CPI Mouse Test
Check CPI, DPI, pointer speed, and profile problems before buying another mouse.
Check path
Switch DPI or CPI steps and watch whether cursor distance changes predictably.
Reset mouse software profiles, onboard memory, and OS pointer speed if steps feel wrong.
Compare another browser or machine before treating sensitivity as hardware failure.
Buy later
Fix profiles when one DPI or CPI step is mapped incorrectly.
Fix pointer speed or acceleration when all profiles feel equally wrong.
Compare gaming mouse options only when DPI changes stay inconsistent across reset software and machines.
Repair picks
When click latency, polling consistency, or DPI steps stay bad after software and connection checks, compare wired or low-latency wireless mice.

FAQs
Can I test exact mouse DPI in the browser? +
A browser cannot read the hardware DPI value directly. It can help you compare whether sensitivity changes consistently across CPI steps, DPI profiles, pointer speed, and acceleration settings.
Why does my mouse DPI feel wrong? +
Profile software, onboard memory, OS pointer speed, acceleration, and game settings can all change sensitivity. Reset profiles and pointer settings before blaming hardware.
Should I replace a mouse for DPI problems? +
Only when DPI/CPI steps behave inconsistently across reset profiles, clean pointer settings, and another machine. If settings explain the change, buying another mouse is premature.
