Keyboard Ghost Key Test
Detect keyboard Ghost Key and NKRO capabilities, test conflicts when multiple keys are pressed simultaneously, evaluate keyboard gaming and professional application performance
• Ghost Key: The phenomenon where certain keys cannot be properly recognized when multiple keys are pressed simultaneously
• NKRO (N-Key Rollover): The maximum number of keys that a keyboard can simultaneously recognize
• Gaming Impact: Anti-ghosting performance directly affects multi-key operation experience in games
• Mechanical Keyboards: Usually have better anti-ghosting performance than membrane keyboards
• Test Significance: Helps you understand keyboard reliability in high-intensity usage scenarios
⚠️ Hardware Limitations
• USB HID Protocol: Standard USB keyboards support maximum 6 simultaneous regular keys
• Keyboard Hardware: Regular keyboards support 6KRO, high-end gaming keyboards may support 10-key or full NKRO
• Browser Environment: May have additional limitations on simultaneous key detection
• Test Design: Our test combinations are optimized for maximum 6 keys to accommodate most keyboard hardware
