cvt - calculate VESA CVT mode lines
SYNOPSIS
/usr/bin/cvt [-v|--verbose] [-r|--reduced] h-resolution v-
resolution [refresh]
DESCRIPTION
Cvt is a utility for calculating VESA Coordinated Video Tim-
ing modes. Given the desired horizontal and vertical reso-
lutions, a modeline adhering to the CVT standard is printed.
This modeline can be included in Xorg xorg.conf(4)
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.
