Screen Refresh Rate (Hz) Test
- What is my refresh rate? This test measures your browser's FPS and shows your screen's Hz in seconds.
- Stuck at 60Hz? Enable 120/144Hz in OS display settings and use a DP or HDMI 2.0/2.1 cable.
- Mobile supported? Yes—works on iPhone and Android high-Hz screens in any browser.
- Is this FPS or Hz? The browser's FPS is typically capped by your display's Hz, so FPS ≈ Hz.
Curious 'what is my refresh rate'? Our free online Hz test instantly measures the frames per second (FPS) of your monitor, display, or mobile screen.

If your result is lower than expected, enable higher Hz in system settings and use a DisplayPort or HDMI 2.0/2.1 cable.
For accurate results, ensure no other demanding applications are running.
How to Use This Hz Test
- Prepare: For the most accurate result, close any demanding applications or browser tabs that could slow down your computer.
- View Result: The test starts automatically when the page loads. Your screen's estimated refresh rate is displayed in the box above in real-time.
- Observe: Watch the moving bar in the "Visual Indicator" to see a representation of your screen's smoothness.
- Confirm: After a few seconds, the final, stable refresh rate will be shown. You can click "Test Again" to re-run the measurement.
What is Screen Refresh Rate?
The refresh rate of a display, measured in Hertz (Hz), is the number of times per second the screen hardware refreshes its image. Whether you are running a monitor Hz test for a gaming PC, a display Hz test for a new TV, or a mobile refresh rate test on your smartphone, the principle is the same: a higher number means a smoother picture.
Why Does Refresh Rate Matter?
- Smoother Motion: A high refresh rate results in more fluid motion. This is most noticeable in fast-paced games, but it also makes simple actions like scrolling a webpage feel smoother.
- Reduced Motion Blur: With more frames being shown per second, moving objects appear sharper and clearer, which is crucial for a great visual experience.
- Improved Responsiveness: For gamers, a higher refresh rate can lower input lag and make the game feel more responsive to your actions.
Understanding Common Refresh Rates (60Hz vs 120Hz vs 144Hz)
Not all screens are the same. Running a refresh rate test can help you verify that you're getting the performance you paid for. Here's a quick breakdown:
60Hz - The Standard
A 60Hz refresh rate is the long-time standard for most office monitors, laptops, and older TVs. It's perfectly adequate for general use like browsing the web and watching standard videos.
90Hz & 120Hz - The New Mobile & Mid-Tier Standard
Many modern smartphones and mid-range gaming monitors feature a 90Hz or 120Hz refresh rate. A 120Hz refresh rate test will show a noticeably smoother experience over 60Hz, especially when scrolling through social media or playing mobile games.
144Hz & Higher - The Gaming Sweet Spot
For PC gamers, 144Hz is often considered the sweet spot for performance and price. Running a 144Hz refresh rate test and seeing the full value confirms your system is ready for competitive gaming, offering exceptionally smooth and clear motion.
Refresh Rate Test FAQs
Hz (Hertz) is the unit of frequency. For a monitor or any display, it indicates the refresh rate – the number of times the screen updates its image every second. A 60Hz monitor refreshes 60 times per second, while a 144Hz monitor refreshes 144 times per second.
Your monitor is likely set to 60Hz in your display settings. Go to Windows Display Settings > Advanced Display or macOS System Settings > Displays and select 144Hz. Also ensure you're using a DisplayPort cable or HDMI 2.0+ cable, as older HDMI versions don't support high refresh rates.
HDMI 2.0 supports 144Hz at 1080p, while HDMI 2.1 supports 144Hz at 4K. HDMI 1.4 is limited to 60Hz at 1080p. For guaranteed 144Hz support, use DisplayPort 1.2 or newer.
iPhone: Go to Settings > Accessibility > Motion > Limit Frame Rate and turn it OFF. Android: Go to Settings > Display > Screen refresh rate and select 120Hz. Not all phones support high refresh rates - iPhone 13 Pro and newer, and many flagship Android phones from 2020 onward support 120Hz.
G-Sync and FreeSync dynamically adjust your monitor's refresh rate to match your GPU's frame output. During this test, your browser typically runs at the monitor's maximum refresh rate, so you should see your display's peak Hz value regardless of adaptive sync settings.
Yes, this tool functions as an FPS test. It measures the Frames Per Second (FPS) your browser is currently rendering. On most systems, the maximum achievable FPS is limited by the monitor's refresh rate. Therefore, the measured FPS is a very accurate way to check your monitor's Hz.
First, ensure your monitor is set to its highest supported refresh rate in your computer's display settings. Check your cable connection (use DisplayPort for higher rates if available). Update your graphics drivers. Close other demanding applications during the test. If the issue persists, there might be a limitation with your hardware or configuration.
Yes, this mobile refresh rate test works perfectly in any web browser on smartphones and tablets. It's a great way to verify if your phone's screen is running at its advertised 90Hz or 120Hz setting.
