Frequently Asked Questions

Encuentre respuestas rápidas

What is keyboard ghosting?

Keyboard ghosting occurs when pressing multiple keys simultaneously causes some key presses to not register. This happens due to electrical limitations in the keyboard's matrix design.

What is key rollover (NKRO)?

Key rollover refers to how many simultaneous key presses a keyboard can register. NKRO (N-Key Rollover) means all keys can be pressed simultaneously and still register correctly.

Why is ghosting important for gaming?

In games, players often need to press multiple keys at once (like moving while jumping and shooting). Ghosting can cause actions to not register, affecting gameplay performance.

How accurate is this ghosting test?

The test accurately detects which key combinations your keyboard can and cannot register simultaneously by monitoring all keyboard events in real-time through the browser's keyboard API.
