Questions
Does a white screen damage my display?
No. Showing white is normal use. On OLED screens, avoid leaving any static image on for many hours; the OLED button shifts brightness slightly to help.
How do I make it dimmer or warmer?
Use the brightness slider. For a warmer or cooler white, open the Zoom Lighting or Reading Light page, which have a warmth slider.
How do I keep the screen from going to sleep?
The page asks your browser to keep the screen awake while it is open. If your device still sleeps, change its power settings.
How do I use it as a light on a phone?
Open the page, tap once, press the fullscreen button and turn the phone brightness all the way up.
Why can I see a line or edge in fullscreen?
Some browsers show a small bar for a moment. Move the mouse away or tap again. The picture itself is a single flat color.
