N-Key Rollover and Anti-Ghosting: What Buyers Should Know
These two related but distinct terms get used inconsistently in keyboard marketing — here’s the actual technical difference.
Published 2026-03-26 · Computer Peripherals
Anti-Ghosting
Prevents specific key combinations from registering incorrectly (a common issue when multiple keys are pressed simultaneously on lower-cost keyboard matrices), typically covering a defined set of common gaming key combinations.
N-Key Rollover (NKRO)
Goes further, guaranteeing every key can register correctly regardless of how many others are held down simultaneously — the more complete and more expensive-to-implement solution, standard on competitive-tier gaming keyboards.
