What does 60 Hz mean on your LED TV?

All television signals use a series of still images that change frequently. By changing the still image fast enough, the appearance is of a moving image.

60Hz means that the image is updated 60 times each second. This is the standard refresh rate for television in North America, Japan and other regions that use NTSC color systems. In Europe, the refresh rate is 50Hz or 50 times each second.

A television will display an image at the refresh rate of the incoming signal. There are an increasing number of televisions that offer 100 or 120Hz refresh rates or even higher. The incoming signal is still updating the image at 50 or 60Hz but the television carries out complex calculations to create an image that would have been there if the camera had captured the intermediate image. Some are more successful than others. If the calculations are not carried out correctly, the result may look jerky. Done well, the image will appear to move more smoothly. The only way to judge is to look at the image on each television.
