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.
