About Screen Issues
browser tool to detect dead pixels and screen defects
A dead pixel is a pixel on your screen that has stopped working and remains permanently dark. A bright spot, on the other hand, is an area that glows even when it should be black. Backlight bleed is light leaking from the edges of an LCD screen, while screen burn-in leaves ghost images on the display. This free screen test tool helps you detect all of these issues by displaying pure solid colors — white, black, red, green, blue, and gray — across your entire screen. By cycling through each color, you can quickly identify whether your display has any defects. Use this tool on laptops, monitors, tablets, or smartphones to get a clear picture of your screen's health. The auto-cycle feature walks through all six colors hands-free, so you can step back and inspect your screen from a distance. Whether you just bought a new device or want to check an existing one before returning it, this tool gives you an immediate and reliable diagnosis.
