If anyone is looking for a decent screensaver tool for Windows which will throw your astro images onto a dual monitor setup and doesn't use Ads, perhaps look at gPhotoshow
The freeware version works really well and displays a carousel of images from a folder for about 10 seconds each. Each monitor gets a different photo.
I'm not affiliated with this at all but wanted to share it with the community.
