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 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.
