Black Waves Wallpaper 4K
Waves in the dark — flowing abstract curves and dark water, at Ultra HD. Community-shared; register to upload yours.
A wave is one long smooth curve of light bending across a dark surface, which makes it the single most banding-prone subject on this site: any re-compression turns that gradient into visible steps and the curve stops looking like it has volume. Native 4K and source quality are what prevent it, and both are kept here. Right-click to save at full size; free for personal use, no watermark.
Common questions
Do black wallpapers actually save battery?
On OLED and AMOLED screens, yes. A true-black (#000000) pixel is switched off rather than dimmed, so it draws no power — and with an always-on display that runs all day the difference is measurable. On an LCD screen it saves nothing, because the backlight stays on either way. Not sure which you have? Our OLED test tool fills the screen with pure black: on an OLED it goes completely dark, on an LCD you can still see the backlight glowing grey.
How do I set one as my wallpaper?
Long-press on mobile or right-click on desktop to save the image, then set it from your gallery or system wallpaper settings.
