bigger pictures for the Windows 10 App

In the dashboard view on Windows 10, is there anyway to make the pictures larger on the screen? I have a large 4K display that the app only uses a very tiny part of. I can streach the app to make it use more of the screen but the pictures all stay the same tiny size. The pictures are useless at the size in the dashboard currently on a large screen. They might work well on a small laptop but not a desktop with a large display. If I set the zoom on the entire monitor to 200% the pictures in the ring dashboard starts to become useful but the display is not useful for any other programs then. I would like to just leave the app running and up in the corner of the monitor showing the dashboard but without a larger image in the pictures it is not useful. Even better would be if the app used the full windows occupied by the app and lose the whitespace.
