How to Test Mechanical Keyboards & Ghosting

Keyboard ghosting happens when certain key combinations fail to register simultaneously due to hardware matrix limits. You can test your keyboard using our visual layout:

• Key Chatter & Double Typing: Press individual keys to ensure they register cleanly without registering unintended duplicate keystrokes.
• Key Matrix & N-Key Rollover (NKRO): Hold down multiple keys at once (e.g., WASD + Spacebar + Shift) to confirm all inputs register without ghosting.

How to Detect Mouse Double-Clicking Bugs

Mechanical mouse micro-switches often develop contact wear over time, causing a single press to trigger two rapid clicks (chatter bug). Use our **Mouse Test Pad** to click naturally—if two clicks occur within less than 80 milliseconds, our tool flags a potential double-click defect.
