (UGRR, UGGR and UGBR) to return 512 pieces of user data for each of the R, G and B
colors. Divide the data into 16 blocks and return 32 pieces of data with each command. The value to be returned is not the value
stored in the monitor, but the value in the temporary memory for display. (These values are the same when the user data save
command (UGSV) above has been sent.)
TIPS
• The user data is not initialized by RESET of the PICTURE menu. To initialize the user data, use ALL RESET of the
FUNCTION menu.
The GAMMA user data initialize command (UGRS) allows the initialization of the user data only.
