1080p or 4K. is there a tangible difference?
I’m pretty sure that everyone who reads the title of this article answered mentally: Well, of course there is a difference! And he will be absolutely right: there is a real difference! over, recently YouTube began to support UltraHD videos. But is this difference really significant and is it worth buying a monitor or TV with 4K resolution, which are currently asking for a lot of money??
- Ultra-HD Blu-ray players and discs will not appear until late 2015. Then it will take at least another couple of years for the amount of available (including the price!) 4K content to have a good selection. So far, only a limited number of videos in UHD quality can be downloaded from Sony Pictures via several types of Sony Pictures media players.
- Microsoft Xbox One and Sony Playstation 4 both have 4K hardware support, however, none of THESE platforms have the power to render 4K video games. Sony PlayStation 3 can only display photos in UHD resolution. there is no question of any video.
- A limited number of providers abroad already provide some content with 4K resolution when using their set-top boxes, but the streaming quality leaves much to be desired because there is a high degree of stream compression. Acceptable 4K online So far, nothing more than a dream. In our country, the Internet can barely cope with FullHD playback, and at 4K speeds we can only dream 🙂
Do I need 4K and is it worth buying TVS with such a screen? To summarize, it is safe to say that as long as you do NOT start looking closely at TVs with a diagonal close to 100 inches or more, 4K resolution will be absolutely useless for you and not worth the money spent. 1080p displays are more than enough for everyday home use today.

4K and Ultra HD. advantages and comparison with Full HD
The terms Ultra HD and 4K are widely used in the next generation TVs and game consoles. What do they mean? Is there a significant difference between Ultra HD and 4K? Let’s consider this issue in more detail. I would like to note right away that there are no noticeable differences between these terms, but 4K. professional standard and Ultra HD (UHD). it is a consumer label common in digital broadcasting.
From the point of view of modern definitions, an Ultra HD TV should display a resolution NOT lower than 3840 by 2160 pixels, having at least 8 million active points. However, 4K resolution varies up to 4096 by 3112, depending on the manufacturer’s standards and digital content. Total pixels and aspect ratio vary.
The Consumer Electronics Association (CEA) originally labeled the new tech as 4K, but the Ultra HD sticker is now more common on TVs. The resolution is formed by increasing the vertical and horizontal pixels by 2 times (compared to Full HD 1080P, which at the time of its appearance was also a high-definition television standard).
What is the Difference Between 4K and 1080P Resolution?
In general, the Ultra HD picture will have 4x higher resolution than 1080P. Various codecs allow you to Compress 4K content for viewing and storage at home. If you use uncompressed formats, each movie will weigh tens of terabytes! To watch 4K on the Internet online, you need a gigabit connection.
When transmitting a signal from a device to a TV, a regular HDMI cable will not work, but you must use the HDMI 1.4 port, which is equipped with almost all modern media players. The result is broadcasting the signal at speeds up to 30 FPS. Looking for 60 FPS? Check out the models that support HDMI 2.0. Today, such a port is not common, but over time it will become the standard for various types of multimedia devices.
While the difference between 720P and 1080P may seem imperceptible on small TVs, 4K content will be significantly better than Full HD when viewed on a compatible TV. And on the desktop of a personal computer, the difference is noticeable to the naked eye. The larger the diagonal of your TV, the more obvious the choice in favor of Ultra HD. With a matrix made using Retina technology (for example, it is used in Apple laptops and tablets), the picture in 4K looks absolutely fantastic!
What 4K content is available for watching on TV screen?
The most varied. The first films in Ultra HD began to appear only in 2012, but over the past 7 years, their range has reached thousands of titles. First piece. the famous Timescapes documentary showcasing Mesmerizing landscapes with a spectacular night sky. The cost of movies in iTunes varies by 5-10 times, depending on whether you choose Full HD or 4K. The first option will always cost the viewer less. For example, 9 versus 99.
Today the Largest Media Networks are also looking towards Ultra HD. For example, Netflix, which is producing House of Cards TV series and a number of high-definition documentaries. The minimum connection speed to view Netflix begins 4K at 25 megabits per second, that there is not in every home. However, in the EU and the US, this problem is not as urgent as in Eastern Europe. Sony also makes 4K media players, but you must have a Corresponding TV to watch them, so the pleasure cannot be called cheap.
Many film studios in 2016-2017 began to steadily produce 4K-movie version, so the range is constantly growing. There are also hit films of the past, obtained using remastering or simple stretching of pixels (in this case, 4K will not give an increase in image quality). If you would like to shoot video in 4K, and even at 60 FPS, you have to look towards professional cameras. They are not just expensive, but very expensive!
Does it make sense to move to 4K?
Currently, there is no boom in 4K TVs, because this technique remains available only to the enthusiast, willing to pay extra for the opportunity to try out all the latest technologies. The answer is simple: no, I don’t recommend switching to 4K yet. Wait a few years for the standard to gain proper acceptance. Over time, manufacturers will start offering more affordable TV and media player options. This was the case at one time with both Full HD and 2K.
Another advantage of 4K is the active advancement of 3D cinematography. Previously, glasses were required to watch a movie in 3D, and the image remained grainy and NOT too comfortable. Now, with the introduction of Ultra HD, this “feature” has become widespread. Especially in cinemas and parks, where special booths are installed for watching short and effective videos.
Today, 4K resolution, in addition to geeks and enthusiasts, is preferred by professional designers, photographers, video editing and 3D rendering specialists. It is important for these people to have at hand a technique “for growth”, which does NOT lose its relevance for many years.
Among consumer technology, it is worth noting models of TVs from LG and Sony, as well as the Xbox One X console, recently presented by Microsoft, which provides full 4K output at up to 60 FPS. Summing up, this technology has enormous potential, which will be revealed in the coming years.
Now, it makes sense to take such a technique for content creators who strive to offer their viewers material of the highest quality, comparing favorably with analogues, as well as to all those who want to join innovative technologies.
