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  fre-
	     quency signals, with a lower or equal dotclock. Not for Cathode Ray
	     Tube based displays though.

SEE ALSO
     xorg.conf(5), gtf(1)
