NAME

6       cvt - calculate VESA CVT mode lines

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

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