Is refresh rate and Hz the same thing?

Yes, refresh rate and Hz refer to the same concept in the context of displays. Refresh rate, measured in Hertz (Hz), indicates how many times per second a screen can refresh the image it displays. For example, a refresh rate of 60 Hz means the screen refreshes 60 times per second. Higher refresh rates can lead to smoother motion and better visual performance, particularly in fast-paced content.
