1080p is 1920x1080 as noted by https://en.wikipedia.org/wiki/1080p
Shutterfly photos look good on my new TV using the Shutterfly app on my Roku box. They have the aspect ratio of 16:9, but on the TV they don't show in that aspect ratio, they are cropped on each side. The TV is set to the 16:9 ratio, so that's not the problem. I tried compressing the photos, but that didn't change anything. I'm wondering if it would work with SmugMug.
