About

Full Screen Test is an independent, solo-built collection of free tools for checking any screen — dead and stuck pixels, colour reproduction, brightness, uniformity, gradients and more. Every test runs entirely in your browser: nothing about what you test is uploaded, and there's no sign-up. It is not affiliated with any monitor or device manufacturer.

Privacy: the tests themselves never upload anything. This site is free and may show ads and use privacy-respecting analytics to cover its costs.
