A Smart TV has something equivalent to an internal computer, which offers you several possibilities. They allow access to online content, transmitted directly by the television. In some cases, even the interaction between you and the content.Your biggest advantage is to perform these tasks without having to switch between cables and connected components. With the TV remote control, you can access and view any available content.

Have you ever imagined being able to download apps on your TV? Or else talk to the people you care about most through this giant screen? These are just some of the possibilities of a 40 inch Smart TV.

In addition, the technologies integrated into these televisions make it even more enjoyable, like IPTV. A kind of standard for internet videos.

That is, the technology allows internet videos to be transmitted directly to your TV. The options are the most diverse, from short clips to live streams.

Here we make an alert. The access you will usually have is proportional to the price of the TV you want to buy. If you intend to watch platforms like Youtube and Netflix, more affordable models will supply all your interest.

Likewise, the more expensive the device, the more functionality it can have. There are remote controls that accept voice commands to access the content, as well as televisions with intelligence to learn the tastes of each user.

When it comes to features, 40-inch Smart TVs are moving away from any competition on non-Smart TVs.

Another giant leap of separation is called DLNA technology. A 40 ”Smart TV with this function will simply allow you to stream media from computers and smartphones to the TV. Without the need for an intermediary.

Of course, to have these functions, it is not enough to just buy the TV. You need a good internet connection. The kind that runs away from data packets, and quick. After all, you will want to enjoy the best possible picture and sound quality, this will require a lot of data.

The TV can be connected with internet cable (the famous little blue), or even wireless. Each model will provide its options. But here’s a tip: Unless the router is very close to the TV, and be nice, opt for wired connections. They end up providing a much more stable transmission.

In addition, it is common for these smart TVs to have a “home page” that allows you to access available content. And not every Smart TV has the same menu.

It is on this screen that you will have access to practically all the functionalities of the smart part of the TV and will be able to see how well it is able to supply your needs.

In general, smart TVs are made to be very intuitive. Currently, the application options are so many that you can even have a giant karaoke in the living room, or broadcast video calls over the internet.

The result is a more vivid color image, with greater response to changes in light, light and dark. This ends up enlarging the color palette of the TV, showing something very different that an LCD screen would show, for example.

It is clear that, in terms of option, you must choose between LED or OLED. And, to make it easier, let’s set up a table with the main characteristics of each model.

In fact, OLED screens have a large advantage over competitors in the market for a long time. However, they are still relatively new, and with very high prices. LED technology has evolved a lot, creating televisions capable of looking a lot like what OLED can provide.

Resolution

You are daily in front of many screens, and of the most varied sizes. Smartphones, tablets, monitors, televisions, cinema screens, from the smallest to the largest, the important thing is to be able to see what happens in the highest possible resolution.

But, what would resolution be? It is a unit of measurement that indicates how many pixels a screen is capable of reproducing. That is, all screens have small electronic dots inside them that produce color. When stimulated, they convey this in color.

It’s like a math matrix. Columns and rows. So, when you hear that a TV is 1280×720 (HD), it means that it has 1,280 color dots, in width, and 720 color dots in height.

An interesting thing is that the pixels do not have a specific size. This can make the same 40 inch screen support different resolutions. And the greater the number of pixels, the greater the ability to show colors at the same time, enriching the image.

So, what is the best resolution to choose? It is always the biggest. Compare:

Take care, therefore, when speaking only in high definition. Both HD and Full HD are called that, but there is a significant difference in the number of pixels. And it will affect the image quality that can be transmitted.
