Tool Introduction
This turns your screen into a plain white panel you can view at any size, or go fullscreen with one click. A solid white surface makes dust, fingerprints, and streaks on your monitor stand out, helps you spot dead or stuck pixels, and works as a rough fill light when a webcam or camera needs a bit more brightness on your face. It also makes a clean white backdrop if you need to hold something up to the screen for a quick photo or video call.
How to Use the White Screen
- The panel loads as solid white by default
- Click "Go fullscreen" (or press F) to fill the entire display
- Move your mouse or press any key to bring the controls back if they fade out
- Use arrow keys or number keys 1 to 9 to switch between color presets
- Pick a different preset or your own custom color if you need one
- Press Esc, or click the fullscreen button again, to exit
Use Cases: Cleaning, Lighting, and Screen Checks
- Clean a monitor or laptop screen while dust and smudges are easy to see
- Check a new or used monitor for dead or stuck pixels before you keep it
- Add fill light to your face during a video call in a dim room
- Use it as a bright backdrop for quick product or macro photos
- Compare screen tint or yellowing against a known white reference
- Turn a spare monitor or tablet into a simple whiteboard-style backdrop

FAQs
Why would I need a plain white screen?
A full white screen gives you an even, bright surface. It is useful for spotting dust and smudges on a monitor before cleaning, checking a screen for dead or stuck pixels, and acting as a simple light source for video calls or product photos.
Can I use my screen as a light for video calls or photos?
Yes. A bright white screen close to your face works like a basic softbox, filling in shadows on video calls and adding fill light for close-up photos or short videos. It will not replace a real light, but it helps in a pinch.
How do I check for a yellow or tinted screen?
Put the screen in fullscreen white and look at it next to a sheet of white paper or another display in good lighting. A true white should look neutral. If it leans yellow, blue, or pink compared to the paper, the panel has a color tint.
Will this help me spot dust on my monitor?
Yes. Dust, fingerprints, and smudges show up clearly against a solid white background, especially under bright room light. Go fullscreen, then look at the screen from a slight angle to catch reflections and specks you would otherwise miss.
Does the screen turn off my computer while in fullscreen?
No. On supported browsers, the tool asks your device to stay awake while the white screen is active, so it will not dim or lock mid-task. It quietly does nothing if your browser does not support this.
Can I use a color other than white?
Yes. The panel includes red, green, blue, cyan, magenta, yellow, grey, black, and a custom color picker, plus a dedicated dead pixel test mode that cycles through colors automatically.
