NAME
       cvt - calculate VESA CVT mode lines

SYNOPSIS
       /usr/bin/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(4)


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.
