- What is NKRO and do I need it for gaming?
- N-key rollover means the keyboard can report every key at once, with no upper limit. For most shooters and MOBAs six keys is plenty, because you rarely hold more than four. It matters for rhythm games, fighting game macros and anyone who hammers six keys plus a movement combo.
- Why does my wireless gaming keyboard stop at six?
- Many boards fall back to the basic USB boot protocol in wireless or Bluetooth mode for compatibility with consoles and BIOS screens, and that protocol carries six keys. The same keyboard over its cable may go well beyond six. Check for a mode switch or an NKRO toggle in its software.
- Is ghosting the same as a dropped input?
- Ghosting in the strict sense is a phantom key that shows up although you never pressed it. Modern firmware blocks those, so what you actually see today is the opposite: a real key that the board refuses to report because it cannot separate it from the others you are holding. Both come from keys sharing matrix lines.
- Some keys work alone but vanish when I hold WASD. Why?
- That is the matrix problem in action. Keys in the same electrical row or column as W, A, S or D can become ambiguous once three corners of a rectangle are held, and the controller drops the fourth. Rebinding the problem key somewhere else on the board is the quick fix.
- Can the browser or Windows block keys in this test?
- A few. Windows keeps combinations like Win+L and Alt+Tab for itself, and the Fn layer never leaves the keyboard at all. Everything else that appears here would also reach a game, so a key that is missing here would be missing in a match too.
