Does your Desktop Wallpaper look similar to this?
If so, that means that the image you have set as your desktop wallpaper is too small for the resolution of your screen.
To prevent your wallpaper from becoming tiled, please choose an large image that is the same resolution as your computer screen. You can find the resolution of your monitor by going to the Start button , clicking Control Panel, and then, click the display icon (Appearance and Personalization on Windows 8 and 10), click "Adjust screen resolution".
There you will see your screen resolution and what size your image needs to be.

Select an image that is large enough to fill the screen. Once you have downloaded an image you would like to set as your Wallpaper, right click the picture and select "Set as Desktop Background"
