WhiteScrn.com is a free white screen online tool that turns any device into a fullscreen white, black, or colored display for monitor testing, dead pixel checks, screen cleaning and Zoom lighting.

WhiteScrn.com is a free online utility that turns any laptop, monitor, phone, or TV into a fullscreen solid-color display in a single click. It's built for three main uses: running a white screen test to catch dead or stuck pixels and backlight issues, using the bright white screen as an even light source for Zoom calls, streaming or product photography and cleaning smudges and dust off a display where they're easiest to spot. Alongside white, the tool supports black, red, pink, yellow and other full-screen colors. It works instantly in any modern browser with no installs, signups or fees.
