To check a mouse’s polling rate, open a browser-based polling-rate test, start it when required, and move the mouse continuously across the test area for several seconds. Read the reported rate, average, and any stability or gap indicators. Repeat with the same mouse, connection, profile, browser, and movement pattern when comparing settings.
This is a practical check of the reports that reached that browser session. It is not a direct USB-level measurement, so verify rates above 1,000 Hz with the mouse manufacturer’s utility or an appropriate standalone tool.
What a mouse polling rate measures
Polling rate, also called report rate, is the number of input reports a mouse sends to the computer each second. It is measured in hertz (Hz). A higher setting means reports are scheduled more frequently; a lower setting means a longer interval between reports.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute| Polling rate | Reports per second | Time between reports |
|---|---|---|
| 125 Hz | 125 | 8 ms |
| 250 Hz | 250 | 4 ms |
| 500 Hz | 500 | 2 ms |
| 1,000 Hz | 1,000 | 1 ms |
The interval is calculated by dividing one second by the reports per second. Thus, 1,000 divided by 125 gives 0.008 seconds, or 8 milliseconds; 1,000 divided by 1,000 gives 0.001 seconds, or 1 millisecond. The 125 Hz and 1,000 Hz intervals are documented examples. A Sharkoon SKILLER SGM3 software manual lists 125, 250, 500, and 1,000 Hz as selectable modes, but your mouse may offer different choices.

Polling rate describes reporting frequency, not a guarantee that every report will arrive at the computer at a perfectly even interval. Firmware behavior, the connection, the operating system, and the application receiving the input all affect what you can observe.
Polling rate is not DPI
DPI describes sensor sensitivity: how far the pointer is intended to move for a given physical movement. Polling rate describes how often the device reports its current state. Changing DPI does not automatically change polling rate, and a high-DPI setting does not prove that a mouse is using a high report rate.
Polling rate is not monitor refresh rate
A monitor’s refresh rate is the number of image updates it displays each second. A mouse can report at a different rate from the monitor. Some browser tests deliver or count pointer events in step with display frames, however, so a page’s number can reflect the browser and display-event path rather than the mouse’s raw report cadence.

Before you run the test
Decide what you are trying to verify. If you only want a quick practical answer, an online test is convenient. If you are checking a 2,000 Hz or higher mode, or investigating a disagreement between software and the browser, plan to use the manufacturer’s utility and, where available, a suitable standalone measurement tool as well.
Use the same physical setup for every comparison. A wired connection, a dedicated wireless receiver, and Bluetooth are different input paths. A mouse can also have separate onboard and software profiles, so note the active profile before you begin. If the utility has a battery-saving or performance mode, record that setting too.
How to check polling rate with an online test
The browser method is the quickest way to answer “how to check mouse polling rate” or “mouse Hz test” when you need a practical reading from the computer you are using.
- Connect the mouse. Plug it in directly or connect its wireless receiver as you normally use it. If the mouse has profiles, select the profile whose rate you want to check.
- Open a polling-rate test. Use a reputable browser test page on the computer where the mouse is connected. Avoid changing ports, receivers, or operating-system settings during a comparison.
- Start the measurement. If the page has a Start, Begin, or similar control, activate it. Keep the test tab active so the browser continues receiving pointer events.
- Move continuously. Move the pointer around the designated area for several seconds. Smooth, continuous movement gives the page enough events to calculate a rate; a few short clicks or a stationary pointer do not.
- Record the result. Note the reported rate and, if shown, the average, peak, minimum, gaps, or stability indicator. Treat a single peak as one observation, not as proof of the configured mode.
- Repeat when needed. Run the test again under the same conditions. For a setting comparison, change only the polling-rate setting and repeat the same movement pattern for roughly the same duration.
Conditions that make a browser test more useful
- Use the same browser tab and keep it in the foreground for every run.
- Keep the mouse connected through the same wired port or wireless receiver.
- Use the same mouse profile and disable profile switching during the test.
- Move continuously for several seconds instead of making isolated motions.
- Repeat a reading that looks unusually low or unstable before drawing a conclusion.
- Record the configured rate from the mouse software alongside the browser result.
- Do not switch between Bluetooth and a dedicated receiver halfway through a comparison.
- Keep the test area large enough for uninterrupted movement so you do not repeatedly stop at an edge.
How to read the number you get
A result near the configured setting, repeated across runs, is useful evidence that the browser received reports at approximately that cadence. It does not certify that every USB transaction occurred at exactly that frequency.

