1 | .TH CVT 1 __vendorversion__ |
| 2 | .SH NAME | |
| 3 | cvt - calculate VESA CVT mode lines | |
| 4 | .SH SYNOPSIS | |
| 5 | .B cvt | |
| 6 | .RB [ \-v | \-\-verbose ] | |
| 7 | .RB [ \-r | \-\-reduced ] | |
| 8 | .I h-resolution | |
| 9 | .I v-resolution | |
| 10 | .RB [ refresh ] | |
| 11 | .SH DESCRIPTION | |
| 12 | .I Cvt | |
| 13 | is a utility for calculating VESA Coordinated Video Timing modes. Given the | |
| 14 | desired horizontal and vertical resolutions, a modeline adhering to the CVT | |
| 15 | standard is printed. This modeline can be included in Xorg | |
| 16 | .B xorg.conf(__filemansuffix__) | |
| 17 | . | |

| 19 | .SH OPTIONS | |
| 20 | .TP 8 | |
| 21 | .BR refresh | |
| 22 | Provide a vertical refresh rate in Hz. The CVT standard prefers either 50.0, | |
| 23 | 60.0, 75.0 or 85.0Hz. The default is 60.0Hz. | |
| 24 | .TP 8 | |
| 25 | .BR \-v | \-\-verbose | |
| 26 | Warn verbosely when a given mode does not completely correspond with CVT | |
| 27 | standards. | |
| 28 | .TP 8 | |
| 29 | .BR \-r | \-\-reduced | |
| 30 | Create a mode with reduced blanking. This allows for higher frequency signals, | |
| 31 | with a lower or equal dotclock. Not for Cathode Ray Tube based displays though. | |
