NAME¶

cvt - calculate VESA CVT mode lines

SYNOPSIS¶

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

DESCRIPTION¶

Cvtis a utility for calculating VESA Coordinated Video Timing modes. Given thedesired horizontal and vertical resolutions, a modeline adhering to the CVTstandard is printed. This modeline can be included in Xorgxorg.conf(5)

OPTIONS¶

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 CVTstandards.

-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.
