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 kHz. The CVT standard prefers either 50.0, 60.0, 75.0 or 85.0kHz.
The default is 60.0kHz.
- -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.
