   2 .SH NAME
   3 cvt - calculate VESA CVT mode lines
   4 .SH SYNOPSIS
   5 .B cvt
   6 .RB [ \-v | \-\-verbose ]
   7 .RB [ \-r | \-\-reduced ]
   8 .I h-resolution
   9 .I v-resolution
  10 .RB [ refresh ]
  11 .SH DESCRIPTION
  12 .I Cvt
  13 is a utility for calculating VESA Coordinated Video Timing modes.  Given the
  14 desired horizontal and vertical resolutions, a modeline adhering to the CVT
  15 standard is printed. This modeline can be included in Xorg
  16 .B xorg.conf(__filemansuffix__)

  19 .SH OPTIONS
  20 .TP 8
  21 .BR refresh
  22 Provide a vertical refresh rate in Hz.  The CVT standard prefers either 50.0,
  23 60.0, 75.0 or 85.0Hz.  The default is 60.0Hz.
  24 .TP 8
  25 .BR \-v | \-\-verbose
  26 Warn verbosely when a given mode does not completely correspond with CVT
  27 standards.
  28 .TP 8
  29 .BR \-r | \-\-reduced
  30 Create a mode with reduced blanking.  This allows for higher frequency signals,
  31 with a lower or equal dotclock. Not for Cathode Ray Tube based displays though.
