We explain how this new technology that offers more resolution works and we also present some 8K smart TV models. Check out!

Possibly you have heard of smart TV 8K, but do you know what this new technology means? In short, 8K offers the best image resolution available today, offering a more realistic experience than the previous quality, 4K. () Today we will show you a little more about this technology and we will also comment on some models of smart 8K TVs for you to check out.

The technology of 8K

When we say that a smart TV has 8K resolution we are referring to the amount of pixels that she owns. In this case, the smart 8K TVs have 7.680 pixels horizontally and 4.320 pixels vertically, totaling about 33 million pixels on the screen. 8K resolution came to replace another technology that also delivered a lot of competence — and still does today — 4K, and before 4K there were screens with resolution in FHD (Full High-Definition, something like “Completely High Definition”, in free translation).

8K TVs are classified as UHD, that is, these being in “ultra-high definition” containing 4 times more pixels than one smart 4K TV. This means that the image will be reproduced clearer, more detailed and sharper. This is possible because the pixels of these screens are so small that it's hard to tell them apart even when they're very close to the device, and the more condensed, the more realistic the immersion experience. And compared to the FHD, 8K resolution is 16 times higher.

Another curiosity is about the PPI (pixels per inch), since the more pixels there is in an area, there will be even more density of pixels. When the PPI number reaches around 50, the user will be able to enjoy different types of content reproduced by these screens. Having this base, let's check how many PPI there are in each of the following resolutions: FHD, 29 PPI; 4K, 59 PPI and 8K, 117 PPI — assuming these screens are at least 75 inches. The indicator for 75-inch screens is because the larger the screen and the more condensed the pixels, the better you will see the images in 8K.

Should I buy an 8K TV?

Despite the more timid arrival of 8K technology in Brazil, the smart 4K TVs are still a good alternative. In terms of values, for example, the smart 8K TVs are currently priced very similarly to 4K TVs when they first came out. Obviously, some aspects must be taken into account, especially around the technologies offered, that is, the more current the device you intend to buy, the more expensive it will be.

  1. Without native 8K content via Blu-ray or streaming, the use of this very expensive technology, in very large sizes, is no longer attractive at the moment. If they at least offered a passive 3D FullHD image in 8K, it would be very interesting to purchase for those who have an extensive film library in this format. As for the image quality in 8K, there are no demerits to comment on, it's all really magnificent.
