How to Change Wallpaper on Laptop

Changing Wallpaper on a MacBook (macOS)

System Settings:

• Click the Apple icon in the top-left corner of your screen and select System Settings (or System Preferences on older versions).
• Click on Wallpaper (or Desktop & Screen Saver) in the left sidebar.
• Browse through Apple’s built-in backgrounds or click Add Folder to select a custom picture from your folders.
• Click the image you want, and it will apply instantly.

Mac Books also support different wallpapers for the desktop and the lock screen, which can be set independently from the same Wallpaper settings page.

Setting Up a Slideshow Wallpaper

1. Open Personalize, then Background, as above.
2. Choose Slideshow from the dropdown.
3. Click Browse and select a folder containing the images you want to rotate through.
4. Set how often the picture changes, ranging from every minute up to once a day.
5. Choose whether pictures play in order or shuffle randomly.

A slideshow is a nice touch for a shared office laptop or a device used for demos and presentations, since it keeps the desktop looking fresh without any manual effort.

Choosing How the Image Fits Your Screen

Under Background settings, Windows also lets you choose how an image is displayed if it does not perfectly match your screen’s aspect ratio, with options including Fill, Fit, Stretch, Tile, Centre, and Span.

Fill is the most commonly used option, since it scales the image to cover the entire screen while cropping slightly rather than distorting the picture. Span is useful if you are using multiple monitors and want a single wide image to stretch across all of them.

Using Your Own Photos as Wallpaper

1. Save the photo you want to use somewhere easy to find, such as the Pictures folder.
2. Follow the standard Background or Wallpaper steps above and browse to that image instead of a default one.
3. If the photo came from your phone, you may need to transfer it to the laptop first. Our guide on how to connect phone to laptop covers both wired and wireless transfer methods for Android and iPhone.
4. Once transferred, the file appears in your Pictures folder or Downloads, ready to select as wallpaper through the same Background settings.

Fixing Wallpaper That Will Not Change

1. Make sure you clicked directly on the new thumbnail or picture and not just hovered over it, since a single click is required to apply the change.
2. Check whether your organization has a managed device policy in place, which can lock the wallpaper on work laptops and prevent personal changes entirely.
3. Restart Windows Explorer through Task Manager if the desktop appears frozen or unresponsive to any changes.
4. Confirm the image file itself is not corrupted by opening it separately in a photo viewer before selecting it as wallpaper again.
5. Update your graphics driver if the wallpaper appears to change in settings but the desktop visually stays the same.

If your screen shows odd colours or discoloured patches regardless of which wallpaper is set, that points to a display issue rather than a wallpaper setting, and our guide on laptop screen green tint problems is worth checking.

Check whether your organization has a managed device policy in place, which can lock the wallpaper on work laptops and prevent personal changes entirely. If you are checking or managing several devices, knowing how to check laptop serial number can also help identify the correct laptop.

Frequently Asked Questions

How do I set a different wallpaper for each monitor?

On Windows, right click the desktop, select Personalize, then Background, and choose a picture. With multiple monitors connected, right click a specific image in the picker and select Set For Monitor to assign it to just that screen.

Can I use a GIF or a video as my laptop wallpaper?

Standard Windows and macOS settings only support static images, though macOS does include dynamic wallpapers that shift gradually with the time of day. Live or animated wallpapers require third party software.

Why does my wallpaper look blurry after changing it?

This usually happens when the image resolution is lower than your laptop screen’s native resolution. Using a photo with a higher resolution, or matching your screen’s exact resolution, fixes the blur.

Does changing my wallpaper affect performance or battery life?

A static wallpaper has no noticeable effect. A slideshow with very frequent image changes, or an animated live wallpaper, can use a small amount of extra battery and system resources. You can also check laptop battery health if you notice unusual battery behaviour.

Can I lock the wallpaper so it cannot be changed?

Yes, on business or managed laptops, an administrator can lock the desktop background through group policy settings so individual users cannot change it.
