Many TV manufacturers come up with various parameters that should characterize the quality of the image on the TV. Including Vizio was invented parameter Effective Refresh Rate. On the one hand, the frequency of updating the image on the screen, reports on how often the frames on the TV screen change. But Vizio in the specifications of the TVs indicates the parameter Effective Refresh Rate. This parameter has values of 240Hz, 120Hz, 60Hz.
Effective Refresh Rate is a virtual parameter invented by Vizio and it says that the image on the screen for the viewer will look like an image with a frame rate of 240Hz.
In fact, this parameter is overestimated and should be understood if the technical characteristics indicate.
Effective Refresh Rate 240Hz – the TV has a matrix with which supports 120 frames per second. Color depth 10 bits. Dimming zones 48-256.
Effective Refresh Rate 120Hz – the TV has a matrix that supports a frame change of 60 per second, but with a color depth of 8 bits + FRC or 10 bits and the matrix supports local dimming, but of 16-24 dimming zones.
Effective Refresh Rate 60Hz – a TV set with a matrix with a color depth of 8 bits or a matrix of 8 bits + FRC. But these are the simplest matrices they have no support for local dimming.
Effective Refresh Rate – this parameter shows the quality of the image on the TV, taking into account the type of screen matrix and has nothing to do with the actual frame rate.
