In recent decades, television and related technologies have undergone significant changes, especially with regard to image quality. Regarding the latter, the technology that has been most optimized is the resolution. It has gone from the lowest resolutions such as SDTV or VGA, to HD and Full HD, up to the recent Best 4K TV, also known as Ultra HD.

This type of resolution allows the transmission of very clear and well-defined images. In addition, along with the improvement of the quality of the resolution, new technologies have been introduced such as, for example,HDR, which is able to offer further optimized frames. The latest generation televisions rely on these two technologies, which guarantee a high level of home entertainment.

So let’s see, specifically, what the UHD 4K offers, how it differs from its Full HD predecessor and where you can enjoy content with this resolution.

What is 4K and what benefits it offers

Best 4K TV, also known as Ultra HD, is the new generation in the field of image and video resolution. This technology possesses a number of pixels equal to 3840×2160, that is, four times the previous resolution. The visual rendering is of high quality, thanks to a sharpness and an incomparable realism.

The depth and variety of the color gamut are also optimized, to offer extremely realistic content. In fact, televisions with this resolution, have a reduced level of image distortion. This also applies to very close distances, which makes them an excellent solution even for confined environments.

4K and Full HD: here are the differences

The differences between Full HD and Ultra HD basically concern the quality of the projected images. First of all, it must be said that Full HD resolution can be defined as a sort of evolution of HD: the latter, now almost in disuse, could reach a maximum definition of 1280×720.

To be categorized as Full HD, TVs must have a resolution of 1920×1080 pixels, respectively the number of pixels placed horizontally and vertically. Pixels are handled as each frame passes, but the speed of this operation reaches, at most, 24 frames per second. This speed is equivalent to that of photographic film.

Images projected in FHD possess a good level of detail, and the images look realistic. The color gamut offered by FHD TVs is fairly wide and vivid: the colors are bright and well defined. Despite the good characteristics of the FHD, in recent years the Best 4K TV Ultra HD resolution is taking hold, that is, the latest generation technology.

The main motivation is the rendering of the images, which turn out to be of high quality thanks to the accuracy of the details. The color range offered by this resolution is extremely realistic, nothing to do with that offered by Full HD. The popularity of TVs with 4K resolution is mainly given by the excellent quality-price ratio:they are slightly more expensive than full HD ones but they meet the viewing needs of consumers much better.

However, despite its notoriety and excellent performance, the number of 4K content broadcast by traditional television is still quite small. In this regard you could think of buying a Best 4K TV as an investment for the not too distant future.

4K and HDR: the perfect mix for ultra-realistic content

The introduction of HDR in audio and video content took place at the same time as the birth of Ultra HD resolution. Nowadays, the latest generation of top-of-the-range TVs combine 4K resolution with HDR. But what specifically is this technology, and what improvements does it bring?

First of all, the acronym HDR stands for High Dynamic Range and defines a technology that can maximize image quality. There are four areas of images optimized by this technology. First of all, the resolution is involved in a positive way: the images appear very accurate, detailed and, above all, realistic. An additional benefit is found in the depth of color.

Depth is the maximum number of shades of gray or colors that a pixel can take on: the more colors a single pixel takes on, the greater the depth of the transmitted content. HDR also helps to improve the quality of colors and shades: whites appear bright and bright, and blacks dark and intense.

The brightness of the frames also suffers positive effects, as HDR widens the dynamic range between the darkest and brightest points of the scenes. The gloss of the image is then perceived in a very natural way, and the darkest or lightest areas will be able to show even the smallest details. There are currently four HDR standards:

  • Dolby Vision: it offers a brightness that is not static, but variable from scene to scene or, even, from frame to frame;
  • HDR10 Media Profile: possesses a fixed brightness from the beginning to the end of the content. This feature is a limitation for such technology compared to Dolby Vision;
  • HDR10+: formulated to overcome the aforementioned problem, this technology combines static brightness with dynamic brightness. For this version, the maximum achievable brightness of 4000 nits has also been improved;
  • HLG: acronym for Hybrid Log Gamma is the HDR standard developed for television content, be it satellite, digital terrestrial or live broadcasts.

Where to find content in UHD 4K

Although Best 4K TV UHD content is widespread, traditional channels are a bit sparse. Most movies or TV series in fact, only go up to Full HD resolution. To enjoy this resolution it is necessary to connect to various entertainment platforms, and take advantage of a fast and stable connection. The best known platforms for this type of products are Netflix, Amazon Prime Video, Infinity, but also Youtube, Sky and many others.

The only flaw is the obligation to subscribe ,sometimes even premium, to be able to watch movies and series in Ultra HD. In many cases though, the price is very affordable. This is the case of Netflix which, by activating the Premium subscription, gives the possibility to view content in 4K from four devices at the same time.

For optimal viewing in Ultra HD, Netflix recommends a band of 25 Mbit/s; if this is lower, there may be interruptions or a reduction in the quality of the content. As for Infinity, accessibility to 4K content is only possible if you own a TV equipped with a special feature, or through game consoles.

For high resolution on Sky instead, you need a subscription to SkyQ (with SkyHD funzonalità). Despite this, Sky’s 4K offering is one of the richest on the market, as it offers movies, TV series, documentaries and sporting events. As far as free Best 4K TV is concerned, there are satellite channels, such as Rai 4K or 4K1, accessible through the free tivùsat platform. On Youtube, on the other hand, thousands of videos and playlists are available in Ultra HD.

Ultimately, being the maximum resolution on the market, to be able to access it is not enough to turn on the television. At the moment we have to resort to these platforms, which try to respond to the needs of consumers.

HDMI cable and 4K televisions

To make the most of Best 4K TV content you must have a special HDMI 2.0cable. An HDMI 1.4 cable will therefore not be enough, as it does not reach the minimum standard of data transmission speed. For this type of cables, the speed it supports reaches a maximum of 8.16 Gb/s, perfect for Full HD resolution, but insufficient for 4K content.

Later, in 2013, HDMI 2.0 cables were introduced, exponentially faster than the old generation cables. The most recent ones reach a speed of 18 Gbit/s. This standard is indispensable for viewing videos and movies in 4k Ultra HD and, if the TV is equipped with it, also for HDR.

The best HDMI 2.0 cables are those equipped with a 4K badge, which ensures that it has been certified as a Premium HDMI Cable Certification Program. These cables are able to offer the highest Best 4K TV quality, as they are tested on the ability to handle the standard of 18Gbps of bandwidth. The quality of the cable makes the difference in environments where the viewer is at a great distance from the TV.

In conclusion, why choose 4K?

In recent years the resolution of televisions has been significantly improved, and to date we can enjoy television content with a cinema quality. Thanks to 4K, the projected images appear extremely accurate and detailed, ensuring an excellent visual experience and maximum involvement.

The realism of the frames is accentuated, as is the color gamut. Along with 4K, HDRtechnology has also been developed, which gives images extreme depth and brightness. All these positive features are also found in television programs, both live and not, thanks to HLG, or HDR created specifically for television broadcasts.

There is no shortage of 4K content and, if you do not find it to your liking on traditional TV, you can make use of the platforms currently available. In conclusion, in the coming years we will certainly see a further development of Ultra HD resolution, which will be present in most televisions and will represent the starting standard.
