3K Wallpaper Black
Between Full HD and 4K lives 3K — and this shelf keeps black files with resolution to spare: a 5K black hole, MKBHD-style abstracts, monochrome forest light. Free to download.
3K is shorthand for screens sharper than 1080p but shy of full 4K — a lot of laptops and mid-range monitors live exactly there, and files with extra resolution headroom serve them best. The picks lean premium: a black hole render made at 5K, glossy 3D abstracts, black-and-white photography with grain worth keeping. Wide frames dominate. Open the full-size file before judging any of these — the detail is the point. Right-click, Save image as, set as background. Free for personal use, no watermark anywhere.
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.
