Refresh rates refer to the number of times a display updates its image per second, measured in hertz (Hz). For example, a refresh rate of 60 Hz means the screen refreshes 60 times each second. Higher refresh rates, such as 120 Hz or 240 Hz, can provide smoother motion and reduce blurring, making them popular for gaming and fast-paced video content. The refresh rate is crucial for devices like monitors, televisions, and smartphones. A higher refresh rate can enhance the viewing experience, especially in action scenes or competitive gaming, where quick movements are common. However, the benefits may depend on the content being displayed and the capabilities of the graphics card.
