This page is designed to help you find out whether CheckYourDisplay is good and if it is the right choice for you.
CheckYourDisplay is a free set of 53 browser tests for screens, speakers, headphones, microphones, webcams, keyboards, mice and game controllers. Everything runs in the browser: there is nothing to install, no account to create, and camera and microphone data stay on your device.
Display tests: dead and stuck pixels (plus a pixel fixer), refresh rate, ghosting, backlight bleed, screen uniformity, brightness, contrast, gamma, gradients, colors, HDR, burn-in, flicker, screen geometry, blooming and text clarity.
Audio and microphone tests: left and right speakers, headphones, balance, frequency response, bass, treble, distortion, speaker polarity, surround sound and audio latency, plus a microphone test, a recording test and a spectrum analyzer.
Input and camera tests: every key on a keyboard, mouse buttons, polling rate and DPI, touchscreens, pen pressure, gamepads and stick drift, webcams and the resolution your camera actually delivers.
Used Laptop Check: a guided checklist for a second-hand laptop, from the case, hinges and battery to the screen, keyboard, touchpad, speakers, microphone, webcam, Wi-Fi and ports. Mark each step Pass, Problem or Skip, then copy or print the report to take to the seller. It works just as well for shops and IT teams testing devices.
Device tools: screen resolution, pixel density (DPI), browser and WebGL support, phone gyroscope and vibration, and cleaning modes for screens, keyboards and speakers.
Guides explain how to test a new monitor, tell a dead pixel from a stuck one, fix a camera or microphone that a browser or app has blocked, and what to check on a used laptop or phone.

Used Laptop Check
Step-by-step checklist for a used laptop with a report to copy or print
It puts 53 hardware tests on one site, all running in the browser: screens, speakers, headphones, microphones, webcams, keyboards, mice, touchscreens, pens and game controllers. There's nothing to install and no account to create, and audio and video from your camera and microphone never leave the page.
Every test page also explains what the test can detect, how it works and where its limits are. The Used Laptop Check turns the individual tests into a guided checklist that ends with a report you can copy or print.
Many alternatives cover a single device type, or ask you to download an app first. CheckYourDisplay covers display, audio, microphone, camera and input tests in one place, runs in a modern browser on a computer or a phone, and needs no install or sign-up.
It's free, and it's upfront about what a browser can and can't measure, so you know when a result needs a second check.
People checking their own hardware:
It also suits repair shops, refurbishers and IT teams that need to check devices quickly.
The site is built with Astro and Preact and runs on Cloudflare Workers.
The tests use standard browser APIs: Web Audio, MediaDevices (getUserMedia) for the camera and microphone, the Gamepad API, Fullscreen, Pointer Events, Screen Wake Lock, Device Orientation and Motion, Vibration and WebGL.
