NAME

6       cvt - calculate VESA CVT mode lines

SYNOPSIS

9       cvt [-v|--verbose] [-r|--reduced] h-resolution v-resolution [refresh]
10

DESCRIPTION

12       Cvt  is  a utility for calculating VESA Coordinated Video Timing modes.
13       Given the desired  horizontal  and  vertical  resolutions,  a  modeline
14       adhering  to the CVT standard is printed. This modeline can be included
15       in Xorg xorg.conf(5)

OPTIONS

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