What is a smart TV? Everything you need to know

Nowadays, it’s hard to find a mainstream TV that isn’t smart. Sure, there are a handful of ultra-budget options out there that offer a no-frills viewing experience, but as a general rule of thumb, if it’s on the shelves right now and has either a Full HD or 4K Ultra HD screen, it’s probably smart.

So, what exactly is a smart TV? In a nutshell, it’s any television that can connect to the internet. However, there are varying degrees of smartness: Some TVs ⁠— like the flagship LG C9 OLED — have a much higher IQ (OK, that isn’t an official term, but they’re definitely smarter) than others.

Here’s what you need to know.

What makes a TV smart?

The major feature separating smart TVs and not-so-smart TVs is an internet connection. Nearly all smart TVs come equipped with both an Ethernet port and built-in Wi-Fi — some older models may require an adapter to enable the Wi-Fi functionality — so they should be able to connect from anywhere in your house. Generally speaking, Wi-Fi should be fast enough for most purposes, but if you plan on streaming games or 4K content, you might want to hardwire to your network instead.

An internet connection is primarily used to stream television shows and movies from a variety of apps and services, like Netflix, Hulu, HBO, and YouTube (among others). Occasionally, there will be free stuff available (like on Crackle, Tubi TVPluto TV or the Roku Channel for Roku TVs), but for the most part, you’ll need to subscribe to these services to access their content. Many smart TVs also have web browsers baked in — though these are typically unwieldy and frustrating to navigate — and some even have cameras for use with video-conferencing apps.

All about the apps

A smart TV isn’t very smart if it can’t be used to access a variety of different services, which is why almost all of them come with their own app store. At the moment, Roku OS and Android TV lead the pack with the largest selection of apps. Roku, which refers to its apps as “channels” has thousands to pick from. Most of these are content-focused, with plenty of subcategories like sports, religion, philosophy, automotive, and more. There’s something for everyone. Android TV has these, too, but in fewer quantities; it tends to have more games and utilities. Samsung’s Tizen and LG’s WebOS platforms also have plenty of apps to choose from.

One Rome, many roads

Even though all smart TVs are built with the same goal in mind — helping you access your favorite content without a middleman (in this case, a set-top box or streaming stick) — they don’t all work the same way. In general, each manufacturer uses a different operating system with its own individual features and quirks, though some systems, like Roku TV, are built into TVs from multiple manufacturers. Below is a quick breakdown of the most prevalent systems available.

Operating system

The Lowdown

Samsung Tizen Tizen is extremely fast, and it’ll automatically detect devices that you connect to the TV, labeling inputs accordingly. Plus you can control some connected devices with the TV remote.
LG

WebOS

WebOS is extremely simple and fun to use and may support motion control with the included remote.
Sony Android TV If you use an Android phone, this should be immediately familiar. Sony smart TVs support Google Cast, which lets you project content from your phone (or tablet) onto your TV.
 TCL Roku OS Like Roku streaming boxes, Roku OS is awesome, featuring simple navigation and best-in-class search that looks through every app for your chosen content. There’s even voice search.
Toshiba Amazon Fire TV In addition to the inclusion of the Amazon Video app, you’ll get access to Alexa, a personal assistant to help navigate your TV and control your smart home devices.

Voice search

For the most part, smart TV interfaces are designed to be simple and easy enough for anyone to use without training or tutorials (after all, lots of people check out display TVs before buying). Still, sometimes you just don’t want to hunt and peck — and that’s where voice search comes in.

As a fairly common feature in newer smart TV remotes, voice search turns navigation into an easy, one-click task, no matter what you’re looking for. But be aware that certain platforms — like Roku — offer more robust search tools than others, and remote microphones aren’t always great at understanding your voice, so patience is important.

But what kind of commands can they handle? Here’s a brief look:

  • “Play the latest episode of Lucifer on Netflix.”
  • “Open Amazon Prime Video.”
  • “Switch over to HDMI 3.”
  • “Mute the volume.”
  • “Turn off after this episode of Friends.”

Some higher-end models come with Amazon Alexa or Google Assistant built in, which offer access to a much larger knowledge database. Using one of them, you’ll not only be able to tell the television what to do but also to search the internet for answers to questions and scour through your connected accounts for contextual information, such as calendar events.

If your TV doesn’t come with a voice remote in the box, you may also be able to access voice search via a smartphone app, or by hooking up an Amazon Echo or Google Home.

Alternatives

Not all smart TVs are created equal. Perhaps the TV you like doesn’t have the best operating system, or maybe you just don’t have the cash to pony up hundreds for a shiny new screen. If that sounds all too true, set-top boxes and streaming sticks are great alternatives that offer nearly all the functionality of a high-end smart TV at an affordable price. Roku’s products (such as the Streaming Stick+) do a great job of turning existing dumb TVs into smart ones, as do Google’s Chromecasts and Amazon’s Fire TV devices.
