About GearCheck

GearCheck is a set of small tests for a mouse that double clicks, a key that does nothing, a drifting controller, a stuck pixel or a quiet microphone.

Each test shows what your browser receives from the device. Nothing is uploaded and there are no accounts. Drivers and the operating system can filter input, so treat a result as a clue to follow up, not a repair diagnosis.

Ads

The site may show labelled Google ads. They don’t affect results, and no troubleshooting advice is paid for. See the privacy policy.
