Best smart TV in India is constantly refreshing itself, even if we aren't aware of it. The number of times per second that a new image is drawn on the screen is called a refresh rate, and it is measured in Hertz (Hz). The screen refreshes itself 60 times per second at a 60Hz refresh rate, while the screen refreshes itself 120 times per second at a 120Hz refresh rate. This should not be confused with frame rate, which is the number of times the source sends a new frame every second in an online smart LED TV. So, if your source displays 60 frames per second, your TV should refresh itself 60 times per second to match the refresh and frame rate, or motion will appear blurry.
