Don't buy a smart TV. I did and it's a waste of money. Just get Apple TV or Chromecast or something like that.
Not all TVs are smart, it's becoming more and more common, but it's still not 100%. Perhaps that store only sold smart models. I wouldn't get too caught up with smart TV though, especially on the lower end brands/models as the offerings tend to be very limited, and you will get better from a cheap add-on box that can sit behind the TV....
LED or LCD which better quality?
I have a Toshiba flatscreen...sorry no idea if it is LED or LCD. I have to connect my laptop to the TV if I want to watch Netflix or anything else online....It is a bit of a pain because generally when I'm watching TV I'm working on my laptop. So was very interested in getting a smart TV . What is the difference between a smart TV and an Apple TV?
