But the key is to do some research before purchasing your next smart TV. To help, we made a very simple and easy-to-understand comparison, with the main differences between the types of televisions on the market today. We also explain how to choose. Let’s check it out?

What are the types of TV technology today?

Increasingly larger and thinner, the televisions we know and use are classified by their image resolution. The idea is this: the higher this resolution, the greater the number of pixels on the monitor — those tiny dots that together make up the image on the screen, you know?

The more pixels your TV has, the better your experience will be when watching your favorite channels. Easy so far, right? It turns out that technology has allowed for an increasingly real and detailed image . This explains the evolution of types of TVs HD, Full HD, 4k etc. Now you will finally understand the difference between them!


Also called High Definition — hence HD 😉 — this high definition resolution was very successful when the first plasma, LCD and LED screens hit the market. After all, this is a screen with almost 1 million pixels (1280 x 720 px) . For those who were used to tube television, it was a giant leap!

Despite being the lowest resolution currently, this type of TV delivers an excellent picture. She’s really good at watching open channels , paid channels or that good old DVD of yours, you know? It is also worth remembering that it is common to find HD on smaller screens.

Full HD TV

Here, the business has already started to improve. Not that HD is bad, far from it! But Full HD resolution brings much more pixels and even better image quality. We’re talking 1920 x 1080 px here . She is the darling of the market and is already part of the homes of many Brazilians (from Minas Gerais, too).

Affectionately seen around as FHD , this television is a good choice for those who want a product with better definition and with an affordable price. With it, streaming catalogs — such as Netflix, Amazon Prime and Disney+ — and online games gain a top-of-the-screen experience. 🔝

Ultra HD TV

If Full HD was already good, just imagine the Ultra HD, which has nothing more, nothing less than 4 times more pixels ! Its screen has a resolution of 3840 x 2160 px and monitors are usually from 50 inches.

The larger the screen, the greater the richness of detail. It’s a very realistic image, ok? It’s like you’re seeing it all live. Too cool! And this type of TV is also known as UHD or 4K .


Well, if you thought there was a difference, we are talking about the same thing! The famous 4K television is the Ultra HD resolution. The “K” in the International System of Units (most common outside Brazil) represents the number 1,000. Just do the math now! 🧮

It turns out that, in addition to the 3840 x 2160 px resolution, we also have the 4096 x 2160 px resolution. A lot, right? But this format is mostly used by big companies in the film industry. However, with the speed of technological transformation and popularization, we cannot doubt that this, perhaps, is the future of our televisions.

By the way, we already have 8K and 10K resolutions out there, you know? The business will not stop there!

Smart TV: HD, Full HD, 4K and Ultra HD... Which is the best option to buy?

HD, Full HD, 4K or Ultra HD TV: how to choose yours?

Now that you know the main types of screens for your television, you may be wondering which is the best. At 4K, right? Well, in terms of image quality, it is! Without a doubt.

But that’s not all you should consider when choosing your television. HD and Full HD TVs are still widely used and have a satisfactory picture quality, both on TVs and on cell phones, notebooks and tablets. They are currently the most sold on the market, for the sake of price and compatibility. 💰

As well? Well, you need to consider that 4K TV carries some drawbacks that will only be resolved when the format becomes really popular among users. Here are some:

  • the amount of content currently produced in 4K is still small;
  • 4K broadcasts require a much faster internet connection;
  • open TV in Brazil still does not show any programs in 4K;
  • streaming subscriptions (like Netflix, the most popular of them) tend to charge a little more for 4K content;
  • speaking of Netflix, even if you have the plan with 4K content, you need a faster internet connection to be able to watch without those famous travadinhas.

Did you see? The latest technology is not always the best option at the moment . Therefore, you need to study your needs, the reality of your home, your internet plan or package, and then buy the product that will serve you in the best way.
