SYNOPSIS
       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 correction of a mon‐
       itor via the X video mode extension (XFree86-VidModeExtension).

OPTIONS
       -display display
               This  argument  allows you to specify the server to connect to;
               see X(7).


       -screen screen
               When multiple displays are configured as a single logical  dis‐
               play,  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  single  value,
               or  separately  for  the  red,  green and blue components. This
               argument specifies the gamma correction as a single  value.  If
               no  value  for the gamma correction is given xgamma returns the
               current gamma correction of the display.


       -rgamma f.f
               This argument specifies the red component of the gamma  correc‐
               tion.


       -ggamma f.f
               This  argument  specifies the green component of the gamma cor‐
               rection.


       -bgamma f.f
               This argument specifies the blue component of the gamma correc‐
               tion.

ENVIRONMENT
       DISPLAY To get default host and display number.
