Which smart TV has the most features?

It's easy to look for the smart TV with the best display panel or the loudest speakers, but those aren’t necessarily classified as operation features. Sure, better visuals are always welcome, but you might be disappointed if it lacks “true” features. For example, an 86-inch OLED system won’t do you any good if it doesn’t have any HDMI ports or speaker connections.

With that in mind, there is a checklist you can use to determine which TV is best suited for you. 

In this article: LG 75-Inch Class UQ9000 Series Alexa Built-in 4K Smart TV, Samsung 55-Inch Class Crystal 4K UHD Smart TV and Amazon Fire TV 75-Inch Omni Series 4K UHD Smart TV.

Features to consider

Remember that the TV with the most features isn’t always the right one, and you need to be sure that you’ll at least use most of them for the TV to be worth your money. Still, there are many features that go into a great smart TV, though which ones you’ll need depends on your setup.


Starting with the basics, consider how many external devices you have that need to connect to the TV. HDMI is the most common input source and is used by all video game consoles, home theater systems and streaming devices. If you don’t want to swap cables around when changing the source, look for a TV that has the same amount of HDMI ports as you have devices.

That’s the hardware side of things, but software also contributes to quality. Many smart TVs feature high dynamic range, which improves the contrast between very dark and light areas on the screen. Taking that a step further, some high-end TVs feature Dolby Vision, which adds greater depth, contrast and more colors to content.

You might seek out a 4K TV that uses these features, but it doesn’t have to be limited to 4K content. A great additional feature to have is upscaling. The software manipulates any content that’s at a lower resolution and fills in the pixel gaps to upscale it to 4K. This lets you enjoy any films or videos at a much higher quality.


Coupled with the visuals, the audio can play a huge role in your enjoyment. The default speakers on large TV are usually good-enough quality for watching sports or general TV shows. However, when it comes to blockbuster films and video games, they aren’t sufficient. 

The best solution for this is to look for a TV with an optical audio connection that lets you attach an external speaker source. Tacking on to that, a TV with built-in Bluetooth allows you to stream the audio to any wireless speaker.

But hardware isn’t the only solution to better audio. A great feature to have on a smart TV is Dolby Atmos. It uses the AC-3 lossless audio format to create a theatrical experience by adding height channels, letting sounds be interpreted as three-dimensional objects. In addition to hearing the action horizontally all around you, it creates audio that sounds like it's coming from above or below you.

Connectivity and streaming

It’s a shame when you have a technologically advanced TV and nothing to watch. But manufacturers have thought about that too, and more models now have built-in Wi-Fi receivers. This lets the TV connect to the internet so you can access most streaming apps.

The best feature to have is an intuitive interface that makes browsing and navigation easy. Most smart TVs use an Android-based operating system, an app store and a remote controller capable of voice recognition. This integrates with virtual assistants like Amazon’s Alexa and Google Home, letting you automate other things in your home through your TV, such as lights or cameras.
