FAQs
How do I test Logitech keyboard ghosting? +
Open the ghosting test and press the exact key combination that fails in your game or app. A useful test is combo-specific, not just pressing random keys.
Does Logitech keyboard ghosting mean the keyboard is broken? +
Not always. Some keyboards have matrix limits by design. If only one impossible combo fails, remapping may be better than replacing the board.
Should I buy an NKRO keyboard for gaming? +
Buy one only when the combos you actually use fail repeatedly and remapping does not solve it. Wired NKRO boards are the cleanest upgrade path for combo-heavy games.
Repair path
