About WhitestScreen.com
WhitestScreen.com builds free, browser-based screen tools for cleaning your monitor, checking pixels, and lighting video calls. Every tool runs entirely in your browser: nothing you do on this site is uploaded anywhere.
How the tools work
Most tools fill your screen with a solid color you choose, with controls for brightness, color temperature, and a few display-specific features like OLED burn-in protection and a pixel grid overlay. Colors and settings are handled entirely on your device using standard browser APIs, so there's no server processing involved, and nothing is saved between visits.
Browse all the screen tools, or start with the screen guides if you're not sure which test you need.
