Should I replace my keyboard for ghosting?
Answer when keyboard ghosting justifies replacing a keyboard, when USB or remaps are enough, and how NKRO fits real combo failures.
Short answer
Not for every ghosting result. Replace only when the key combinations you actually use fail in the tester, the same combos fail over USB, and remaps or game settings cannot avoid the blocked matrix.
Confirm first
Test the exact combo that fails.
Retest over USB or another port.
Move to NKRO only for real blocked combos.
Why this matters
HWProbe keeps the answer tied to evidence: run the matching browser test, try the reversible fix, then replace only when the same fault repeats. Tests run locally in your browser at hwprobe.com.

Frequently Asked Questions
Do I need NKRO for gaming? +
You need NKRO only if your real inputs fail. Many games work fine on 6KRO boards, but rhythm games, flight controls, and complex shortcuts can expose matrix limits.
Can remapping avoid keyboard ghosting? +
Often yes. If moving one action to a different key avoids the blocked matrix, replacement may be unnecessary. Replace when the required combo cannot be changed cleanly.
