How to use a different wallpaper on each monitor

A second monitor doubles your workspace, but by default most computers simply repeat the same wallpaper on every screen. With a few clicks you can give each display its own image, or stretch one wide panorama across all of them so your desk reads as a single window onto a landscape.

Windows 11 and Windows 10

Download one wallpaper for each screen first, ideally in each monitor's own resolution. Then open Settings → Personalization → Background and set “Personalize your background” to Picture. Your recent images appear as thumbnails. Right-click a thumbnail and choose Set for monitor 1 or Set for monitor 2. Repeat for each display.

If your monitors have different resolutions, choose Fill under “Choose a fit for your desktop image”. Windows will crop each image neatly rather than leaving black bars.

Spanning one image across several screens on Windows

To run a single panorama across all your monitors, choose Span as the fit. Windows treats your displays as one wide canvas. Add the widths together to know what size you need: two 1920 × 1080 monitors side by side form a 3840 × 1080 canvas, and three form 5760 × 1080.

Spanning works best when the monitors share the same height and resolution. If one screen is taller or sits lower than the other, the horizon will appear to “step” between them. You can soften that by lining the screens up physically and in Settings → System → Display, where you can drag the monitor icons to match their real positions.

macOS

On a Mac each display can already have its own wallpaper. Open System Settings → Wallpaper. With more than one display connected, the settings let you pick which display you are changing. Choose a display, select Add Photo or a folder, and pick your image. Set the image to Fill Screen so it isn't letterboxed.

macOS has no built-in “span” option. To spread one image across two screens, split it into two halves in any photo editor, each matching one display's resolution, and set them separately. Desktop utilities can also automate this if you change wallpapers often.

Choosing images that work as a pair

• Match the light. Two images shot at the same time of day sit together far better than a sunrise next to a midnight scene.
• Keep one calm, one busy. If your main screen holds windows all day, give it the quieter image and let the side screen carry the detail.
• Use a series. Photographs from the same location or photographer, or two paintings by the same artist, look intentional rather than random.
• Mind the bezel. When spanning, avoid images where the main subject falls exactly in the middle. It will be cut in two by the frames of your monitors.

Resolution checklist

Each screen should get an image at least as large as its own native resolution. A 2560 × 1440 monitor needs a 2560 × 1440 (QHD) image or larger, and a 4K monitor needs 3840 × 2160. Every wallpaper on this site offers these sizes ready-cropped, so you can download a matching pair in seconds.
