About This Tool

Purchasing a new computer monitor, laptop, or television is a significant investment, and discovering a manufacturing defect after the return window has closed is incredibly frustrating. Our Dead Pixel Test is an essential diagnostic tool designed to help you instantly identify any malfunctioning pixels on your LCD or OLED displays. The tool utilizes a full-screen, high-brightness interface that cycles through pure primary colors—solid red, green, blue, white, and black. By meticulously examining your screen against these solid backgrounds, you can easily spot 'dead' pixels (which remain permanently black) or 'stuck' pixels (which remain permanently lit with a single color). This is highly practical for everyday consumers testing a brand-new device out of the box, or for gamers and graphic designers ensuring their expensive hardware is performing flawlessly, allowing you to confidently process warranties or returns before it is too late.
