White Screen
Free full screen pure white (#FFFFFF) for your monitor, laptop, TV or phone. Use it to find dead pixels, light your face on video calls, trace drawings or check your screen's tint, with warm and cool light tones.
What Is A White Screen Tool?
A white screen tool fills your whole display with pure white, color code #FFFFFF, with no browser bars or cursor in the way. It turns any screen into an even, bright surface for finding faults, lighting a scene or tracing.
Pure white sets every red, green and blue sub-pixel to full level, so the screen gives off as much light as it can. That makes a dead pixel, one that cannot light at all, show up as a small black dot. It also exposes uneven areas, such as darker corners or a pink or green tint on one side, because there is nothing else on screen to distract your eye.
The same bright, even surface works as a soft light source. A tablet becomes a light box for tracing, a second monitor becomes a fill light for video calls, and a phone becomes a gentle flashlight. The warm and cool tones on this page change the color of that light, from candle-like 2000K to bluish 10000K.

A white screen will not damage your display, and short use is fine for your eyes. In a dark room, though, full brightness can feel glaring, so lower it or use a warmer tone.

Bright white against a dark room is tiring. Turn on a lamp, lower the brightness or choose Warm White.
Safe For LCD Screens
On an LCD, the backlight runs at the same level whatever the picture, so white causes no extra wear.
OLED Dims Full White
Most OLED TVs and many OLED monitors lower brightness on a full white screen to control power and heat. That is normal.

Long hours at maximum brightness age OLED pixels faster, but even white ages them evenly, without a burn-in pattern.

Phone testWhite Screen FAQ
Answers to what people ask most about using a full screen white page.
What is a white screen?
A white screen is a page that fills your display with pure white, color code #FFFFFF. People use it to find dead pixels, light their face on video calls, trace drawings, check screen tint and uniformity, and as a soft light in the dark.
How do I make my screen completely white?
Press Full Screen on this page, or press F on a keyboard. The browser bars disappear and the whole display turns white. Move the mouse or tap to bring back the controls, and press Esc to exit.
What is the color code for white?
Pure white is #FFFFFF in hex, or 255, 255, 255 in RGB. Every red, green and blue sub-pixel is at full level. The standard sRGB white point is D65, which is close to daylight at about 6500K.
Can I use a white screen as a light for video calls?
Yes. A bright white screen in front of you works as a soft fill light for your face. Open it on a second monitor, laptop or tablet behind your webcam, turn brightness up, and use a warmer tone if the light looks harsh.
How do I find dead pixels with a white screen?
Open pure white full screen at normal brightness and look slowly across the display. A dead pixel shows as a small black dot that stays dark. Then check other colors with the Dead Pixel Test to confirm it.
Why does my white screen look yellow or blue?
Your screen white point, color temperature setting or a night mode filter changes how white looks. Turn off Night Light, Night Shift or True Tone, and check the color temperature setting on your monitor or TV.
Why does my OLED screen get dimmer on a full white screen?
Most OLED TVs and many OLED monitors limit brightness when a large area is bright, called automatic brightness limiting. A full white screen is the hardest case, so the panel dims it to manage power and heat. This is normal.
Is a white screen bad for your eyes?
A bright white screen in a dark room can feel glaring and tiring. Lower the brightness, use a warmer tone or turn on some room light. As a short-term light source or for tests it is fine for most people.
Can a white screen damage my display?
No. Showing white is normal use for any screen. On OLED, very long periods of full white at maximum brightness age the pixels faster, but because the image is even, it does not create a burn-in pattern.
Can I use a white screen for tracing?
Yes. Lay a tablet flat, set it to pure white at full brightness, place the original under thin paper and trace. Put a clear plastic sheet on the screen first to protect it, and do not press hard.
