Dual Monitors: Unique Wallpapers for Each Screen

Utilizing Distinct Wallpapers Across Multiple Monitors
Note: This guide has been revised and is applicable to both Vista and Windows XP operating systems.
The increasing prevalence of multi-monitor setups is a reflection of modern computing power. Today’s computers readily handle numerous applications simultaneously, often exceeding the available screen real estate. Consequently, upgrading to a dual-monitor configuration is a logical step for many users.
Addressing the Default Wallpaper Issue
A common initial observation when using multiple displays is that the same wallpaper image is replicated across all screens. This can be particularly noticeable when pairing a laptop with an external monitor, especially if they have differing resolutions. The secondary screen may then display a distorted, "squashed" version of the intended image.
Leveraging Desktop Items for Customized Backgrounds
A solution to this issue involves utilizing Desktop Items. Specifically, creating a web item allows you to designate a unique image for each monitor. The following steps detail how to achieve this customization.
Begin by accessing Display Properties. From there, navigate to Customize Desktop, and then select the Web tab, as illustrated.
Adding a New Wallpaper
Click the "New" button. A dialog box will appear, prompting you to choose between a webpage or a wallpaper. While utilizing a website as a wallpaper is an option, our focus is on background images. Browse to and select your desired wallpaper file.
For example, you might choose "Heart Broken" by Pincel3d, who offers a variety of other visually appealing wallpapers.
Now, a slightly nuanced step follows. You will observe an item appear on your desktop. Depending on your existing wallpaper, it might be subtle. Position your mouse cursor near the top of the newly added image.
You should then see a visual element similar to this. (Note: the image has been resized for clarity.)
Drag the title bar of the image to the monitor you wish to adorn with the wallpaper. Subsequently, click the Maximize button. The wallpaper will then seamlessly cover the entire window of that monitor.
Securing the Wallpaper and Finalizing the Setup
To prevent accidental repositioning, right-click on the desktop and select "Lock Web Items on Desktop." This ensures the image remains fixed in place.
With these steps completed, you will now enjoy distinct wallpapers on each of your monitors – potentially even across three or more displays!
