Coordinated Video Timings (VESA-2003-9) is a standard by VESA which defines the timings of the component video signal. Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions.
The parameters defined by standard include horizontal blanking and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync polarity.
The standard was adopted in 2002 and superseded the Generalized Timing Formula.
CVT specifies a mode which uses reduced blanking intervals, saving video signal bandwidth for modern LCD monitors which are not based on cathode ray tubes anymore. This mode is currently only defined for vertical frequency of 60 Hz.
