Windows 10: Wallpaper across all monitors

You've finally found a nice, high-resolution photo for your PC, but as a wallpaper it doesn't span across all monitors. Every single screen shows the wallpaper completely, instead of showing only a part of the whole picture..

As a workaround, do the following on Windows 10:

  1. go to the Settings of Windows 10 (e.g. via Windows key + I).
  2. select Personalization (background, lock screen, colors).
  3. under Select customization, select the "Stretch" option.

You only need to make this adjustment once. Now select the background image as usual:

  1. using File Explorer, go to the folder where the image file is located.
  2. right-click** on the image file to open the context menu and select Set as desktop background.

Now the selected background image will span across all monitors.
