🔎 WHAT IS REFRESH RATE?

Refresh rate is measured in Hertz (Hz) and represents how often a display can update its image.

60Hz → up to 60 refreshes per second
90Hz → up to 90 refreshes per second
120Hz → up to 120 refreshes per second
144Hz → up to 144 refreshes per second

A higher refresh rate can provide smoother motion when the device, system and content support it.

The maximum advertised refresh rate is not necessarily the rate being delivered at every moment. Some devices dynamically switch between supported refresh rates depending on system conditions and power behavior.
