What do I need to know about TV refresh rates?
This rate is measured in hertz (Hz) and expresses the amount of times per second the image is refreshed on the screen. All you really need to know about refresh rates is that a higher one is preferable. Although 60 Hz is standard, it can produce some blur when there's a lot of fast motion on the screen, such as when watching sports or fast-paced fight scenes. Ideally, we'd recommend a TV with a minimum rate of 120 Hz.
