NAME
       cvt - calculate VESA CVT mode lines

SYNOPSIS
       cvt [-v|--verbose] [-r|--reduced] h-resolution v-resolution [refresh]

DESCRIPTION
       Cvt  is	a utility for calculating VESA Coordinated Video Timing modes.
       Given the desired  horizontal  and  vertical  resolutions,  a  modeline
       adhering	 to the CVT standard is printed. This modeline can be included
       in Xorg xorg.conf(5)


OPTIONS
       refresh Provide a vertical  refresh  rate  in  Hz.   The	 CVT  standard
	       prefers	either	50.0,  60.0,  75.0  or 85.0Hz.	The default is
	       60.0Hz.

       -v|--verbose
	       Warn verbosely when a given mode does not completely correspond
	       with CVT standards.

       -r|--reduced
	       Create  a  mode	with reduced blanking.	This allows for higher
	       frequency signals, with a lower	or  equal  dotclock.  Not  for
	       Cathode Ray Tube based displays though.
