I've been using Lightroom for several weeks now. Yesterday morning, I made a setting change from medium to high in regards to the slideshow. Once I made that change, now a few images come in sharp, but for the most part, they are all fuzzy rendering. It doesn't do any good to even attempt to view them. For the life of me, I cannot figure out where I made the change to set it back to "medium".
Anyone have a handle on this? Thanks in advance. It's starting to get under my skin, that I cannot find this. The help doesn't have anything about it.
