My idea is, under the regular tab for posters on a show, if you have an account linked to a fire tv there will be something called like Fire Tv Poster or something but, it would be the poster for your show that would appear on the fire tv home screen
I’m not exactly sure what you’re suggesting…
Do you want content linked to your Fire TV account to be displaying inside the Plex app or content from your Plex libraries to be displaying on the Fire TV home screen?
… or something entirely different? Maybe you could elaborate this a bit more?
The second option. Being able to open my shows on Plex through the Fire TV home screen would be a great addition. More specifically on the edit page for shows there’s a bar that says Poster. If you have logged into Plex through a Fire TV, it would add a tab under Poster saying Fire TV Poster, and that would be the poster that appears on the Fire TV Homepage, for your show.
I still don’t understand…
Why do you want a separate poster to show on the Android TV / FireTV Home Screen?
I mean, on Hulu when you watch a show, if you leave Hulu it would appear on the home screen/ you could ask to watch it with an Alexa. Being able to do that with plex would be nice.
Do you mean you want Plex to act as a „source“ for the Android TV start page, so content from Continue Watching are showing there accordingly?
IIRC you should already be able to do that… however I cannot currently verify this. At some point I got annoyed by every app spamming the Home Screen, so I disabled „something“ (and now I no longer remember).
On my rather dated Sony Android TV there’s an option in the TV settings where you can enable/disable installed apps as sources (System > Start Page > Sources).
I still don’t get why you want to assign a separate poster for items inside Plex for that purpose… 
I don’t believe you can do this on the Fire TV. There’s no such configuration on the model I have anyway.
You can however do this on other devices like the Shield or like Tom said for his TV
That leads me to believe this is not a Plex limitation. If this does work with things like Hulu, I suspect they gave Jeff Bezos a pile of money
Because I thought that was the only way you could do that sort of thing. Because on the Fire TV, shows on the homepage have horizontal posters not upwards posters. But if it’s not then OK. And yes, that is what I mean tom80H. OH and just so you know, I was talking about the shows on my server. Not the free stuff. Because that stuff does appear.
No, It is a Plex limitation, because Plex already does this for its free TV. At least on my model. And that’s actually why I got the idea for the recently watched, because I was talking about my personal media.
I can populate the Fire TV with live TV from my Youtube TV subscription too. That means Amazon allows this for live TV. I don’t think Youtube is the one dictating these terms to Amazon either
If the setting for this is inside Tom’s TV that means Sony is the one in control of what it allows it’s customers to populate their home screen with. Not Plex
An Amazon home screen is essentially a billboard so Amazon can sell people things. It makes sense to me that they wouldn’t let Plex or any 3rd party dictate what their customers see. This essentially pushes a revenue stream away from the eyes of a targeted demographic
You seem to have come to a conclusion I wouldn’t reach until I had more information
