Works With Your Device, Your OS, Your Brand

Test My Devices runs on Windows 10, Windows 11, and macOS without requiring any platform-specific software, drivers, or extensions. Whether you're on a MacBook Pro testing a wired keyboard or on a Windows desktop diagnosing a wireless gaming mouse, the browser handles hardware communication directly through standard Web APIs.

How Does It Work?

Three Steps. No Software. Honest Results.

1

Connect Device

Plug in your device via USB, connect via Bluetooth, or pair your 2.4GHz wireless receiver. Most peripherals are ready immediately. No driver installation needed for browser-based testing.

2

Choose Your Test

Select the peripheral category that matches your device. Each test page loads a model-specific layout or interactive diagnostic surface, depending on the peripheral type.

3

Read the Feedback

Visual indicators flag exactly which key, button, pixel zone, or axis is misbehaving.

Keyboard Issues

Unresponsive keys, key chatter (double-typing from a single press), ghosting under simultaneous key presses, N-key rollover failures, and stuck modifier keys. If a switch stops registering before it physically fails, it shows here first.

Mouse Issues

Double-click faults from degraded switch contacts, missed clicks, scroll wheel skipping, polling irregularities, and unresponsive side buttons. Competitive and productivity users often discover switch wear before they notice it in-game.

Monitor Issues

Dead pixels (permanently off), stuck pixels (locked to a single color), backlight bleed, color uniformity drift, and response-time artifacts on high-refresh displays. Running a pixel test before a return window closes has saved users hundreds in shipping costs.

Gamepad Issues

Analog stick drift caused by worn potentiometers, ghost inputs from dirty button contacts, asymmetric trigger response, and deadzone miscalibration. The browser Gamepad API reads raw axis values, so the drift that games compensate for still appears in the tester.

Headset Issues

Left-right channel imbalance, microphone cutouts, frequency response gaps, and connection drops on wireless models. Audio channel isolation tests separate hardware faults from driver conflicts.

Webcam Issues

Black screen on startup, low frame rate output, autofocus failure, and incorrect resolution reporting. Browser-based webcam testing uses the MediaDevices API and confirms output independent of your video conferencing software.
