About PixelRecovery
An independent project with one narrow goal: make screen diagnostics fast, free and honest.
What this site is
PixelRecovery provides browser-based tools for testing and repairing display defects: a dead pixel test, a stuck pixel fixer and a full monitor test suite. There is no account, no download and no server-side processing.
The tools are free and supported by advertising. Affiliate links, when present, are clearly labelled and never influence the test results.
How the tools work
Every test is rendered locally by your browser using standard HTML, CSS and Canvas. Nothing about your screen, your device or your session is uploaded. That is a deliberate design choice: the tools must keep working offline, on a locked-down work laptop, and on a phone with no app installed.
The fixer is based on the long-established principle of rapid color cycling. It is not a guaranteed repair, and we say so on every page that offers it.
Editorial approach
Repair advice is written to be useful before it is written to rank. Where a method is risky — pressure on the panel, for example — we say so. Where a repair is unlikely, we say that too, even when the honest answer costs us a page view.
If you spot an error, have a suggestion or want to report a tool that is not working on your device, write to us.
