Testeur de Clavier
Appuyez sur n'importe quelle touche ou combinaison pour tester l'enregistrement et le ghosting. Toutes les touches actives s'illuminent en temps réel.
Le ghosting de clavier se produit quand certaines combinaisons de touches ne s'enregistrent pas simultanément. Les claviers gaming avec anti-ghosting (N-key rollover) l'évitent.
Qu'est-ce que le Ghosting de Clavier ?
Le ghosting de clavier se produit quand votre clavier ne parvient pas à enregistrer certaines combinaisons de touches parce que son hardware ne peut pas détecter plusieurs appuis simultanés. Cela peut être un problème significatif en gaming où vous appuyez sur WASD + Shift + Espace + clic souris simultanément. Les claviers gaming haut de gamme utilisent la technologie anti-ghosting — N-key rollover (NKRO) — pour enregistrer toutes les touches sans entrées manquées.
Le ghosting est une limitation hardware de la conception de la matrice de touches. Les claviers avec anti-ghosting partiel supportent typiquement le rollover 6 touches. Le N-key rollover complet signifie que chaque touche peut être pressée à la fois. Pour le gaming compétitif, surtout Minecraft PvP, l'anti-ghosting est une caractéristique importante à vérifier.

Questions Fréquentes
Keyboard ghosting occurs when your keyboard fails to register certain keypresses because its controller cannot detect multiple simultaneous inputs. For example, pressing WASD + Shift + Space simultaneously may cause one of those keys to be ghosted (not registered). This is particularly problematic during intense gaming sequences.
N-key rollover means every key on the keyboard can be pressed simultaneously and all will register correctly. This is the gold standard for gaming keyboards. Most quality gaming keyboards today support at least 6-key rollover or full NKRO, ensuring no inputs are missed.
Use our keyboard tester to press combinations you use during gameplay — typically WASD + Shift + Space + additional keys. If any key you press does not highlight in the visualizer, that combination is experiencing ghosting.
For gaming, linear switches (Cherry MX Red, Speed Silver, Gateron Yellow, or equivalents) are most popular due to their smooth, low-actuation-force keypresses. For pure performance, linear switches are preferred. Tactile (Brown) switches are a reasonable middle ground.
Most gaming keyboards operate at 1000Hz polling rate, meaning they report keypress state 1000 times per second — effectively zero input lag from a gaming perspective. Some premium keyboards now offer 8000Hz polling for even lower latency.
This is often a ghosting issue. Minecraft requires many simultaneous keypresses (WASD + Shift + Space + mouse clicks). Budget keyboards may ghost these combinations. Upgrading to a keyboard with 6-key rollover or NKRO resolves this.
Our keyboard tester visualizes key registration and ghosting but does not measure wireless latency directly. Wireless keyboards generally add 1–4ms of latency compared to wired. For competitive gaming, wired keyboards or high-end wireless are recommended.
Use our keyboard tester and press every key one by one. Any key that does not light up when pressed (but adjacent keys do register) is likely stuck, broken, or has a failing switch. Multiple keys failing together indicates ghosting rather than broken switches.
