Sometimes when the slideshow shows the next photo it takes the TV a couple moments to download and decode the image. This shows up as an initially black screen, and then photo either pops in a little later or it keeps showing up in chunks.
In my case the connection between the Jellyfin server and the TV is wired, to the limitation here is entirely just the interface speed of the TV. I also acknowledge that the processor in the TV might not be the fastest, so I should not expect it to be able to decode the larger photos super quickly.
However this is just as much of a problem on the regular web and people have come up with some solutions to mitigate the jank in these scenarios. In particular by trying to load and decode one or two photos ahead and before the photo currently displayed. That way, by the time user gets to the photo, the photo will be available for immediate presentation in pretty much every situation.
