About Screen Tester
Screen Tester is a free collection of online tests for monitors, laptops, TVs, phones and tablets. Every tool runs in your browser, with no sign-up and no download, so anyone can check a screen in minutes.
We build tests for the problems people actually run into: dead and stuck pixels, backlight bleed, burn-in, uniformity, viewing angles, sharpness and refresh rate, along with input tools for keyboards, mice, microphones and webcams. Each test page explains what to look for, what is normal and what to do next, so the results are useful when you decide whether to keep, return or claim on a screen.
The tests run on your own device. Your results, marks and reports stay in your browser unless you choose to share them. When you find a mistake or have an idea, this page is the fastest way to tell us, and every message is read by our team.
