I think you need a 3840×1080 to make it fill the second monitor otherwise if to try to strech a 1920×1080 across both monitors. If you can’t find a wallpaper that resolution you will have to strech it out to double the size and increase the resolution from 1920×1080 to 3840×1080
because if you don’t you are going to have 1920×1080 stretched out into 960×1080 per monitor so it is gonna end up looking weird because each pixel is still one pixel in the Y axis but it is gonna stretch 1 pixel into two pixels in the X axis.
