NAME
cvt - calculate VESA CVT mode lines
SYNOPSIS
cvt [-v|--verbose]
[-r|--reduced] h-resolution
v-resolution [refresh]
DESCRIPTION
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
OPTIONS
- 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.
