Pixel defects on a display can undermine every task, from critical design work to gaming sessions. Dead Pixel Test provides a fast, no-install way to verify screen integrity right in your browser. If a single dead or stuck pixel exists, you’ll know it in moments.
Core Value Proposition
With a full-screen color test and a zero-friction workflow, the tool helps you identify defective pixels quickly and confidently. It’s a lightweight, accessible solution built to work across devices, so you don’t have to guess whether your screen is reliable.
Key Features
-
Full-screen color test: Launch full-screen color swaths to reveal pixel anomalies across the entire display. The uninterrupted color fields stress the screen and make dead or stuck pixels easy to spot, even on subtle brightness differences.
-
Detect dead pixels fast: The test highlights dead pixels as conspicuous spots, enabling rapid confirmation of non-emitting pixels. This helps you decide whether a panel needs calibration, repair, or replacement.
-
Identify stuck pixels clearly: Stuck pixels appear as persistent color dots that don't change with test patterns. The visual cues make it easy to distinguish stuck pixels from dead ones for accurate remediation decisions.
