Black Screen is a free, browser-based utility for fullscreen display testing, OLED burn-in prevention, and distraction-free focus, offering downloadable images from 480p to 8K.
What is Black Screen?
Black Screen is a free online tool that turns your browser into a fullscreen canvas of a single color — black, white, red, green, blue, yellow, orange, pink, purple, or any custom hex. It runs on any device with a modern browser (desktop, tablet, phone) and requires no installation or registration. The tool is hosted at Black Screen and maintained by its development team. Users select a color, optionally set a timer, enable OLED protection, or download an image of the current screen at a chosen resolution (480p to 8K, including custom dimensions). The output is either a live fullscreen display for testing or focus, or a downloadable PNG image.
