The demand for higher resolutions and image quality is increasing and growing along with the market for large screen TVs and monitors, making terms such as UHD, 4K and recently, 8K part of the vocabulary of consumers and advertisements. But what is the real advantage? To know if it’s worth investing in such a high resolution, understand what 8K means and the differences between the terms.
The terms Full HD, Ultra HD, 4K and 8K refer to the number of pixels present on the screen during display. The more pixels, the better the image quality, as more media information is displayed in an image space. A pixel is the smallest unit that makes up an image or video and one of the tiny dots present on screens, such as TVs, cell phones or monitors.
What is the difference between 8K and 4K?
The difference is exactly in the number of pixels contained in the image. While in 4K resolution we have 3,840 x 2,160 pixels, which totals 8,294,400 pixels on your screen, in 8K quality we have 7,680 x 4,320 pixels, which displays a total of 33,177,600 pixels on your monitor, that is, exactly four times the previous resolution.
Of course, this automatically makes us think that it is excellent to have this resolution on a TV or monitor, however, is it really worth investing in this technology now?
The content available in 8K is still a little scarcer, although the media are evolving faster and faster and soon we may start to have a greater variety of programming in that resolution, so the advantage will depend on how soon you intend to guarantee a screen that support more advanced image quality.
Another point is to understand that, although it is great to have four times more pixels on the screen when compared to the 4K resolution, this difference is not so visible to the human eye. So, if you are an enthusiast and always want to have the best image quality, it might be interesting to invest in an 8K model. Otherwise, UHD or 4K resolution still delivers an impressive picture with a wide variety of content.
Requirements for playing an 8K image
In addition to the availability of 8K content, keep in mind that you also need equipment, such as TVs and monitors, that support this resolution and, in the case of streaming, a good internet connection. In addition to stability, it is recommended that your speed exceeds 40 Mbps to watch content without stuttering.
Where to find 8K content?
Although we still don’t have 8K content available on a large scale, it is possible to find some possibilities. YouTube already displays videos in this resolution, which makes it a good choice for consuming 8K media. The most well-known streaming services, such as Netflix, Amazon Prime, HBO Max, for example, still do not offer productions with this quality.
Recently, Globoplay showed a chapter of the soap opera Pantanal in 8K, as we show in this matter. But, it is worth mentioning that the content was only available for some Samsung TV models.
The most modern cell phones, since 2020, record content in 8K. Some models like Samsung S20, S21 and S22, as well as other manufacturers, support recording videos with this quality. But, of course, you have to remember that high resolution media takes up a lot of memory space, so any 8K recording, however small, will take up a nice chunk of your device’s storage.
And the upscaling?
To display lower resolution images on higher quality screens, some TVs may perform the upscaling, which is to make an image destined for a screen with fewer pixels to be able to “fit” on a larger screen, without loss of definition. It is important to make it clear that there is no increase in resolution or the amount of information present. It’s just an adaptation to a larger format.
So, now that you know and understand what 8K means, it’s up to you whether it’s worth investing in that resolution or settling for the 4K content we have available.
