Mouse polling rate and monitor refresh rate both use hertz (Hz), but they count different things. Polling rate is how often your computer asks the mouse for a fresh update. Refresh rate is how often the display can show a new frame.
That is the core meaning of mouse polling rate when you see it next to a monitor spec. The two numbers describe separate steps between your hand and the image on screen, so they do not need to match. A mouse listed at 1000 Hz paired with a 144-Hz monitor, for example, is not a mismatch you need to fix.
What Mouse Polling Rate and Monitor Refresh Rate Measure
Each Hz figure tells you how many times per second one specific event happens: a request for mouse data, or a chance for the monitor to show a new frame.
Mouse Polling Rate: How Often the Computer Requests an Update
The polling figure on a mouse spec sheet refers to USB polling. It describes how often the computer asks the mouse to update, meaning how often the PC requests a new report from the mouse. Each request is a check-in where the mouse can pass along movement or clicks. A bigger number means more check-ins per second.
This number is not the sensor's own sampling rate. The sensor is the optical part on the underside of the mouse that tracks your desk or pad. It works on its own internal schedule, separate from the USB polling link. So the practical meaning of mouse polling rate is narrow: it is the reporting cadence between the mouse and the computer, not a measure of how the sensor reads the surface.
If you want to know what changing that cadence does in practice, our guide to polling rate and latency compares 1K, 4K, and 8K intervals and how they affect CPU workload.
Monitor Refresh Rate: How Often the Display Updates
Refresh rate lives on the display side of your setup. It describes how often the monitor updates the image you see. The monitor shows frames that the graphics card sends to it, and the refresh rate sets how many chances it gets each second.
The cited 60-Hz LCD example makes this concrete. A 60-Hz LCD can display up to 60 discrete frames every second, with a gap of about 16.66 ms between frames. Think of those as frame opportunities: moments when the screen can change what it shows.
Note the words "up to." The refresh rate is the display's limit for new frames. It does not promise that a new frame arrives at every refresh. The 16.66 ms figure also belongs to this 60-Hz LCD example only. It is the spacing between refreshes, not the full time from a mouse movement to a change on screen.
How the Two Rates Relate
Because USB polling requests and monitor frame updates count different events, the two values do not need to match one-to-one.
It helps to picture the path from input to image as a chain. Near the start, you move the mouse and the computer polls it for that movement. Near the end, the monitor shows a frame at one of its refresh opportunities. Other steps sit in between, such as the game handling your input and the graphics card producing a frame. Neither Hz number describes those middle steps.
Because polling and refresh sit at different points in that chain, a shared unit does not make them a pair. Hz simply means "times per second." One figure counts requests to a mouse. The other counts chances for a screen to update. Comparing them directly is a bit like comparing how often a store restocks shelves with how often its doors open. Both happen per hour, but they measure different jobs.
This also sets a limit on what each spec can tell you. Neither figure alone gives you the total delay from input to image, and neither predicts how responsive a game will feel. Use each one to answer its own question: how often the PC hears from the mouse, and how often the screen can change.
When you compare models in our wireless gaming mouse lineup, read the polling figure as the mouse-to-PC reporting cadence. Your monitor's refresh rating is a separate spec that describes a separate device.
FAQs
Is the 16.66 ms gap on a 60-Hz screen the same as input lag?
No. In the same monitor guide, input lag is defined as the delay between the graphics card sending a frame and the monitor displaying it. The 16.66 ms figure is the spacing between refresh opportunities on a 60-Hz LCD. They are two different display measurements, and a spec sheet may list one without the other.
Does my monitor's refresh rate control how often my mouse is polled?
No. Polling is a request schedule between the computer and the mouse over USB, while refresh rate is a property of the display. Some players still consider their CPU and monitor when picking a polling setting for a specific game. Our Valorant polling rate guide walks through that choice between 1000 Hz, 4000 Hz, and 8000 Hz.
Can I check which polling rate my mouse is actually using?
Yes. You can run our mouse polling rate test tool to check rates such as 1000 Hz, 4000 Hz, or 8000 Hz. Compare the reading with the setting you chose in your mouse software. If they differ, recheck that setting before testing again.
Does a higher polling rate number tell me my total latency?
No. Polling describes only the mouse-to-computer step, so a spec sheet number cannot show the full delay to the screen. Measuring latency takes testing the whole setup. Our 8000Hz vs. 1000Hz latency tests look at measured motion latency and jitter across six gaming mice.
