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.
