The criteria for buying a 4K TV

Screen size

The choice of screen size is often the first criterion for buying a television according to our comparative test. There are now large models of displays at an affordable price.

The most popular screen size, and the one recommended by experts for 4K technology, is the 55-inch dimension. This is indeed the best screen size to take full advantage of 4K technology.

We also advise you to choose the size of your 4K television according to the space you have. Thus, for a 55-inch TV, the recommended setback distance is 2.10 meters.

The type of slab

The choice of the panel partly determines the quality of the image but also the visual comfort. Among the most widely used technologies are LCD and LED. The least expensive technology, but which nevertheless offers very good brightness, is the LCD . For better contrast and a better viewing angle, LED technology will be preferred.


Many televisions now offer features to provide a better experience for users. Among the most present features are: the possibility of connecting other electronic devices, wireless connectivity, integrated applications (such as Netflix or Amazon Prime Video) or even the playback of various external storage media.

We recommend that you opt for a television with at least 2 HDMI ports, ideally a USB port and a digital audio output, at least.

However, it is important to take your needs and habits into account when choosing the best features.


With the growing demand for connected objects, many 4K TVs now have Wi-Fi connectivity, known as SMART TVs. Some even have an operating system similar to your smartphone!

This makes it easy to connect to the Internet and access video streaming applications such as Youtube, Amazon Prime Video or even Netflix in order to fully enjoy 4K content .

Often, 4K TVs come with a voice-activated remote control for easy navigation. Some televisions are even compatible with smart speakers like Google Assistant for example.

Alternatives to a 4K TV

The 4K TV is the best device for watching your programs with an immersive picture quality. The details are indeed very precise, especially in the movements.

However, there are also 8K TVs that take the realism of images to the next level. However, these television models are still not very accessible to individuals and expensive.
