NKRO Test

Number of simultaneously pressed keys:
  • Current: 0
  • Maximum: 0

What is NKRO?

NKRO (N-Key Rollover) is a technology that allows the keyboard to process all simultaneously pressed keys without any limitations. The “N” symbol represents any number: the system is guaranteed to register every keypress, even if you press every key on the device at once.

How to test NKRO?

  1. Press several keys simultaneously.
  2. Check the display of all pressed keys.
  3. Continue pressing more keys to find the maximum number.

Rollover Types

  • Without NKRO (2-Key Rollover): only 2 keys are registered at a time.
  • 6-Key Rollover (6-Key Rollover): only 6 keys are registered at a time.
  • NKRO (N-Key Rollover): all pressed keys are registered simultaneously.

Why is NKRO important?

  • Gaming—ensures instant registration of all commands.
  • Speed Dial—prevents missed keystrokes.
  • Multimedia Tasks—allows you to use complex simultaneous key combinations.
