Monitor Refresh Rate
Detect your monitor's refresh rate in your browser.
What Is a Monitor Refresh Rate Test?
A monitor refresh rate test detects how many times per second your display updates the image on screen, measured in hertz (Hz). The tool uses the browser's requestAnimationFrame API to count rendered frames over a sampling period and estimates your monitor's true refresh rate. Common results include 60 Hz for standard monitors, 144 Hz for mid-range gaming displays, and 240 Hz or 360 Hz for competitive esports screens. The test also reports a confidence level indicating how consistent the frame timing was during measurement. Knowing your actual refresh rate helps you verify that your display is running at its advertised speed and that your operating system settings are configured correctly.
How to Use the Monitor Refresh Rate Test
Click the start button to begin detection. The tool measures frame intervals over several seconds, so keep the browser tab in the foreground and avoid scrolling or switching windows during the test. When detection completes, you will see your refresh rate in Hz, the corresponding FPS value, and a confidence rating. High confidence means the frame timing was consistent and the result is reliable. If your result seems lower than expected, check that your OS display settings have the correct refresh rate selected — many monitors default to 60 Hz even if they support higher rates. Run the test again after changing settings to confirm the update took effect.
Why Your Monitor's Refresh Rate Matters
A higher refresh rate delivers smoother motion, reduced input lag, and less motion blur — all critical advantages in fast-paced gaming. The jump from 60 Hz to 144 Hz is immediately noticeable when moving the camera in any 3D game, and most players report that aiming feels significantly more responsive. However, the smoothness benefit only applies when your GPU can actually push enough frames to match the refresh rate. A 240 Hz monitor running a game at 80 FPS will not look smoother than a 144 Hz panel at the same frame rate. Verifying your actual refresh rate ensures you are getting the full performance you paid for and that no software setting is silently capping it.
Frequently Asked Questions
What is monitor refresh rate?
Refresh rate (measured in Hz) is how many times per second your monitor updates the image. 60Hz updates 60 times/second, 144Hz updates 144 times/second.
What is the difference between 60Hz and 144Hz?
144Hz is noticeably smoother than 60Hz, especially in fast-paced games. You'll see less motion blur, smoother mouse movement, and better target tracking.
How do I enable high refresh rate?
Go to Display Settings → Advanced Display → choose your desired refresh rate. In Windows, also check NVIDIA Control Panel or AMD Radeon Settings.
