Precision Sensor Calibration • 0 Hz
Move pointer to audit sensor...
When you use your computer, your mouse is your hand's connection to the screen. For most people, a mouse is just a tool to click on things. But if you play games or draw on your computer, you know that not all mice are the same. Some are fast, some are smooth, and some feel like they are dragging behind. That's why we created the Mouse Jitter and Polling Rate tool at Hardware Tester.
Our mission is to help you understand exactly how your mouse is talking to your computer. Whether you have a $10 office mouse or a $150 professional gaming mouse, our tool will reveal the secrets of your hardware sensor with clinical precision.
Imagine you are asking a friend, "Where is your hand?" many times every second. If you ask 125 times a second, that is 125Hz Polling Rate. If you ask 1,000 times a second, that is 1000Hz. The more times the mouse "reports" its position, the smoother it feels on the screen. Gamers love high polling rates because it makes their aim feel instant. Our tool measures your "Peak Hz" to see if your mouse is really as fast as it says on the box!
Have you ever tried to draw a straight line, but the line looks wiggly or shaky? This is called Jitter. It happens when the sensor inside the mouse gets confused by the surface of your desk or if the internal parts are starting to wear out. Our Jitter Score measures these tiny wiggles. A perfect mouse sensor should be smooth and predictable, even when you move it very fast.
Update: Feb 2026 (v4.0.26)
Added support for 8000Hz Hyper-Polling mice. Improved the Jitter algorithm to better filter out human hand shake. New "Event Stream" log allows you to see every single move signal in real-time.
Update: Dec 2025 (v3.5.0)
Introduced "Click Latency" testing. Now you can see how long it takes for your mouse click to reach the computer. Fixed a bug where some Bluetooth mice would show incorrect Hz ratings.
Verify High-End Hardware
Gaming mice often claim 1000Hz or 4000Hz speeds. Use our tool to prove they are actually reaching those speeds. If it's hitting lower, your USB port might be the problem!
Check Your Mouse Pad
A bad mouse pad can cause jitter. Test your mouse on different surfaces (the desk, a book, a pad) and see which one gives the smoothest score.
Find Bluetooth Lag
Wireless mice can sometimes be slow. Check your polling rate while using Bluetooth versus a cable to see how much delay you are actually getting.
Testing your mouse is fun and easy. Just follow these 8-year-old friendly steps:
Expert Tip: If you want the most accurate Polling Rate result, turn off any other apps that are running and move the mouse as fast as you can in a circle for 5 seconds.

Why does my Hz stay at 125?
Most standard office mice and Bluetooth mice are "locked" at 125Hz. This is normal! Only special gaming mice can go higher than that. If you have a gaming mouse, check your mouse software to see if it's set to a higher speed.
What is a "good" Jitter Score?
Lower is always better. If your score is low, it means your mouse is very smooth. If it's high, it means your pointer is jumping around slightly. This can be caused by a dirty sensor or a bad surface.
Can a high polling rate hurt my computer?
Not at all! However, very high polling rates (like 8000Hz) can use slightly more CPU power. Most modern computers handle this just fine.
