cvt - calculate VESA CVT mode lines
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
- 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.
- 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 implementation
written by Graham Loveridge. This file is publicly available at
