NAME
     xgamma - Alter a monitor's gamma correction  through  the  X
     server

SYNOPSIS
     /usr/bin/xgamma [-display display] [-screen screen] [-quiet]
     [-gamma f.f | [[-rgamma f.f] [-ggamma f.f] [-bgamma f.f]]]

DESCRIPTION
     xgamma allows X users to query and alter the  gamma  correc-
     tion  of  a monitor via the X video mode extension (XFree86-
     VidModeExtension).

     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(5).

     -screen screen
             When multiple displays are configured  as  a  single
             logical  display,  this  option allows you to select
             the screen you wish to change.

     -quiet  Silence the normal output of xgamma

     -help   Print out the `Usage:' command syntax summary.

     -gamma f.f
             The gamma correction can either be defined as a sin-
             gle value, or separately for the red, green and blue
             components.  This  argument  specifies   the   gamma
             correction as a single value.

     -rgamma f.f
             This argument specifies the  red  component  of  the
             gamma correction.

     -ggamma f.f
             This argument specifies the green component  of  the
             gamma correction.

     -bgamma f.f
             This argument specifies the blue  component  of  the
             gamma correction.

ENVIRONMENT
     DISPLAY To get default host and display number.

BUGS
     This client changes the internal values of the gamma correc-
     tion  for  the  Xserver.  Whether  or  not  these values are
     respected depends on the video drivers.

     The gamma values are passed to the Xserver  with  3  decimal
     places of accuracy.
