Monitor Refresh Rate (Hz) & Mouse Polling Rate Diagnostic

Verify your monitor's real-time refresh rate (60Hz, 144Hz, 240Hz, 360Hz) and measure mouse sensor polling rates (1000Hz+) with sub-millisecond precision. Competitive gamers and display enthusiasts use this utility to diagnose frame skips, verify GPU display settings, and test gaming mouse sensor responsiveness.

How It Works Client-Side

Using high-precision browser animation loops (requestAnimationFrame) and event timestamp tracking, the tool measures display frame intervals and USB input frequency directly through browser hardware APIs.

Step-by-Step Instructions

  1. Open the test window and allow the frame counter to calibrate.
  2. Verify that your detected display Hz matches your physical monitor specs.
  3. Move your mouse continuously inside the motion box to record peak polling frequency.
  4. Review diagnostic stability charts for frame drops or input lag spikes.

❓ Frequently Asked Questions

Why does my 144Hz monitor only display 60Hz in the test?

Ensure your display settings in Windows/macOS and GPU control panel are manually set to 144Hz.

How do I accurately test mouse polling rate?

Move your mouse rapidly in continuous circles inside the designated test region.

Does browser hardware acceleration affect results?

Yes. Keep hardware acceleration enabled in browser settings for accurate frame delivery.

Is this tool accurate for competitive esports setups?

Yes, it uses sub-millisecond DOM High Resolution Timestamps (performance.now()).
