120fps, or 120 frames per second, refers to the rate at which images are displayed in a video. In this context, a frame is a single image, and 120fps means that 120 individual images are shown every second. This high frame rate can create smoother motion and more fluid visuals, making it particularly popular in gaming and high-action films. Many modern displays, such as televisions and computer monitors, support 120fps, allowing viewers to experience content as intended by creators. Additionally, some video games are designed to run at this frame rate, enhancing the overall gaming experience by providing more responsive controls and clearer motion.
