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.

One piece of data consists
of 4 digits.
* If data is less than 4 digits, add a “0” (zero) to make it 4
digits.

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

ofthePICTUREmenu,orsendthecorrespondingRS-232C
command.
n
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.)
