Keyboard key rollover refers to the number of keys you can press simultaneously on a keyboard and still register correctly.

Key rollover is important because it determines how many keys can be pressed at once without ghosting or blocking.

Ghosting is when one key press is not registered because another key press is blocking it. For example, if a keyboard has a 2-key rollover, it can only register 2 keys pressed at once. If a user presses more than 2 keys at once, some key presses may need to be registered.

A higher key rollover lets you press more keys simultaneously without ghosting, making it more suitable for gaming and typing at high speeds.


What is ghosting in Keyboards?

Ghosting in keyboards is a common issue caused by the keyboard’s internal hardware limitation, where multiple key presses overload the circuit board and don’t register properly. But don’t worry; you can mitigate it using a keyboard with a higher key rollover or a better-quality circuit board.

What is blocking in Keyboards?

Blocking in keyboards is when multiple key presses don’t register correctly, resulting in missed keystrokes. It’s like a traffic jam inside your keyboard! You can avoid it using a keyboard with higher key rollover and a better quality circuit board.

What is NKRO and its ideal number?

NKRO (N-Key Rollover) is a feature that lets you press as many keys simultaneously as you want without any missed keystrokes. The higher the NKRO, the more keys you can press simultaneously. The optimum NKRO is the highest possible number that the keyboard can handle. It’s like having a super keyboard that can address all your typing needs!
