On most Rokus that I have, the path to the screensaver is
Settings -> Theme -> Screensaver
I have one Roku TV with Software 12.5.5 Build 4174-48. This has some significant differences.
Settings -> Wallpapers & screensavers
The wallpapers & screensavers area is quite unique and I am unable to set a screensaver that I have downloaded.
I have included a screenshot![20240502_133133.jpg 20240502_133133.jpg](https://community.roku.com/t5/image/serverpage/image-id/16373iC3E14D8DBD60CFE4/image-size/large/is-moderation-mode/true?v=v2&px=999)
