WhiteScreen - Full Screen Online Test WhiteScrn
Our Story

Built for everyone, free forever.

WhiteScrn was born from a simple idea — your screen is already a powerful tool. We just make it easier to use.

Our Mission

To give every person with a screen — a photographer, a remote worker, a gamer, a parent — a free, instant, and reliable fullscreen display tool that just works, on any device, without any login or download.

What is WhiteScrn?

WhiteScrn is a free, browser-based fullscreen color display tool. With a single click, it transforms any monitor, laptop, tablet, or smartphone into a pure, uniform color surface — no downloads, no account, no ads.

Whether you need a bright white light for photography, a black screen for OLED pixel testing, a warm glow for Zoom calls, or any custom color for display calibration — WhiteScrn has you covered instantly.

What We Believe

Free, Always

WhiteScrn will always be free. No subscriptions, no paywalls, no ads. A useful tool should be accessible to everyone, everywhere.

Instant & Simple

Open the page, click a color, go fullscreen. No login, no setup, no instructions needed. It works the way you expect it to.

Privacy Respecting

We collect no personal data and store nothing on our servers. Your screen, your session — completely private.

Who Uses WhiteScrn?

Photographers

Use any screen as a portable softbox or fill light for product shots, portraits, and macro photography without extra gear.

Display Testers

Check for dead pixels, backlight bleed, color uniformity, and panel defects using solid color screens across the full spectrum.

Remote Workers

Improve webcam exposure and look polished on Zoom, Teams, and Google Meet calls using Zoom Lighting mode — no ring light needed.

Screen Cleaners

A bright solid color screen makes dust, fingerprints, and smudges immediately visible so you can clean your display thoroughly.

Presenters

Blank your display to a clean solid color during presentations or events to keep audience focus where it belongs — on you.

Night Users

Red and warm-yellow screens preserve night vision and reduce eye strain for astronomers, late-night workers, and readers.
