cvt

calculate VESA CVT mode lines

cvt [-v|--verbose] [-r|--reduced] h-resolution v-resolution [refresh]

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.
