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 ad-
hering 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
frequency signals, with a lower or equal dotclock. Not for
Cathode Ray Tube based displays though.
