How to use the white screen
- Choose the white you want: plain, warm or cool. Lower the brightness if it is too much.
- Press Full screen. Your whole display turns that colour.
- Click or tap to bring back a small panel; press Esc, or its button, to leave.
Turn on Keep the screen on, where your browser offers it, so the screen does not dim or lock while you use it. For the most light, turn your screen’s own brightness all the way up too.
What people use a white screen for
- A light for video calls. A white screen in front of you lights your face evenly, like a soft lamp. Warm white is kinder to skin tones in the evening.
- Make-up and grooming, with the screen as a mirror light.
- Tracing a drawing or pattern on thin paper held against the screen. Keep the pressure light: pressing hard can damage an LCD screen.
- Cleaning the screen. Dust, smudges and streaks show up clearly against white.
- Checking for dead pixels, which show as dark dots on white.
Warm, cool and other colours
Warm white has a touch of yellow, like a traditional bulb, and cool white a touch of blue, like daylight. The other buttons fill the screen with black, red, green, blue or yellow, and Any colour lets you pick exactly the one you need, for example to match a backdrop or to test a single colour.
Brightness dims the colour itself, which is handy when full white is too harsh in a dark room. It cannot make the screen brighter than its own brightness setting.
Is a white screen bad for my screen?
No. Showing white is ordinary use for any screen. On OLED screens, very bright, unchanging images over many hours contribute to wear, so turn the white screen off when you are not using it rather than leaving it for days.
For the opposite, use the black screen. To check the screen for faults, use the screen test.
