why is my direct stream app via Apple TV only viewable in small window on 4K TV

Hello @mcdanielbrad1, we want to help you to have your service working properly.

Here you can find the compatible devices for DIRECTV STREAM.

Please take a look at it to make sure your Apple 4K TV is compatible with the app. 

Keep us updated with the results.

do you have an updated list of Samsung TV's? this list is only for 2021 as the newest models. my Tv is QN85DA 75" NEO 

Thanks for the heads up @mcdanielbrad1, at the moment this is the up to date compatible devices list. 

You can also use a streaming device as Roku, Fire stick or our DIRECTV STREAM box connected to your TV, until we have an update of the app that includes the 2022 devices compatibility.

I’m having the same issue.  If I am forced to choose between my Apple TV device and DIRECTV Stream it’s a no-brainer on which one is getting replaced - and I’m not looking at Roku or Fire.

I read a post on Reddit from an Apple Tv user---apparently it's an Apple TV glitch https://www.reddit.com/gallery/10yvh30
