Buyer Guide to Choose 4k Tvs

Size and Inches

Smart televisions are very versatile and represent suitable devices to enjoy quality images in domestic environments. The size of a TV reflects much more than aesthetic preferences.

It is necessary to choose the model paying attention to the position of the TV about the distance to the observation point. From a design point of view, TVs boast refined lines, which reduce the space of the frame for an even more elegant look.

The latest generation televisions such as 4K increasingly become a window on the outside world, increasing the perception of reality of what is being observed. In this sense, minimal and precious finishes help, often in glass or metal.

Resolution and Hdr

As far as resolution is concerned, 4K offers spectacular image clarity and perfection. A 4K screen has a resolution of 4096 × 2160, a relationship initially originated in the cinema sector, and which today, thanks to the continuous development of technology and the increasingly cheaper cost, is also available for home devices.

A 4K screen is in all respects synonymous with Ultra HD: it follows that the video images are of extraordinary sharpness and color precision.

In the case of OLED televisions, the pixels have a bright surface that can emit light autonomously, contrasting with dark colors deeper. The best 4K models have also equipped with HDR ( High Dynamic Range ) technology, which reflects an extremely dynamic range concept.

If, on the one hand, UltraHD increases the number of pixels, HDR increases the quality of each of them and is fundamental for being able to grasp the details of an image with certain light conditions, such as twilight.

The HDR technology aims to reflect the human eye’s ability to grasp the nuances even on the television screen: images visible on a television HDR will return, therefore a spectrum of hues and rich and spectacular shades.

Flat or Curved Screen

The best smart TVs are available with both flat and curved screens. To choose wisely between the two, it is necessary to evaluate their characteristics carefully.

Let’s take a look at the curved panel designed to respond to the need to optimize vision, i.e., the central area of ​​the screen, at a maximum angle of 20 degrees, a value beyond which the video quality begins to be affected.

In flat panels, however, the visual performance is not maximized on the corners. However, this may not always be necessary. To choose between the two versions, one crucial factor must be considered, the desired positioning of the television.

To a lesser extent, also the aesthetic aspect can play a role: the curved screen is more particular and allows you to concentrate a lot of attention on the television, converting the appliance into a real design element.

On the contrary, the flat screen solution involves a slight saving and is preferable when there is no light beam behind.

Connectivity and Ports

The best 4K smart TVs are mainly equipped with an internet connection, which works either via the classic cable for the local Ethernet network or in WiFi mode.

They offer a perfect solution for those who want to access streaming platforms directly from the TV. On these models, there are at least two USB ports and two HDMI: this allows you to increase the possibility of customizing the experience, increasing its functionality.


Smart televisions that mount very high-resolution screens often do not find adequate innovation in the audio sector, which, although excellent, is certainly penalized compared to the spectacular video definition.

For those who want to build a home entertainment system of the highest level, you can consider purchasing a Home Theater system, which allows you to obtain sounds very similar to those of a cinema.

Alternatively, you can opt for a soundbar, a more convenient option from an economic point of view, and also very simple to handle.

Operating System

Among the most popular brands, LG mounts the famous WebOS operating system, with particularly sharp and captivating graphics. In contrast, Samsung, another very popular choice among the brands of televisions, opts for Tizen, which stands out for its functionality and high usability.

Sony instead chooses the excellent Android TV: this operating system for smart TV is undoubtedly the easiest to manage and also update.

That’s why most of the high definition smart TVs choose Android as an alternative option compared to WebOS, which defends itself and is still very valid.

Led or Oled: Which to Choose

The OLED technology differs from the LED or LCD for the fact of being able to issue in standalone mode a light source. Smart TVs that mount a panel with OLED technology, whose acronym stands for Organic Light Emitting Diode, an expression that indicates the presence of an organic diode, are certainly more innovative than the LEDs on the market.

In OLED screens, the pixels are made up of a special organic material that lights up when it receives electrical impulses: it is this aspect that effectively makes the backlighting that is necessary in the case of LED technology superfluous.

This results in the greater brilliance of some colors, such as black, which is considered pure and reproduced when the pixels are completely turned off, giving rise to a well-defined contrast and dramatic images.

Watching a movie with an OLED smart TV brings a higher-level experience. However, among the disadvantages of the OLED, we find the fact that, by the presence of organic material, the screen has a much shorter duration than the LED version.

The latter, in particular in the QLED version, exploits the Quantum Dot technology, which provides for the presence of many conductive nanocrystals capable of reproducing the light in a much purer way than the classic LEDs.

In essence, OLED panels are certainly preferable about angular vision and image quality. However, QLEDs are competitive in terms of price, an aspect that cannot be overlooked.
