Configuring Separate Wallpapers for Multiple Monitors

You've scoured through the control panel looking for a way to configure different wallpapers for each of your monitors, but alas, your search availed nothing.

Unfortunately this feature was never programmed into windows. The wallpaper settings apply to all the monitors at once. Boring.

Fortunately, it can be done, and this instructable will show you how

Note: There are third-party software programs that can configure separate wallpapers; this Instructable shows you how to do it without them.

Step 1: Prepare the Wallpapers

The first thing you need to do is to resize each wallpaper so that they have the same dimensions as the monitors they are going to be on.

Tip: You can save these images as PNGs to minimize JPEG artifacts. They are temporary so filesize does not matter.

Step 2: PrintScreen

Open and Maximize an instance of Notepad on each monitor. (this is not absolutely necessary, but it will make your life much easier)

Press Print screen.

Open Microsoft Paint.

goto image properties and change the Width and Height to 100 (this is recommended but it may not be necessary)

Right click > Paste

What you end up with is a gigantic picture of all of your screens. be sure to note which screen is the main screen (It's the one with the taskbar), and be sure to note the dimensions of this image.

Step 3: Add the Wallpapers

paste the wallpapers into the image and align them so that they perfectly cover their respective screens.

Step 4: Tile the Image

Make a 2x2 tile of the image so that the width and height are doubled.

Step 5: Align the Main Screen to the Top Left Corner

select all and drag the so that the main screen's wallpaper is alligned to the top left corner (this should leave some whitespace around the bottom and/or the right side of the image)

If the main screen's wallpaper is already aligned to the top left corner, than skip this step.

Step 6: Finishing the Image

go into the image properties and set the width and height to the values you noted in step 2. (this should crop the bottom and the left side of the image off)

Save the image; it is your wallpaper.
