What is DPI?
DPI is the common consumer term for the mouse sensor's counts-per-inch setting. Higher DPI generally means more reported counts for the same physical movement.
Can a website read my mouse DPI directly?
No. A normal web page does not receive the mouse sensor's internal DPI register. A browser tool can estimate the relationship between physical movement and pointer movement.
What is the most accurate way to know my DPI?
Use the manufacturer's configuration utility or the profile stored by the mouse. A browser analyzer is useful as an independent practical check.
Why is my measured DPI different?
Possible causes include acceleration, scaling, physical-distance error, pointer-event behavior, hand movement, or lifting the mouse. Repeat the test under controlled conditions.
Is 800 DPI better than 1600 DPI?
Neither is universally better. The appropriate choice depends on the complete setup and personal control. Compare the resulting sensitivity using eDPI or cm/360.
What is polling rate?
Polling rate is the frequency at which a mouse reports input to the computer. It is separate from DPI. A higher polling rate does not mean a higher DPI.
What is eDPI?
eDPI is commonly calculated as mouse DPI multiplied by in-game sensitivity. It is useful for comparing settings within the same game.
Does the analyzer upload my measurements?
The analyzer is designed to perform measurement and calculation locally in your browser. It does not need to upload your pointer measurements to a server.
