PROGRAM:
NAME
xgamma - Alter a monitor's gamma correction through the X server
SYNOPSIS
xgamma [-display display] [-screen screen] [-quiet] [-version] [-gamma f.f | [[-rgamma
f.f] [-ggamma f.f] [-bgamma f.f]]]
DESCRIPTION
xgamma allows X users to query and alter the gamma correction of a monitor via the X video
mode extension (XFree86-VidModeExtension).
Note that the xgamma utility is obsolete and deficient, xrandr should be used with drivers
that support the XRandr extension.
If no value for the gamma correction is given via the -gamma or -rgamma/-ggamma/-bgamma
options, xgamma prints the current gamma correction of the display.
OPTIONS
-display display
This argument allows you to specify the server to connect to; see X(7).

allows you to select the screen you wish to change.
