> I don't want to go back to the Frame's software

It’s not really a viable option if you wanted to. I have two Frames and they both just keep deteriorating to the point they are pretty useless. I have added an appletv to one of them and it’s vastly improved the UX. Now the only thing I need to do with the Samsung software is the unreasonably slow task of switching inputs.

A dumb TV you can buy for cheap on Facebook Marketplace or Craigslist with an Nvidia Shield or a similar streaming device running Android.
