The refresh rate refers 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. Refresh rate is important for various devices, including monitors, televisions, and smartphones. A higher refresh rate can enhance the viewing experience, especially in action scenes or while playing video games, where quick movements are common.
