Cvt is a utility for calculating VESA Coordinated Video Timing modes.
Given the desired horizontal and vertical resolutions, a modeline
adhering to the CVT standard is printed. This modeline can be included
in Xorg xorg.conf(5)
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
Warn verbosely when a given mode does not completely correspond
with CVT standards.
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.
This program is based on the Coordinated Video Timing sample implemen-
tation written by Graham Loveridge. This file is publicly available at
