常用示例
Generate a modeline
cvt [1920] [1080] [60]
Generate reduced blanking modeline
cvt -r [1920] [1080] [60]
Generate modeline with reduced blanking v2
cvt -r2 [2560] [1440] [144]
Generate verbose output
cvt -v [1920] [1200] [75]
说明
cvt calculates VESA Coordinated Video Timing (CVT) modelines for X11 display configuration. It outputs modeline parameters suitable for use with xrandr or in xorg.conf files. CVT is the standard formula for calculating display timing parameters from resolution and refresh rate. The tool generates timing values including pixel clock, horizontal and vertical sync parameters, and blanking intervals. Reduced blanking modes (-r, -r2) are designed for LCD displays and digital connections (HDMI, DisplayPort), using less bandwidth than traditional CRT-compatible timings. This enables higher resolutions and refresh rates over limited bandwidth connections.
