"120 fps" stands for "120 frames per second," which is a measure of how many individual images (or frames) are displayed in one second of video. Higher frame rates like 120 fps can create smoother motion and more fluid visuals, making them popular in gaming and high-definition video playback. This is especially beneficial for fast-paced action scenes, where clarity and detail are crucial. Many modern displays, such as televisions and computer monitors, support 120 fps, allowing users to experience content at this enhanced frame rate. Additionally, some video games are designed to run at 120 fps, providing a more immersive experience for players.
