A 144Hz monitor is a display that refreshes the image on the screen 144 times per second. This high refresh rate provides smoother visuals, making it ideal for fast-paced activities like gaming and watching action movies. It reduces motion blur and enhances the overall viewing experience. These monitors are particularly popular among gamers because they can display more frames per second, resulting in a more responsive and immersive experience. To fully benefit from a 144Hz monitor, a compatible graphics card is necessary to deliver the higher frame rates that take advantage of the monitor's capabilities.
