Refresh Rate Test
This test measures your display's actual refresh rate by counting frames per second.
Common Refresh Rates
How to Use This Test
- Wait a few seconds for the test to stabilize after the page loads -- the refresh rate and frame time will update automatically.
- Compare the detected refresh rate with your monitor's advertised specification to confirm it is running correctly.
- Watch the moving box animation to visually confirm smooth motion at your display's refresh rate.
What This Test Checks
This refresh rate test uses the browser's requestAnimationFrame API to count how many frames your display renders per second, giving you an accurate real-time measurement.
- Actual display refresh rate in Hz (hertz) as reported by the browser
- Frame time in milliseconds, showing the interval between each frame
- Visual motion smoothness through an animated element
- Whether your monitor is running at its full rated refresh rate
Troubleshooting
If you're having issues with the test results:
- Ensure your operating system display settings are set to the highest available refresh rate for your monitor.
- Check that your HDMI or DisplayPort cable supports your monitor's maximum refresh rate.
- Disable any battery-saving or power management modes that may throttle the display.
- Close other browser tabs and resource-heavy applications to avoid frame drops during the test.
Frequently Asked Questions
Why does my refresh rate show lower than expected?
Your browser or operating system may be limiting the refresh rate. Check your display settings to ensure the highest refresh rate is selected, disable any power-saving modes, and make sure your cable (HDMI/DisplayPort) supports the desired refresh rate.
What refresh rate do I need for gaming?
For casual gaming, 60Hz is sufficient. Competitive gamers typically prefer 144Hz or higher for smoother motion and reduced input lag. Professional esports players often use 240Hz or 360Hz monitors for the ultimate competitive edge.
Is there a difference between refresh rate and frame rate?
Yes. Refresh rate (measured in Hz) is how many times per second your monitor updates the image. Frame rate (measured in FPS) is how many frames your GPU renders per second. Ideally, your frame rate should match or exceed your refresh rate for the smoothest experience.
