About Black Screen
Black Screen is a collection of practical display tools that work directly in a web browser. The goal is simple: open the right screen quickly, understand the controls and know what the result can and cannot tell you.
What the site provides
The site includes solid color screens, display checks, screensavers, ambient video screens, timers, noise tools and clearly labelled simulations. Most tools are free to use without an account or software installation.
The Black Screen tool is the main starting point. It can fill a display with pure black, compare nearby shades and create a PNG in a chosen size. Related pages serve a specific purpose instead of repeating the same instructions under a different title.
How we build and review tools
A tool is tested for its main controls, fullscreen exit, mobile layout and clear status messages. Content is reviewed for accuracy, plain language, repetition and search intent before a page is approved for indexing.
Display checks are visual aids. They do not replace calibrated equipment, a repair technician or the device maker's instructions. Pages explain these limits where they matter.
Privacy by design
Color choices, generated images, QR code content and optional camera previews are handled in the browser wherever the tool allows it. Camera access requires permission and the preview is not recorded or uploaded by Black Screen.
Read the Privacy Policy and Cookie Policy for details about browser storage, hosting logs, fonts and future advertising services. The Terms explain the conditions for using these tools.
Questions and corrections
If a control does not work, a statement needs correction or an attribution appears to be missing, email contact@black-screen.dev. The Contact page explains what to include so the issue can be checked accurately.
