About Dead Pixel Test

Dead Pixel Test is a free, independent tool that helps you check any screen for dead pixels, stuck pixels and burn-in in a minute or two. There's nothing to install, no account and no cost. It all runs right in your browser.

There are no ads, no sponsored links and no tracking cookies. We count page views with Cloudflare Web Analytics, which doesn't use cookies, doesn't give you an ID and doesn't follow you to other sites. The tests themselves send nothing anywhere. If any of that ever changes, we'll update this page and the privacy policy first, so they always say exactly what the site does.

Want to check your speakers or headphones too? Sound Test tests left and right channels, bass and your microphone, right in the browser.
