An image cropped to the proper size. You can find the display resolution for all iPad and iPhone models on Apple's Manuals, Specs, and Downloads webpage.
Jamf Pro sends a Set Wallpaper command the next time mobile devices in the smart group check in with Jamf Pro.
The first time you set the wallpaper on devices with iOS 16 or later or devices with iPadOS 17 or later, the wallpaper is applied to both the Lock Screen and Home Screen. After the initial wallpaper configuration, you can set the wallpaper on the Lock Screen and Home Screen separately.
After a mobile device joins a smart group, the Set Wallpaper command is sent immediately. If a mobile device is a member of multiple smart groups and each smart group has a Set Wallpaper command, multiple Set Wallpaper commands will be sent to the device in the order the device joined the smart groups.
