Comprehensive Hardware Testing Suite
ValidDeck provides a comprehensive suite of professional-grade hardware testing tools organized into three main categories: Input devices, Output devices, and Capture devices. Our tools help you diagnose and verify the functionality of your computer peripherals with accurate, real-time diagnostics without the need for complex software installations.
Input Device Testing
Our input device testing tools cover keyboards, mice, and gamepads. The keyboard tester identifies key ghosting, mechanical switch problems, and rollover limitations. The mouse tester detects double-click issues, verifies all button functionality, and tests scroll wheel performance. The gamepad tester checks controller buttons, analog stick precision, and detects stick drift—a common issue affecting modern controllers.
Output Device Testing
Our output device testing tools help you verify display and audio quality. The screen tester (dead pixel test) identifies dead pixels, stuck pixels, color uniformity issues, and backlight bleeding. The refresh rate tester measures your monitor's Hz in real-time using requestAnimationFrame. The audio tester verifies stereo channel separation, tests frequency response from 20 Hz to 20 kHz, and helps identify audio quality issues in headphones and speakers.
All our tools are designed with both casual users and professionals in mind. Whether you're troubleshooting hardware issues, testing new purchases, or performing routine maintenance, ValidDeck provides the diagnostic capabilities you need to keep your hardware in optimal condition.
When to Use Hardware Testing Tools
Hardware testing tools are essential in various scenarios. If you're experiencing unexpected behavior from your keyboard or mouse, such as keys not responding, double-clicks, or ghosting issues, our tools can help pinpoint the exact problem. This is particularly useful before investing in repairs or replacements, as it helps you determine whether the issue is hardware-related or software-related.
When purchasing a new keyboard or mouse, testing tools can verify that all features work as expected right out of the box. This is especially important for gaming peripherals, where precise input and reliability are critical. Regular testing can also help identify wear and tear before it becomes a significant problem, allowing you to maintain your devices proactively.
After cleaning your devices, testing tools ensure that all components are functioning correctly. This is important because cleaning can sometimes dislodge components or leave residue that affects performance. By testing after maintenance, you can confirm that your cleaning efforts were successful and that no new issues were introduced.
Understanding Hardware Specifications
Modern computer peripherals come with various specifications that affect their performance. For keyboards, key rollover (KRO) is a critical specification that determines how many keys can be detected simultaneously. Standard keyboards typically support 6-key rollover, while gaming keyboards often feature full N-key rollover (NKRO) for unlimited simultaneous key detection. Our keyboard tester helps you verify your keyboard's actual rollover capabilities.
For mice, polling rate is an important specification measured in Hertz (Hz), indicating how often the mouse reports its position to the computer. Higher polling rates result in lower input latency and smoother cursor movement, which is crucial for gaming and precision tasks. While our mouse tester doesn't directly measure polling rate, it helps ensure that all buttons and functions are working correctly, which is essential for optimal mouse performance.
Understanding these specifications and using testing tools to verify your hardware's performance helps you make informed decisions about your peripherals. Whether you're a casual user, a professional, or a competitive gamer, having reliable, well-functioning hardware is essential for productivity and enjoyment.
