Understanding Refresh Rates
To grasp the significance of 120Hz, it’s essential to understand what refresh rates are and how they affect the viewing experience. The refresh rate of a TV refers to how many times the screen updates with new images per second. It’s measured in Hertz (Hz), with common refresh rates including 60Hz, 120Hz, and 240Hz. A higher refresh rate means the TV can display more frames per second, which can lead to a smoother and more realistic picture, especially in fast-paced content like sports and action movies.
The Impact of Higher Refresh Rates
Higher refresh rates, such as 120Hz, offer several benefits over the standard 60Hz. Reduced motion blur is one of the most significant advantages. Motion blur occurs when the TV struggles to keep up with fast-moving objects on the screen, resulting in a blurry trail behind them. With a 120Hz refresh rate, the TV updates the image twice as often as a 60Hz TV, minimizing motion blur and providing a clearer picture. This is particularly noticeable in scenes with rapid camera movements or fast-paced action sequences.
