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 resolu-
       tions, 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 kHz.  The CVT standard prefers  either  50.0,  60.0,  75.0  or  85.0kHz.   The
               default is 60.0kHz.

       -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.
