Quick answer
What this guide helps you determine
Understand USB report rate, browser pointer events and why an online estimate is not a firmware measurement.
Begin with the observable browser result, repeat it under the same conditions, and change one connection, setting or application at a time. A browser result narrows likely causes but does not certify hardware or decide a repair.
Scope of this check
Mouse polling rate is the frequency at which a connection reports data, commonly described in hertz. A web page sees pointer events after USB or wireless transport, the operating system, browser coalescing and main-thread scheduling, so an online value is an event-frequency estimate rather than a direct firmware reading.
Step-by-step method
- Move the mouse continuously in smooth circles for several seconds inside the test surface. Avoid short flicks that provide too few intervals. Keep the tab visible and close heavy pages or applications that can block the browser main thread.
- Repeat several samples and compare the median or stable range rather than the single highest number. Keep display refresh, connection mode, browser and power settings unchanged between comparisons.
- If the vendor utility exposes a polling setting, change one value, reconnect if required and run the same motion again. A consistent relative change is meaningful even when the browser estimate is below the configured hardware rate.
What to check first
Use these checkpoints to keep the comparison focused. Record the visible behavior rather than assigning a fault label too early.
- Use continuous movement
- Compare repeated median values
- Keep browser load and display settings constant

How to read what you see
| Observation | What it can suggest | Useful next check |
|---|---|---|
| Repeated estimates cluster near one range | The browser is receiving events at a reasonably stable rate under these conditions. | Use the range as comparative browser evidence. |
| The estimate drops while the page stutters | System load or browser scheduling may be limiting observation. | Close heavy tasks and repeat with the tab foregrounded. |
| Wired and wireless modes differ consistently | Connection mode, power saving or receiver conditions may affect delivery. | Check battery, receiver placement and supported device settings. |
Common mistakes to avoid
- Do not report the browser estimate as certified USB report rate.
- Do not compare different motion speed or sample duration.
- Do not chase a peak number while ignoring stability and actual use.
Build evidence another person can use
Write down the exact action, visible result and whether it repeats. Include the browser family, operating-system family, connection type and the single comparison that changed the result. Quote the observation directly—for example, “Repeated estimates cluster near one range”—then add where it occurred and which comparison changed it.
Change one condition per comparison and return settings that have no effect. Follow model-specific manufacturer instructions before firmware changes, cleaning, disassembly or warranty action.
When to seek qualified support
If the same problem remains in multiple applications and on another compatible connection or computer, collect the repeatable observations and contact the manufacturer or a qualified technician. Stop using equipment that is physically damaged, unusually hot, wet, sparking or unsafe. Device Test Bench cannot inspect electrical condition or make a repair decision.
Privacy during testing
Our public tests process key events, pointer values, media streams and controller input locally. Do not send private recordings, complete typed text or device identifiers when asking for help. A short description of the behavior, browser and page URL is normally enough.
Questions readers ask
Why is a 1000 Hz mouse shown below 1000 Hz?
The browser may coalesce events, the display and main thread schedule work differently, and the sample includes more than the USB link.
Does a higher number always feel better?
Not necessarily. Stability, system load, game processing, display latency and personal use all matter.
