All the answers you need to know about 4K TV & UHD

Posted on in News
While 4K Ultra HD televisions are right here, content is still not there.
4K Ultra HD
 
4K, also known as Ultra HD (UHD), just like its former brother HD was a few years ago, has become all anyone in the television business is talking about. 4K Ultra HD offers four times the resolution of traditional HD displays. The answer to this improvement has something to do with the amount of pixels a 4K TV contains. While traditional HD has 1920 columns and 1080 rows of pixels, Ultra HD has a total resolution of 3840 pixels by 2160. However, when you try to buy a new television and you are offered to a 4K TV you realize that there's a lack of 4K content out there.
 
Why did we call it 4K?
The main reason UHD is called 4K is because the images are around 4000 pixels wide. Curiously, the industry used 1080p to refer to HD concerning the image height. Nevertheless, the same industry refers now to UHD with the term 4K regarding the image width. To add further pressure to that, you an also hear people talking about 2160p to refer to 4K. That's true. It can be a bit tricky for outsiders, right?
 
A matter of size 
When we do a little bit of introspection, one realizes that this advance is really similar to the one from SD (480 lines high) to HD (1080 lines high). Only this time 4K screens are already flatscreens and you may not feel the same thrill you did when you changed your old CRT to a flatscreen.
For someone who is not very keen on technology can be challenging to perceive the differences between a HD and a 4K television. Indeed what really makes the difference on a 4K screen is if you're watching 4K content through it and if you're sitting close enough. To really appreciate the difference between these two technologies, we have to make comparisons playing with distances. At a same standard distance between the couch and the television we may probably don't see any differences. However, when you sit closer to a 4K set you realize that the same sized screen fills more of your visual field, so it produces big impact on the viewer. This close-up factor is one of the reasons why 4K computer monitors are a growing successfully emerging sector in the industry.
 
What's the next step?
8K is the next resolution standard up from 4K. It basically offers the double pixel height and width again to grant about 32 million pixels. Unfortunately, 8K standard is not ready for the public yet. It's only available for the exhibition market as we have been seeing it in the recently past conventions Vector 3 has attended all over the world.
 
Can I watch 4K content?
There is not much 4K broadcast content to be watched on your television right now, unless you buy a 4K UHD Blu-ray player and a few 4K Blu-ray discs. Broadcasting TV in 4K is still not implemented because 4K content is four times bulkier than regular HD content in terms of file size. And that's for sure going to be the challenge everyone in the television industry will be talking about in the near future. Onb the other hand, there are the online streaming services such as Netflix, Sony or Amazon that offers some 4K UHD films, series and TV shows to the public. They are services on demand that depends on your internet's bandwidth. Nowadays seems not reasonable unless you have a very fast internet connection because 4K requires at least 25Mbps or faster downstream internet connection, which is quite faster than most people have right now.

So, if you can't wait to experience 4K at home, you know now that 4K televisions are here and they can be your present. On the other hand, if you're worried about how much it'd cost or what content options do you have right now, you'd probably wait until 4K sets go cheaper and the content side of the equation is a bit more solved. Don't worry, sure it won't take long.
