12 Cvt is a utility for calculating VESA Coordinated Video Timing modes.
13 Given the desired horizontal and vertical resolutions, a modeline
14 adhering to the CVT standard is printed. This modeline can be included
15 in Xorg xorg.conf(5)
16
17
19 refresh Provide a vertical refresh rate in Hz. The CVT standard
20 prefers either 50.0, 60.0, 75.0 or 85.0Hz. The default is
21 60.0Hz.
22
23 -v|--verbose
24 Warn verbosely when a given mode does not completely correspond
25 with CVT standards.
26
27 -r|--reduced
28 Create a mode with reduced blanking. This allows for higher
29 frequency signals, with a lower or equal dotclock. Not for
30 Cathode Ray Tube based displays though.
