If you are reading this, you are probably aware that a 55 inch 4K Smart TV can make your favorite content even more enjoyable.

A 55 inch TV with premium smart features and Dolby sound is what you need if you are thinking of switching to a new TV set for your bedroom.

But, even though there is no dearth of excellent 55 inch TVs out there, the high number of options will always confuse you.

This is where we will help you. In this article, we are reviewing (after extensive research) one of the best 55 inch TVs LG has to offer.

So, buckle up if you want to get yourself informed before you can invest in this smart TV. The article will also help you understand the basic technology working behind what is delivered to you in today’s advanced TVs.

If you want a quick answer, this TV offers great picture quality, the sound performance is impressive, and you get convenient smart features with a voice-control option. But, it’s expensive and the dark parts of the images may appear a little too dark.

For those interested in knowing more, let’s get right into the details now. First, we will uncover some technological terms (in plain English) to educate you about the stuff you should know before buying.

4K Ultra-High Definition

Ultra-high-definition is another term for 4K resolution, for the layman at least. You most probably have enjoyed the 1080p resolution in the recent past or currently own one.

The display technology has advanced so much in recent years that the display resolution we used to love back then isn’t a big deal now.

New and improved display technologies like 4K resolution have hit the market, significantly enhancing your visual experience.

The more the pixel count, the more detail can your TV display deliver. 1080p resolution has a total pixel count of 1920 x 1080p. 4K is four times that. This means 4 times more detail, which significantly enhances the realistic nature of your content.

So, if you have the budget for a 4K resolution smart TV, not going for it would be a mistake. Especially, if you spend a good amount of time-consuming online content.

High-Dynamic Range

High dynamic range is just an improvement in the standard dynamic range technology. The technology takes on the contrast of a TV display and improves it for more lifelike imagery.

The improved contrast allows you to see darker darks (while retaining clarity) and brighter brights. This way, you can enjoy your favorite movies and TV shows with more contrast and detail.

OLED (Organic Light Emitting Diode) Technology

Organic Light Emitting Diode technology uses thin films composed of organic molecules that produce their light.

These molecules produce their light when electricity is applied across them. The resulting display is crispy and bright, even more than a typical LED or LCD.

Plus, OLED is energy-efficient. It consumes lesser energy than its counterparts, making it the best thing you could invest in.

Not only that, OLED delivers better color, higher refresh rate, better viewing angle, higher contrast, and brightness.

Moreover, the design of these OLED TVs is slim and the body light. These displays are even foldable and flexible, making them a thing of the future.

Freeview Play

Freeview Play is an online TV channel platform that lets you watch more than 70 channels on your smart TV.

Most of them aren’t delivered to you in high definition, but some are. 15 of these 70 channels are HD, making the service worth having. After all, it’s just adding to your content consumption options.

Energy Class A

Energy Class A is simply a rating given to TVs based on their energy-efficiency. Energy Class B rating lies below it; meaning that a TV with an Energy Class A rating saves more electricity than a TV with an Energy Class B rating.

As the name suggests, the energy saved while delivering smart features and 4k display cuts down on your electricity bills in the long run. Which makes that smart TV a cost saver and worth the initial investment.

Dolby Vision and Dolby Atmos

Dolby Vision and Dolby Atmos are technologies that enhance your viewing and listening experience, respectively.

With Dolby Vision, your display is improved for a more realistic experience, while Dolby Atmos enhances the sound by making it more immersive and lifelike.

So, if you don’t want to connect a soundbar with your TV, having Dolby Atmos will suffice for your audio needs.

LG ThinQ

LG’s ThinQ is an artificial intelligence platform that lets you interact with your TV using your voice through a virtual assistant.

For instance, you can control your LG TV using just your voice through Amazon Alexa or Google Assistant. ThinQ also lets you interact with other devices, but the condition is, the devices must be compatible with the platform.

In short, it’s just an AI technology working to make your interaction with the TV as convenient as possible.

LG Magic Remote

LG magic remote’s sole purpose is to make your navigation hassle-free and time-efficient. So that you can focus on the content rather than searching for it.

The remote has a simplistic design and allows you to navigate, search, change the channel, and interact with the TV using your voice or, of course, the buttons.

Display Performance

If you have reached so far, you have read the OLED technology part of this article. You understand it’s a technology that’s here to stay.

In addition to providing crisp, detailed, lifelike images, OLED TVs save on your electricity bills big time. They consume less energy to deliver premium features and stunning pictures.

This 55 inch 4K Smart TV’s OLED technology not only makes the visuals amazing, but it also allows the makers to produce a very thin display. So much so that you can bend the body of this TV. It’s flexible and will look great on the wall.

Plus, high dynamic range and Dolby Vision improves the contrast and detail and 4K resolution delivers extreme detail in your content.

However, the dark parts of the images may appear a little too dark.

Overall, a great combination of technologies working together to deliver an immersive visual experience to you.

Sound Performance

You will not find many TVs in the market that can satisfy an audiophile. The straightforward solution to this is hooking up a soundbar through the HDMI port or the optical port of your TV.

However, it shouldn’t be the case if you are trusting a product with hefty upfront investment. Thankfully, some brands realize that and put enough technology into sound performance.

This 55 inch 4K Smart TV’s great sound performance can be attributed to Dolby Atmos. It’s an audio format that improves the quality and delivery of the sound, making it immersive.

So, if you are eying a soundbar even before buying this 55 inch 4K Smart TV, there is probably no need. First, try the inherent sound system, you can always get a sound system of your choice at a later time.

Smart Features

Smart features are the backbone of any “smart” TV. You don’t want a slow user-interface and little content consumption options online when you are putting in your bucks.

An operating system is just a medium to interact with the TV. A fast interface and user-friendly navigation are what you need on your TV for a good overall experience.

LG uses a smart TV operating system that’s particular to the brand. WebOS allows you to interact and control this 55 inch TV and navigate through the menu smoothly.

However, the TV is a little costly. So, it will require an upfront investment.


As far as connectivity options are concerned, the 55 inch 4K Smart TV has Bluetooth connectivity and 4 HDMI ports.

The availability of HDMI ports on any TV means you can attach your external devices through one cable without losing any data. You can stream and play high-quality content by just hooking up your devices via an HDMI input.
