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 improved visual clarity, especially in fast-paced content like video games or sports. The refresh rate is crucial for reducing motion blur and improving the overall viewing experience. It works in conjunction with other factors, such as response time and frame rate, to enhance the performance of devices like monitors, televisions, and gaming consoles, including PlayStation and Xbox.
