Frequently Asked Questions
What is N-key rollover?
N-key rollover means the keyboard can detect all keys pressed simultaneously without ghosting.
What is keyboard ghosting?
Ghosting occurs when a keyboard fails to register certain key combinations due to hardware limitations.
How is response time measured?
Response time is the duration between keydown and keyup events, averaged across all tested keys.
