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.
