Refresh Rate Test
Check your actual monitor Hz (60Hz, 120Hz, 144Hz, etc).
Current Refresh Rate Detected
Please allow a few seconds for the reading to stabilize. This detects the rate at which your browser is painting frames.
What is refresh rate test?
A refresh rate test measures how many frames per second (FPS) your monitor is currently displaying. The refresh rate, measured in Hertz (Hz), determines how smooth motion appears on your screen. Common values are 60Hz for standard screens and 144Hz or higher for gaming monitors.
This tool uses your browser's specialized animation API to count the exact rate at which the browser is painting frames. This confirms if your operating system and cable settings are correctly configured to deliver the maximum smoothness your monitor supports. If you bought a 144Hz monitor but this tool shows 60Hz, you likely need to adjust your Windows/Mac display settings.
How to use refresh rate test
- Step 1: Close other tabs and heavy applications for the most accurate result.
- Step 2: Allow the tool to run for a few seconds to stabilize.
- Step 3: Read the large number displayed (e.g., 60 Hz, 144 Hz).
- Step 4: If the number is lower than expected, check your OS Display Settings and ensure you are using a high-bandwidth cable (DisplayPort or HDMI 2.0+).
Frequently Asked Questions
Why is my 144Hz monitor showing 60Hz?
This is very common. You likely haven't enabled the high refresh rate in Windows Settings > System > Display > Advanced Display Settings.
Does browser performance affect this?
Yes, if your browser or computer is lagging, the detected FPS might drop below the actual monitor refresh rate.
