Description

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.
