Change Display Default

Hello! For some reason my display window shows images at 100% now (after download) which is way zoomed in. It used to show 10% (fit to screen) and I was able to see the entire image after it was downloaded. Now I have to tell it to fit to screen each time an image is downloaded. Something has changed. I don’t believe it was me, but I could be wrong. Thankyou. Screenshot included showing how I’d like it to be. Mine always shows up 24hr.
