Do you know of any 1920 TV that has a card reader and built-in slideshow software?

In my son's Samsung 4K TV, there are slots for memory sticks (USB) and when I plug the USB loaded with jpg files, there is functions to run a slide show.

Do you know of any 1920 TV (preferrable under 36") that has the same USB slot and function?

My 24" Vizio from 2010 can do that.

I am trying to use a larger monitor (TV) as a digital picture frame to display my pictures. Someone on the other forum reminded me that I have Apple-TV and I can run the slideshow from my iPhone or iPad and display the pictures on my TV. I think that's the route I am going go.

Just one issue, the connection of the iPhone to Apple-TV seems to drop off by itself. Any suggestion to make it more continuous?
