#FFFFFFHow to Open a Fullscreen White Screen
Select White for a pure white background (#FFFFFF), then click or tap the large preview. The screen fills with white when your browser allows fullscreen. On a keyboard, press F to toggle fullscreen; click the screen again or press Esc to exit.
You can also choose black, red, green, blue, yellow, orange, pink, or enter a six-digit HEX color. If your browser does not support the Fullscreen API, the tool can fill the browser window instead, although tabs and address bars may remain visible.
What Can You Use a White Screen For?
Screen cleaning: A bright white background makes fingerprints, dust, and streaks easier to spot. Use it to inspect the display, then turn the device off before cleaning it according to the manufacturer's instructions. Don't spray liquid directly onto the screen.
Tracing and drawing: Put a thin sheet of clean paper over a bright screen to see a reference underneath. Use minimal pressure, and keep sharp tools away from the glass. A dedicated lightbox is better for regular tracing.
Blank backgrounds: Turn a spare monitor or tablet into a plain white background for photographs, presentations, or a distraction-free second display. Switch to black or another solid color when white isn't suitable.
White Screen Test for Dead Pixels and Display Issues
A white screen can help reveal dark pixels, uneven brightness, or discoloration. For a more useful dead pixel test, examine the same area on white, black, red, green, and blue backgrounds. A point that stays dark or shows the wrong color on several backgrounds may indicate a pixel or subpixel issue.
First check for dust, reflections, and marks on the glass; these can look like defective pixels. Solid colors are useful for visual inspection, but they cannot diagnose a fault, fix a stuck pixel, or calibrate a monitor.
Which Screen Color Should You Check?
Compare several solid colors rather than relying on white alone.
| Color | Useful for | What to look for |
|---|---|---|
| White | Dark pixels, dust, smudges, uneven brightness | Look for dark dots, marks, tinted patches, or dim areas. |
| Black | Bright pixels, backlight bleed, visible glow | In a dim room, look for bright dots or unusually bright edges. |
| Red | Red subpixel problems | Look for dots that stay dark or show an unexpected color. |
| Green | Green subpixel problems | Check whether the same spots look different from nearby pixels. |
| Blue | Blue subpixel problems | Look for dark or discolored dots against the blue background. |
Use a White Screen as Light for Video Calls
A white screen can provide extra light for a webcam, Zoom meeting, or quick photograph. Open Video Call Lighting to move between warm off-white and neutral white, then position the display near your camera to soften shadows on your face.
The Intensity slider darkens or brightens the color shown by this page. It does not change your device's hardware brightness. Adjust that separately, and avoid a setting that causes glare or eye discomfort.
Download a White Background PNG
Choose White to create a solid #FFFFFF image, or pick another color and enter an exact six-digit HEX value. Select Download PNG to save the result. The image is created in your browser without uploading a source file.
Available sizes include 1920 × 1080 (Full HD), 3840 × 2160 (4K), and 7680 × 4320 (8K). You can also enter custom width and height values, up to 7,680 × 4,320 pixels. Very large images may fail on devices with limited browser memory; try a smaller size if necessary.
Practical Examples
Check a suspicious pixel
Open white, black, red, green, and blue in fullscreen. Examine the same location on each background.
A consistently dark, bright, or mismatched point is worth checking against your display manufacturer's pixel policy.
Create a 4K white background
Select White, choose the 4K preset, and click Download PNG.
Save a 3840 × 2160 PNG filled with #FFFFFF for a slide, video, or design.
Frequently Asked Questions
Why are my browser tabs still visible?
Some browsers cannot enter true fullscreen. In that case, the tool may fill the browser viewport while tabs or the address bar remain visible.
Does the white screen work on phones and tablets?
Yes, the page adapts to mobile screens. Fullscreen behavior varies by browser, and some devices may show browser controls.
Can this make my display brighter than its maximum setting?
No. #FFFFFF is a white digital color, not an override for the screen's hardware brightness. Use your device's brightness controls to adjust the light output.
Will the white screen stop my device from sleeping?
In true fullscreen, the tool tries to keep the screen awake while the page is visible. The browser or operating system can deny or end that request, so it is not guaranteed.
Can a white screen repair dead or stuck pixels?
No. It can help you spot possible pixel issues using solid colors, but it cannot identify their cause or repair the display.
Is a bright white screen safe for OLED displays?
Avoid leaving a bright, static image on an OLED display for long periods. Use a comfortable brightness and close the screen when you finish.
