I have version 7.5 of Lightroom Classic CC. I created a collection from the same trip to view as a slideshow. However, some of the pictures show up small on the screen while other show full screen. They are all .jpg type and have an aspect ratio of 4:3, with settings to FILL. Does anyone know why I don't have consistent sizes of the images displayed on my monitor. It doesn't seem to matter whether they are cropped photos or not.
