Free 4K live wallpapers sized exactly 1290 × 2796 for the iPhone 15 Pro Max (6.7") — no crop, no watermark. Set a moving lock screen in one tap on iOS 17.
Save the wallpaper to your iPhone 15 Pro Max
Open it in 2Live and tap Save. The file arrives at the exact size of your screen, so iOS never re-crops it.
Set it as a Live Photo lock screen
Settings → Wallpaper → Add New Wallpaper → Photos, pick it, then tap the Live Photo icon so it plays on wake. Drag the subject down slightly so the Dynamic Island does not clip it.
1290 × 2796 pixels on a 6.7" display — an aspect ratio of about ≈19.5:9. Anything smaller is upscaled by the OS and looks soft; anything a different shape gets cropped.
Yes. iOS 17 sets a Live Photo as the lock screen, and it plays whenever the screen wakes. That is what 2Live makes — the wallpaper actually moves, which is the one thing saving a picture from a web page cannot give you.
On an OLED panel a true-black pixel is a pixel that is switched off, so a genuinely black wallpaper draws less power — which matters most on a device that keeps the display on. That is why the AMOLED collection leads this page.