Use average and stability, not only the highest number
Many tests display an average, peak, gap count, or stability measure. The average over continuous movement is generally more informative than one momentary maximum. A wide spread between runs, frequent gaps, or a fluctuating graph means the page is not receiving a steady stream of events under those conditions. Repeat the test before changing hardware or concluding that the mouse is defective.
A peak can be above the selected mode because of the way a page samples or groups events; a low moment can likewise reflect delivery timing. Look for a repeatable pattern over several seconds. When comparing 125 Hz with 1,000 Hz, for example, compare the averages and consistency of multiple runs rather than choosing the run with the largest displayed value.
Understand what the browser actually measured
The path is mouse sensor and firmware, then the wired or wireless connection, operating system, browser, and test code. The page measures what survives that path and is delivered to its event handler. Different online tools count events differently, and browser scheduling can delay or combine event delivery. Consequently, two pages can show different values for the same mouse without either value being a direct USB trace.
This distinction matters when a page reports a value that is close to, but not identical to, the setting in the mouse utility. The browser result answers, “What cadence reached this page during this movement?” The utility answers, “What report-rate mode is configured for this profile?” Those are related measurements at different layers.
Why a test can show a lower or fluctuating rate
A lower reading is not, by itself, evidence of a faulty mouse. Logitech’s support guidance warns that third-party and online tests can report a lower rate or fluctuations, especially when processing high report rates. Several ordinary causes can produce that result.
The selected profile is different
Gaming mice often store separate onboard or software profiles. A profile activated by an application, button, or automatic rule may use 125 or 500 Hz even though another profile is set to 1,000 Hz. Open the manufacturer’s software, identify the active profile, and confirm its report-rate setting before testing again.
The wireless device is conserving power
Some wireless mice dynamically vary report rate to extend battery life. During periods of little movement they may report differently from the value seen during continuous movement. Check the manufacturer’s documentation and utility for battery-saving, performance, or wireless-mode settings. Do not diagnose a hardware failure from one fluctuating browser run.

The browser or operating system is dropping timing detail
Background work, a busy tab, display-frame scheduling, or event coalescing can affect when JavaScript receives pointer events. Close unnecessary test tabs, keep the test in the foreground, and repeat. A browser result is particularly limited when the configured rate is high.
The connection or receiver is the variable
A different USB port, hub, extension cable, Bluetooth mode, or wireless receiver position changes the input path. For a controlled comparison, use the same connection method and receiver placement for every run. If a wireless mouse supports both Bluetooth and a dedicated receiver, test each mode separately rather than treating them as equivalent.
The movement was too brief
A test cannot estimate a steady cadence from a few clicks or a short twitch. Keep moving for several seconds, then repeat the run. If the page reports a minimum, average, or gap count, record those values rather than relying on the first number that appears.
Checking the configured rate in mouse software
The most authoritative place to see the setting is the mouse manufacturer’s companion application. Open the device page and look for a control named Polling rate, Report rate, or a similar term. Select the intended value, apply or save the profile, and then run the browser test again.
- Launch the mouse’s companion software.
- Select the connected mouse, not a keyboard or another peripheral.
- Open the performance, sensor, wireless, or device-settings panel.
- Find Polling rate or Report rate.
- Check which profile is active and note whether the setting is stored on the mouse or only in software.
- Choose the desired rate, apply the change, and wait for the device to reconnect if the utility requests it.
- Return to the browser test and repeat the continuous-movement procedure.
Exact labels and available values vary by model. Some mice also provide a hardware button or switch that cycles through rates. If software and hardware controls both exist, verify which one has priority and which profile is currently active. A displayed setting is not necessarily active if the utility has not applied or saved the profile.
How to compare two polling-rate settings fairly
If you are deciding whether a setting change is actually reaching the computer, use a fixed procedure rather than comparing unrelated readings.
- Write down the starting rate shown in the mouse utility.
- Use one computer, browser, test page, connection method, and mouse profile.
- Run several seconds of continuous movement and record the average and stability information.
- Change only the polling-rate value.
- Allow the mouse or receiver to reconnect if prompted.
- Repeat the same movement pattern for the same approximate duration.
- Run at least one additional repetition if the values differ substantially between runs.
Compare the pattern of averages and consistency, not just the largest number from either run. If the configured setting changes but the browser readings overlap or fluctuate, that may reflect the browser measurement layer rather than a failure to apply the setting.

