Settings to record before comparing
Write down mouse acceleration and pointer speed, keyboard repeat delay and rate, remapping tools, controller calibration, game deadzones and connection mode.
Write down mouse acceleration and pointer speed, keyboard repeat delay and rate, remapping tools, controller calibration, game deadzones and connection mode. These can change observable behavior without a hardware change. Save trial A, modify one intended setting and repeat the same procedure for trial B. Do not use our exploratory thresholds as manufacturer tolerances. eDPI compares DPI multiplied by sensitivity only within the same game scale. The DPI estimator uses CSS displacement and is not sensor calibration. If your result raises a concern, reproduce it outside this website and consult the device maker before deciding on repair or replacement.
Measurement limits
A browser observes events exposed by your operating system. One test cannot establish whether a device is faulty. Connection, settings, focus and browser behavior can change the results.
