Hello and welcome to Apple Support Communities Mayorofvail,
I see that you're having an issue with your screen saver photos being blurry. I can understand wanting to have this issue resolved, and I'd be happy to help.
Let's have you check a couple of things. First, are the photos pulling or being used from your own photos in the Photos app? If so, let's have you try to use a default collection that is already on your Mac, like Landscape or Flowers and test to see if the issue remains.
If the issue remains, try resetting the SMC (system management controller) on your Mac and then testing again. If needed, the steps are listed in the article below.
How to reset the SMC of your Mac
If the issue remains after trying these steps, reach back out.
Thank you for using Apple Support Communities.
