Slideshow wallpaper displaying as span when set to fit

I have my wallpaper setting running as a slideshow on Windows 10 set to Fit. I'm fine with displaying different images on each monitor, but after a little while it will start displaying only one centered between the monitors as though it's set to Span.
As soon as I open the Settings app to fix it, the background resets itself and goes back to working correctly. Any solutions would be helpful.

 

Resizing Wallpaper on my N8 to fit my home screen

I've noticed a problem on my N8. I cannot seem to fit the entire wallpaper on my home screen. I guess the problem is that the wallpapers are of larger resolution and whenever i set the pictures as my wallpaper the edges get cut off. Is there a way of fitting
the whole wallpaper to fit my screen. I tried editing by resizing the picture but it works on some pictures.

 

How to make pic fit the lock screen?

Hi Paul,

In order to see your lockscreen wallpapers in full view, the image itself must match with the aspect ratio of your monitor. If the image resolution exceeded the dimension size of your monitor, it would unlikely fit on your monitor screen. You need to edit
and resize your image until if fits on your screen. To do this, follow the steps below:

Step 1 - Reduce the image size by following these steps:

• Locate the image that you want to set as your lock screen wallpaper.
• Right-click the image, then click Edit. I will launch
  Paint.
• Click Home.
• Click Resize. Make sure that Maintain aspect ratio is checked.
• Reduced the percentage size by changing the Horizontal and Vertical until you determine that it will fit on your lock screen.

Step 2 - Edit the image to fit in your lockscreen by perform the steps below:

• Press Windows + S to open Search Box.
• Type Photos, then click it to launch this application.
• Locate the image that you want to edit.
• Click the image.
• Press Ctrl + E to start editing.
• Click Crop.
• On the top right, click the Aspect ratio menu.
• Click Lockscreen.
• Click the check sign to apply changes.
• Press Ctrl + S to save the image.

There is no shrink or expand image option available in Lockscreen settings since Windows 10 can already automatically resize the image to fit on your screen.
