Is there a way to add/upload my own pic's/photos for my X1 platform TV screensaver - rather than the landscape/animals selection?
Yes, kind of, you won't be uploading pics but accessing them from social media accounts (Facebook or Instagram).
Xfinity button to Gear Symbol to Screen Saver to Screen Saver type and press OK, choose Personal Screen Saver. Choose the user, it will show Primary user and any secondary accounts that you have set up. Choose Facebook or Instagram and then how you want to customize.
Make sure your account is linked to access Facebook, Instagram or Flickr through
