Monitor Refresh Rate Test
Accurately measure your display’s refresh rate using real-time frame analysis
A smooth, crisp ball indicates a high refresh rate. Visible blur or stuttering typically means 60 Hz or below.

What Is Refresh Rate?
Refresh rate measures how many times per second your monitor redraws the image, expressed in Hertz (Hz). Higher refresh rates produce smoother motion, reduce ghosting, and lower perceived input latency — particularly important for gaming, video editing, and fast-moving content.
How This Tool Works
This tool uses the browser’s requestAnimationFrame API to precisely timestamp each rendered frame. By averaging the time intervals between frames over a rolling window, it calculates your display’s true refresh rate — independent of reported system settings.
