4.8.1
Operation
Use the command as shown in the following examples.
Purpose: To switch the gamma coefficient of the gamma table “Custom1” to 2.1.
(Current setting: Gamma bank “Custom1”, Gamma coefficient “2.2”)
(1)
Transmit the data from the external controller to the projector as follows.
1: External controller →

4.8.2
Reference
Use the command as shown in the following examples.
Purpose: To confirm the current gamma coefficient of the gamma table “Custom2” of
the projector. (Current setting: Gamma bank “Custom2”, Gamma coefficient “ 1.8”)
(1)
Transmit the data from the external controller to the projector as follows.
1: External controller →
