Professional Keyboard Test Tool Features
📖 Introduction: This professional keyboard test tool provides comprehensive keyboard detection functionality, from basic key functionality to advanced performance analysis, helping you fully understand your keyboard's condition. Supports all keyboard types including mechanical, gaming, laptop, and more.
🔍 Full Key Layout Detection
Test each key on your keyboard individually to ensure all keys respond properly. Tested keys will highlight in green and track keystroke counts.
Tip: Test all keys sequentially to ensure none are missed.
⚡ NKRO Anti-Ghosting Test
Test your keyboard's N-key rollover (anti-ghosting) capability. Press multiple keys simultaneously and observe the "Active Keys" counter to understand your keyboard's conflict prevention performance.
⏱️ Response Speed Analysis
Real-time display of key press intervals helps you evaluate keyboard response latency and input smoothness. Identify key sticking or sluggish response issues.
Monitor Time Delta values - lower means faster response
🔧 Technical Parameter Display
Display underlying technical parameters like event.key, event.code, event.which for developers and advanced users to perform deep analysis and troubleshooting.
Technical parameters help identify specific key codes
🎯 Optimized Testing Workflow
Provides standardized testing workflow: basic test → anti-ghosting test → rapid tapping → combination key testing to ensure comprehensive coverage of all test scenarios.
Follow recommended workflow for best results
📊 Data Statistics Functionality
Real-time statistics on tested keys, total keystrokes, and concurrent key presses to quantitatively assess keyboard performance and testing progress.
Statistics help systematically evaluate keyboard condition
Frequently Asked Questions (FAQ)
Why aren't some keys being detected?
This may be due to browser security restrictions or keyboard hardware issues. Please ensure: 1) Using modern browsers (Chrome/Firefox/Edge); 2) Focus is on the testing page; 3) Check keyboard connection.
What is N-key rollover (NKRO)?
N-key rollover means a keyboard can recognize an unlimited number of simultaneous key presses without conflicts. Standard keyboards typically support 6-key rollover, while professional gaming keyboards offer full N-key rollover.
How to identify keyboard issues?
If certain keys: 1) Show no response at all; 2) Have noticeable response delays; 3) Exhibit key chattering; 4) Conflict with other keys, it may indicate keyboard hardware issues.
What keyboard types are supported?
All keyboard types: mechanical keyboards, membrane keyboards, capacitive keyboards, laptop keyboards, etc. Compatible with Windows, macOS, Linux systems.
How to test keyboard latency?
Rapidly tap the same key repeatedly and observe the Time Delta value. Professional gaming keyboards typically have 1-5ms latency, while standard keyboards may reach 10-20ms.
Is test data saved?
All test data is only saved in your current browser session. Data will be lost when refreshing the page or closing the tab. Use screenshot functionality if you need to save results.
