White screen FAQ
- What is a full white screen used for?
- Three things, mostly: turning your monitor into a soft light source for video calls and photos (crank the brightness and face the screen), spotting dead pixels — they stay dark against pure white — and judging panel uniformity, since tint shifts and dark patches show up most clearly on a white field.
- Why does my white screen look yellow, pink, or dirty?
- First disable Night Shift, Night Light, or any blue-light filter — they warm the whole screen on purpose. A uniform warm cast after that is usually the display's color-temperature setting. Blotches, streaks, or corners that differ from the center are the panel itself: uniformity issues or an aging backlight.
- Can a white screen damage my display?
- On an LCD, no — the backlight is on regardless of what's shown. On an OLED, hours of static full-brightness white contribute to long-term wear, but a test or a video call's worth is harmless. Just don't leave it on overnight at max brightness.
