A:AnswerYou have to have subscriptions to any of these but Netflix, Hulu, DirectTV Now, Amazon Prime, YouTube, and many other apps come installed on the TV. You can also install any apps that are not preinstalled and you can also access the internet although key entry can be a pain although, most often, you can plug in and use a USB Keyboard instead of the remote--using that is possible if you have an exceptional level of patience. When you chose an app like Netflix, you still have to sign in which means you still have to pay Netflix. The tv will remember your log in data so you only have to sign in once--at least that is the principle. We have had to reset a time or two and resign in.
A:AnswerI had headphones connected to my previous TV. Could not connect them to the new TV - no outlet to plug them into it. Was told I had to get rid of them and get newer updated ones that apparently don't have to plug into the TV.
A:AnswerAn App (on this tv for most else) is a trendy word for "webpage" that allows you to sign into a service like Netflix. It comes with a bunch of others like Directtv Now, Hulu, Amazon Prime, You tube TV (paid subscription), Samsung TV--you can sign up through PayPal (hint, hit, it isn't free), and more. There are some boring, useless, free stations that automatically come on--it plays one as default to annoy you while you attempt to select the app you want. You can also download apps not pre-installed you want. It's clunky, but you can also access the internet.
