Frequently asked questions
How do I make my whole screen black?
Click Fullscreen (or press F) on this page. The browser hides toolbars and fills the entire display with pure #000000 black. Press Esc to exit.
Does a black screen save battery?
On OLED and AMOLED displays, yes — black pixels are switched off, which can significantly reduce power draw. On standard LCDs the backlight stays on, so savings are minimal.
Can I use this to fix OLED burn-in?
A long full-screen black session can help even out subtle image retention on OLED panels. For deeper burn-in, cycle full white and full black for several hours.
