Wallpaper not appearing on second display
If you have an external monitor and the wallpaper only shows on one screen, here's how to fix it.
1. Make sure both screens are detected
- Click the Apple menu > System Settings > Displays.
- You should see both monitors listed. If not, check your cable and try unplugging and reconnecting it.
2. Apply the wallpaper to the correct screen
LumaSpace supports per-screen wallpapers. When you apply a wallpaper, make sure you're targeting the correct display. Move your mouse to the second monitor and use the menu bar star icon to check the wallpaper status for that screen.
3. Re-apply the wallpaper
Open LumaSpace, pick a wallpaper, and apply it specifically to the second screen using the display selector.
4. Restart LumaSpace
Quit LumaSpace (right-click in the Dock > Quit, or press Command + Q) and reopen it. This forces it to detect all connected screens fresh.
5. Check your cable and adapter
Some display adapters or cables can cause issues. If possible, try a different cable or port.
