IMAGE CONTROLS
After you have made your adjustments with the Input Commands, you can then
adjust the image controls for each input.
Command Arguments Description
BRIght <input# | ALL> <-500…500> Sets brightness value of the selected input. The ALL
argument sets brightness for all four inputs.
Factory default: 0
ChromaKey <ON | OFF> Enables or disables chroma key mode. ChromaKey is not
available in Free-run display mode. The effect of the
chroma key is set with the ChromaKeyColor command.
ChromaKeyColor <-270...1250> <-270...1250>
<-270...1250> <-270...1250>
<-270...1250> <-270...1250>
This command sets the range of colors for the chroma key
circuit. The chroma key works by replacing any color
within the acceptance range by active video. The
parameters are interpreted as follows: rmin rmax gmin
gmax bmin bmax, representing the minimum and
maximum values for red, green, and blue to fall within the
acceptance range (see Appendix B for details). If a red,
green, or blue color range is specified such that min > max,
the command is ignored.
Example—make saturated cyan (full amplitude green and
full amplitude blue with no red) the key color:
>CKC -270 100 600 1250 600 1250
The background host computer becomes transparent
wherever a saturated cyan color is present; any underlying
windows show through.
ChromaKeyColor can be set whether or not ChromaKey is
enabled.

argument sets contrast for all four inputs.
