The term "144 Hz" refers to the refresh rate of a display, indicating how many times per second the image on the screen is updated. A refresh rate of 144 Hz means the screen refreshes 144 times in one second, resulting in smoother motion and improved clarity, especially in fast-paced activities like gaming or watching sports. Displays with a 144 Hz refresh rate are popular among gamers and professionals who require high-performance visuals. This technology is often found in gaming monitors and high-end televisions, providing a more responsive experience compared to standard 60 Hz displays.
