Frequently asked questions
How do I make my screen completely white?
Click the Fullscreen button (or press F) on this page. Your browser will hide all toolbars and fill the entire display with pure #FFFFFF white. Press Esc to exit.
Can I leave the white screen on for 10 hours?
Yes. Enable Keep Awake to stop your device from sleeping, then enter fullscreen. The screen will stay pure white for as long as you want — overnight shoots, all-day softbox use, anything.
Is this white screen test free?
Yes — it's 100% free, runs entirely in your browser, requires no signup, and never uploads anything.
Will this damage my monitor?
No. A solid white image is no harder on a display than browsing a website with a white background. For OLED panels, lower the brightness if running for many hours.
