Understanding Ghosting

What is Ghosting?

When you press certain keys simultaneously and your keyboard fails to register one or more of them. Common in cheap membrane keyboards.

Key Rollover (KRO)

The number of simultaneous keys a keyboard can handle. Gamers target N-Key Rollover (NKRO), meaning every single key can be pressed at once.

Gaming Pro-Tip

"Most modern mechanical keyboards support at least 6KRO. If you see your 'Peak Rollover' stuck at 3 or 4, your hardware might be limiting your input speed in high-APM games."
