How to Span a Wallpaper Across Multiple Monitors

When setting up a computer for the first time, a lot of users will customize their desktop wallpaper to add their own personal touch to their device. By default, multiple monitor setups will repeat the wallpaper chosen on all the monitors. But in this blog, we are going to show how you can find and use wallpapers that span across your multiple monitors, which can create a unique looking desktop background for your setup!

For Best Results

First, a disclaimer. Setups like these with a background spanning multiple monitors tend to work best with displays of identical screen size, orientation, and resolution. These backgrounds may look distorted or misaligned if spanned across monitors where one or more of these traits are different. Some paid utilities such as DisplayFusion can help in these scenarios, but we will not be diving into that today.

As an example, I will be showing a setup with two 1920 x 1080 displays on Windows 11, but the same steps can be applied for Windows 10 (notes for macOS users down below).

Choosing a Wallpaper

The first step will be finding a wallpaper that you would like to span across your monitors. While any wallpaper will work, a good rule of thumb is to look for a wallpaper with a resolution of all of your monitors combined. For example, if you have two 1920 x 1080 monitors side by side, a 3840 x 1080 wallpaper will span these monitors perfectly without any cropping or distortion.

Below is a table with some common multi-monitor resolutions:

Combined Resolutions of Common Multi-Monitor Setups
	モニター数
Resolution of Each Display		1920 x 1080	2560 x 1080	2560 x 1440	3440 x 1440	3840 x 2160
	2	3840 x 1080	5120 x 1080	5120 x 1440	6880 x 1440	7680 x 2160
	3	5760 x 1080	7680 x 1080	7680 x 1440	10320 x 1440	11520 x 2160

Because this setup has two 1920 x 1080 displays, I found this wallpaper that had a resolution of 3840 x 1080, simply by searching for “3840 x 1080 wallpaper” in a search engine.

Changing The Background

Once you have your wallpaper chosen, we’ll want to access the ‘Background’ settings. To do this, simply right click your desktop and select ‘Personalization’. Once in the Personalization menu, select ‘Background’ which should be the first option.

Next, you can select ‘Browse Photos’ and select the wallpaper that you picked out.

Spanning The Image

The final step to making this image span across your monitors is to navigate to ‘Choose a fit for your desktop image’ and select ‘Span’.

And that’s it! You now should have a wallpaper that spans across your displays. Here are the results of this example:

For Mac Users:

This ability to span a wallpaper across multiple monitors is unfortunately not natively supported on macOS. However, there do appear to be some utilities that people have created to allow Mac users to do this. My favorite is Fresco, which is a free app that allows you to span an image across your displays, while also adding some other functionalities to setting up your desktop background! The main page linked above has a number of tutorials to help you understand the capabilities of this app.
