Bluetooth Smart TV's

Nope. You still have to connect the TV to your cable source.

Since you are streaming, you already have a smart TV that should be able to play video files. A simple way is to put your video files on a small USB drive and plug it into your smart TV which should be able play them using some built-in app. If you are more tech savvy, you can set up media streaming server software like Plex on your computer. Then you can stream through your own media files over your wifi network to your smart TV. This is very useful when your computer and your TV are in different parts of the house. Some TV models offer Bluetooth for connecting headphones/speakers but it is not an ubiquitous feature, so you have to make sure before you buy.

You can easily cast from your computer to your TV with a Chromecast or similar device. And of course Plex, as R2 suggested. I use that to watch my porn that's stored on my desktop downstairs in my bedroom.

I just got a Chromecast so I can broadcast from my phone to the tv. My tv is about 10 years old and didn't have wifi.

Be careful of the ones that can be "upgraded" by the manufacturer without your consent like Samsung for instance which installed tracking software on their TVs.

R1 is mistaken. I live in an older house and wanted to keep cable TV when I moved in, but there wasn't anywhere to run coaxial cable to the TV itself, given its location in the room (not near a window or any wall through which cable could be strewn). It took a fair amount of trial and error, but I finally figured out a wireless router that would let me plug the cable adjacent to its entry point into my house, and then stream the signal over in-house wifi.

Aside from that: OP, I have a Bluetooth-enabled home theater system with speakers connected wirelessly to my TV. There's no getting around using power cords for everything, however.

R5, unless you're watching literally nothing other than over-the-air TV – meaning HD antennas, and having neither cable TV or streaming services – *someone* is always "tracking" what you watch. Netflix, Apple, Amazon, Google, Hulu, Sling, Disney: they all keep detailed records, albeit nominally anonymized, of every subscriber's viewing habits, which they use to both target advertising (assuming a service isn't ad-free) as well as programming.

As an example: Netflix's algorithms can display over 100 different featured icons for any given show or movie, selected on the basis of what it (the algorithm) "thinks" will prove most alluring to you. If you watch a love of gay-themed programming, you'll most likely get an icon even for non-gay stuff featuring a hot actor who's in it – even if he's only a minor character.

Depending on what you watch you may be able to get by using the tv built inapps and a chromecast or other stick to mirror a laptop/tablet/phone screen onto your tv. Some old style “cable” companies in select cities let you watch old style cable channels on an app you can put on the tv. So it really depemds on what you watch, where you live,and how complicated you can handle. Good luck.

Chromecast or Apple TV?

I wish Smart TVs had web browsers. I have the Netflix and Prime along with the free options out there. But I have been using Sling and am absolutely NOT watching it beyond the couple of local networks for news and MSNBC. I have tried numerous antennas without luck. I guess I will have to hook a laptop up to the TV - it would just be easier if the browser was built into the TV. But Sling costs almost $50/month...

I think there's a web browser on the Amazon Fire devices.

We have Apple TV and an Apple laptop and somehow my BF has on a few occasions been able to take something he was playing on the laptop and play it on the TV.

I have a web browser on my Samsung Smart TV.

Thanks, you beautiful Lounge people! I discovered that my TV is actually wirelessly getting signal from my WiFi modem/router which is connected to a coaxial cable wire (nephew set it up for me while I was recovering from surgery. Hadn't had a TV for >15 years. He had to show me how to use the remote). I guess that must be the definition of a "Smart TV"? Just ordered a Chromecast gizmoid after finding out WTF it is. Now to figure out if my TV can pair with bluetooth speakers or if my laptop will broadcast sounds from programs.