What to do with rates above 1,000 Hz
For rates higher than 1,000 Hz, treat an online result as indicative only. Logitech specifically cautions that browser-based tools may not process its mice’s high report rates correctly and advises against relying completely on third-party tests.
First confirm the selected high-rate mode in the manufacturer’s utility. Then use a suitable standalone measurement tool that observes input at a lower level than a web page, if one is available for your operating system and device. Keep the same profile and connection while comparing tools. A browser page that reports a lower or unstable value cannot, by itself, establish that the mouse is failing to deliver the configured high rate.
Troubleshooting by symptom
The page shows no rate
- Click the page’s Start control if one is present.
- Move the pointer inside the test area rather than outside the page.
- Confirm that the browser tab is active and that the operating system sees the mouse.
- Reload the page and repeat with the mouse connected directly.
The result is much lower than the setting
- Verify the active hardware or software profile.
- Check whether the mouse is in a battery-saving or lower-performance wireless mode.
- Repeat continuous movement for several seconds.
- Try the manufacturer utility and, for high rates, a suitable standalone tool.
The result changes from run to run
- Keep the same browser and foreground tab.
- Use the same port, receiver, and connection mode.
- Close unnecessary browser activity.
- Compare averages and stability indicators rather than isolated peaks.
- Repeat before replacing the mouse or declaring a defect.
The browser and manufacturer utility disagree
The utility reports the configured mode; the browser reports events delivered to its page. Confirm the profile and connection first. If the setting is high, give greater weight to a suitable standalone measurement than to a browser page that may be limited by event timing.
When changing polling rate is worth investigating
Checking the rate is useful when a game, application, or troubleshooting guide asks for a specific report-rate setting, when you are comparing wired and wireless modes, or when a mouse utility appears not to save a profile. It is also useful for confirming that a hardware switch actually changed the selected mode.
The test should answer a narrow question: what input cadence reached this computer under these conditions? It should not be used as a standalone diagnosis of sensor quality, pointer precision, or monitor performance. Those are separate characteristics.

Why does my mouse show a lower report rate than its setting?
An online test measures events delivered to that browser, not a direct USB trace. Browser scheduling, event counting, the active profile, wireless power management, and the connection can all produce a lower or fluctuating result. Logitech warns that third-party and online readings can be unreliable, especially at high rates.
Is polling rate the same as DPI?
No. DPI concerns sensor sensitivity and pointer movement. Polling rate concerns how often the mouse reports its state. Changing one does not automatically change the other.
Is polling rate the same as monitor refresh rate?
No. Monitor refresh rate describes image updates. Mouse polling rate describes input reports. A browser test can still be influenced by display-frame and browser event timing.
Recommended Free Tools
Should I trust a browser test above 1,000 Hz?
Treat it as indicative rather than conclusive. Confirm the configured mode in the manufacturer’s utility and, when available, use a suitable standalone measurement tool. Logitech says browser tools may not process high report rates correctly.
How long should I move the mouse during a polling-rate test?
Move continuously for several seconds. Short clicks, a stationary pointer, or a few brief motions do not provide enough events for a useful estimate.
Why do two polling-rate websites show different numbers?
Online tools can receive and count pointer events differently, and browser scheduling can delay or combine delivery. They may therefore report different values from the same mouse without either being a direct USB-level measurement.
Where can I change the polling rate?
Open the mouse manufacturer’s companion software and look in the performance, sensor, wireless, or device-settings panel for Polling rate or Report rate. Some models also have a hardware button or switch, and exact options depend on the model.

For a practical mouse Hz check, use an active browser test, move continuously for several seconds, and compare repeated averages rather than one peak. Keep the profile, browser, connection, and movement consistent. Verify the configured value in the manufacturer’s software, and cross-check any rate above 1,000 Hz with the maker’s utility or a suitable standalone tool. A low or fluctuating browser result alone does not prove that the mouse is defective.
