White Screen
A white screen is a fullscreen white display that turns your computer monitor, phone, or tablet into a bright, clean white surface. This simple tool can be used for many different purposes, including cleaning your screen, checking for dead pixels, providing lighting for video calls and photography, creating a white background, and more.
Our free white screen online tool works directly in your browser. You don’t need to download or install anything, and no sign-up is required. Simply open the tool, choose the color or settings you need, and use the display in fullscreen mode.
Whether you need a white screen background for a video call, want to check your monitor for dust and smudges, or need a temporary light source for creative work, a fullscreen white display provides a clean and distraction-free surface.
The tool also includes features such as adjustable brightness from 10% to 100%, color temperature control from cool to warm, OLED burn-in protection, Keep Awake mode, multiple color options, a pixel grid overlay, and high-resolution white screen image downloads up to 8K.
Why Use a White Screen?
A white screen can be useful for several everyday and creative tasks.
Dead pixel test: A bright white background can make dark or stuck pixels easier to spot.
Monitor cleaning: Dust, fingerprints, and smudges become easier to see against a plain white background.
Lighting: Use the display as a soft light source for photography, video calls, online meetings, or other tasks.
Focus: A blank white display can provide a clean, distraction-free surface for reading, working, and visibility checks.
A white screen tester is a tool used to test your device’s display. Some users search specifically for a pure white screen, plain bright screen, or blank white screen when they want to check their screen for errors, color issues, or visible imperfections.
A white screen can also be used as a light source, background, wallpaper, or testing tool. In other situations, a blank white screen may appear unexpectedly on a phone or computer. These situations are different, so it’s important to understand whether you are intentionally opening a white screen or dealing with an unexpected display problem.
White Screen for Video Call Lighting
A white screen can work as a soft light source for Zoom calls, video conferences, online meetings, and other types of video communication.
If your room is dark or the main light is behind you, your face may appear darker on camera. A bright white display positioned in front of you can provide additional illumination and create a more natural appearance.
You can adjust the brightness and color temperature to find the lighting that works best for your environment.
White Screen for Screen Cleaning
A bright white screen makes dust, fingerprints, smudges, and other marks easier to notice.
Display a full white background on your monitor, phone, or tablet and inspect the surface carefully. The plain white color provides a consistent background, making small imperfections more visible.
After cleaning your screen, you can use the white display again to check whether any dust or marks remain.
White Screen for Dead Pixel Detection
A white screen test can help you inspect your display for dead or stuck pixels.
A dead pixel may appear as a small dark spot on a bright white background because it does not illuminate correctly. Stuck or defective pixels may also appear as small areas with a color that differs from the surrounding display.
For a more complete display test, switch between different solid colors, such as white, black, red, green, blue, yellow, or purple. Different backgrounds can make different pixel problems easier to notice.
A visual screen test can help identify visible issues, but it does not determine the exact hardware cause of a display problem.
White Screen for Photography and Video
A white screen can also be used as a simple fill light for photography and video.
Place your monitor, phone, or tablet near the subject and display a bright white background. You can adjust the brightness and color temperature to create the type of illumination you need.
A white display can be useful for:
- Portrait photography
- Product photography
- Video recording
- Webcam recordings
- Video calls
- Online meetings
- Selfies
- Small creative projects
A cooler white can provide a cleaner appearance, while a warmer color temperature can create softer-looking light.
White Screen Fullscreen
A full screen white display removes unnecessary visual elements such as browser menus, tabs, and other distractions.
Fullscreen mode can be useful when you need maximum coverage for:
- Lighting
- Screen cleaning
- Display testing
- Photography
- Drawing and tracing
- Reading
- Projection
A distraction-free white background
Open the white screen tool, activate fullscreen mode, and your entire display becomes a clean white surface.

How to Turn On a Full White Screen on Your Device
Follow these steps to enable a full white screen:
Visit the tool provider website, such as whitescreenstester.com.
Select the white color option.
Click the button in the lower-right corner of the screen to enable fullscreen mode.
The display will turn bright white.
Press Esc or click the X button to return to normal mode.

White Screen on Phone and Tablet
A phone or tablet can work as a portable white light or quick display-testing tool.
A phone provides a smaller light source, while a tablet offers a larger display area. Landscape mode can provide a wider surface, especially when the device is being used for lighting or display testing.
Brightness and color temperature controls can also help you adjust the screen according to the surrounding environment.
White Screen for Drawing and Animation
A white screen can be used to illuminate a drawing surface.
⚪ What is a white screen online tool?
The Online White Screen is a browser-based tool that allows you to find dead pixels on your monitor without installing any software. It displays a pure white screen (#FFFFFF), making it easier to identify dead or defective pixels.
The white screen can also be used for other purposes, such as cleaning your screen, providing additional lighting for video calls, reading, and other similar tasks.
⚪ How do I use a white screen to test for dead pixels?
To test for dead pixels using ScreenDock’s online white screen, first open the screen in white mode and switch to full-screen. Then, slowly scan your display from one corner to the other. If you notice small dark or black spots that remain unlit against the bright white background, they may indicate dead pixels.
For a more thorough test, follow the white screen test with a black screen to help identify stuck pixels, which are often easier to spot against dark backgrounds.
⚪ What’s the difference between a dead pixel and a stuck pixel?
A dead pixel remains completely dark regardless of the color displayed, especially on a white screen, because its transistor has failed and it no longer receives any electrical signal. In contrast, a stuck pixel is typically locked on a single color—usually red, green, or blue—and is much easier to spot against a black background than a white one.
Dead pixels are generally permanent, whereas stuck pixels may sometimes be fixed by gently applying pressure or using software that rapidly cycles through different colors.
⚪ Is the white screen online tool free to use?
Yes, ScreenDock’s online white screen tool is completely free to use. You can access all of its features directly through a web browser without signing up, subscribing, or installing any software.
You can also use the tool for a variety of purposes, including screen testing, screen cleaning, providing additional lighting, and other practical uses.
⚪ Can I use a white screen tool as a light source for Zoom or video calls?
Yes, the white screen tool provides bright, even lighting, making it an effective fill light for Zoom calls, video conferences, and webcam recordings. By positioning your device’s screen at eye level directly in front of you and setting it to a high brightness level, it can function like a small softbox, helping to reduce harsh shadows on your face.
⚪ Does a white screen help clean my monitor or phone screen?
Yes, displaying a completely white screen makes dust, smudges, fingerprints, and streaks on your monitor or mobile device much easier to see, as they stand out against the bright, uniform background. This makes it much easier to identify exactly where the screen needs to be cleaned compared to inspecting a screen that is turned off.
⚪ Does the white screen tool work on phones, tablets, and TVs?
Yes, the online white screen tool works on virtually any device with a web browser, including smartphones (iOS and Android), tablets, laptops, desktop monitors, and smart TVs. No special app or software installation is required. Simply open the tool directly in your browser, and the white screen can be rendered in full-screen mode for a more convenient viewing experience.
