What Is Refresh Rate?

Refresh rate, measured in Hertz (Hz), indicates how many times per second your screen redraws its image. A 60Hz display refreshes 60 times per second, while a 144Hz display refreshes 144 times per second. Higher refresh rates create smoother motion, less motion blur, and lower input lag.

Common Refresh Rates

60Hz — Standard for most displays. Suitable for everyday tasks and office work.
90Hz — Smooth experience for scrolling and animations. Common on mid-range phones.
120Hz — Found on flagship phones (iPhone Pro and iPhone 17, Samsung Galaxy), iPad Pro, PS5, Xbox Series X|S, and gaming laptops.
144Hz — The sweet spot for PC gaming monitors.
240Hz+ — Ultra-smooth for competitive esports and professional gaming.
