How frequently does a display update its image if it has a refresh rate of 120 Hz?

A display with a refresh rate of 120 Hz updates its image 120 times per second. The refresh rate is a measure of how many times per second the display can redraw the image on the screen. A higher refresh rate means smoother motion and can reduce motion blur, which is particularly beneficial for fast-moving visuals in video games, movies, and other multimedia applications.

When a display operates at 120 Hz, it effectively refreshes the screen image each cycle, meaning that within one second, it completes 120 refresh cycles. This characteristic is pivotal for ensuring that fast action appears fluid and clear, which is why displays with higher refresh rates are often preferred by gamers and professionals in fields that require precision in visual detail.
