Win10 defines a solution to the black background problem on the desktop background.

When a user uses the Win10 system, after customizing the wallpaper of the desktop background, it is found that there is a black border on the top and bottom. This is because the size of the wallpaper image used does not match the current screen resolution, resulting in black borders around the desktop. How to solve it?

Solution

In the first step, hit the right mouse button on the blank space of the desktop, and click “Personalize” in the menu.

The third step is to set the interface on the desktop background, set the image placement mode to "Stretch" or "fill & rdquo;, then click “Save Changes”.

Although this can eliminate the black border of the desktop background, it will affect the image display. It is better to use the original size and the screen resolution to make the wallpaper.
