FAQ
Do I need to install anything for this guide?
No. The recommended checks run in a modern browser unless the article specifically points you to an operating-system or device setting.
Is the browser test private?
The KeyboardTester.click tools are designed to run the test interaction in your browser. Do not type passwords, private messages, or sensitive account data into any testing page.
What should I do if the result looks wrong?
Repeat the test in a clean browser tab, then change one variable at a time such as device, cable, USB port, permission, wireless mode, or browser profile.
When should I use a related tool?
Use a related tool when the first result points to a narrower issue, such as latency, ghosting, stuck input, camera permission, audio routing, or QR/OCR decoding quality.
