Calculating...
Refresh rate, measured in Hertz (Hz), is the number of times your screen updates with a new image each second. A higher refresh rate means smoother motion, as more frames are displayed in the same amount of time.
For gaming and fast-paced video, a higher Hz (like 120Hz or 144Hz) provides a significant competitive advantage by reducing motion blur and input lag. Our tool offers the most accurate way to check your screen's precise hertz instantly, with a zero-clutter, ad-free experience.
