About Dead Pixel Test
Free full-screen dead pixel test in your browser
A no-install way to inspect a new monitor or phone screen. Dead Pixel Test displays solid colors in your browser so you can look for dots that stay dark, bright or one color as the background changes. The inspection is manual: the browser cannot read the physical condition of display pixels or diagnose a hardware defect. The site explains dead and stuck pixels and suggests checking the seller’s return terms or the manufacturer’s pixel policy if a defect persists.
