+.SH NAME
+xgamma - Alter a monitor's gamma correction for XFree86
+.SH SYNOPSIS
+.B "xgamma"
+[-display \fIdisplay\fP] [-screen \fIscreen\fP] [-quiet]
+[-gamma f.f | [[-rgamma f.f] [-ggamma f.f] [-bgamma f.f]]]
+.SH DESCRIPTION
+.PP
+.B xgamma
+allows X users to query and alter the gamma correction of a monitor via
+the XFree86 X server video mode extension (XFree86-VidModeExtension).
+.SH OPTIONS
+.PP
+.TP 8
+.B "-display \fIdisplay\fP"
+This argument allows you to specify the server to connect to; see \fIX(__miscmansuffix__)\fP.
+.PP
+.TP 8
+.B "-screen \fIscreen\fP"
+When multiple displays are configured as a single logical display, this option
+allows you to select the screen you wish to change.
+.PP
+.TP 8
+.B "-quiet"
+Silence the normal output of
+.B xgamma
+.PP
+.TP 8
+.B "-help"
+Print out the `Usage:' command syntax summary.
+.PP
+.TP 8
+.B "-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
+.B xgamma
+returns the current gamma correction of the display.
+.PP
+.TP 8
+.B "-rgamma f.f"
+This argument specifies the red component of the gamma correction.
+.PP
+.TP 8
+.B "-ggamma f.f"
+This argument specifies the green component of the gamma correction.
+.PP
+.TP 8
+.B "-bgamma f.f"
+This argument specifies the blue component of the gamma correction.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+To get default host and display number.
+.SH BUGS
+.PP
+This client changes the internal values of the gamma correction for the
+Xserver. Whether or not these values are respected depends on the video
+drivers.
+.PP
+The gamma values are passed to the Xserver with 3 decimal places of
+accuracy.
