KeyboardTest is a diagnostic program for Windows designed to test and verify the functionality of desktop and laptop keyboards. It is possible to detect stuck, faulty or incorrectly mapped keys.
Issues
The dashboard visually displays each key press in real time on a clear graphical keyboard layout. As each button is pressed, it is highlighted on-screen, making it easy to confirm its functionality and mapping. Users can see whether items are stuck, unresponsive or triggering incorrect values.
The app supports N-key rollover testing, allowing you to press multiple keys simultaneously and verify proper recognition. You may identify ghosting issues or hardware limitations in gaming keyboards or professional input devices. Additionally, you can try Logi Options to maintain your Logitech mice.
Reaction
There are performance diagnostics to evaluate key switch response time and repeat rate behavior. The metrics are useful in assessing mechanical or membrane keyboards’ responsiveness and detecting wear over time. In case you sip your coffee on your device or damage the laptop, you are able to see which buttons react slower to your movements.
Please note that the tools are also suitable for testing LED indicators. You can check your Num, Caps and Scroll locks, generating detailed analysis.
