1. NAME

cvt - calculate VESA CVT mode lines

2. SYNOPSIS

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

3. 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

xorg.conf(5) .

4. OPTIONS

R 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.

R -v | --verbose

        Warn verbosely when a given mode does not completely correspond with CVT standards.

R -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.
