Examples
Use a custom color table:
(CCA+SLCT 3)
Reset values to "HD Video (ITU-R BT.709)":
(CCA+COPY 2)
Change the x-coordinate of the custom color table to 0.6753:
(CCA+RDCX 6753)

Description
Sets the native color primaries for the
projector using the x,y coordinate form,
scaled by a factor of 10,000. For example,
an x value of 3350 corresponds to x=0.3350
in the CIE 1931 chromaticity scale.
This command is only available if the video
electronics are on and Max Drives is
selected. It is only available to a service
user.
Resets the native color primary settings to
their defaults.
If primary settings have not been saved
(CCA+SAVE), this resets the primary
settings to hard-coded defaults.
This command is only available if video
electronics are on. It is only available to a
service user.
Saves the current primary settings (for
example, CCA+RDPX, and so on) as the new
default color primary settings.
Save these settings after calibrating the
color primaries (such as measuring the
primary x,y coordinates using a
spectroradiometer or similar equipment).
This command is only available if video
electronics are on. It is only available to a
service user.

Values
The valid range for each value
depends on which of the red,
green, blue, or white point is
being adjusted.
