Full N-key rollover

Full N-key Rollover with 100% Anti-Ghosting
Capture Every Simultaneous Key Press

The Das Keyboard 4Q with full n-key rollover (NKRO) has the ability to scan each button press individually, as opposed to having the PC do it. As a result, every pressed key is noted, even if you are pressing a bunch of keys simultaneously. This is particularly relevant to gaming because it gives gamers unlimited simultaneous use of all the keys during gameplay. With n-key rollover, it is possible to press as many keys as needed to enhance one’s gaming performance. N-key rollover technology also combats the issue of ghosting (an extra letter or key is erroneously registered) because each key is scanned independently. The 4Q will always read all keystrokes, optimizing your gameplay and typing.
