    Smart TV Buying Guide

    February 11, 2021

    Our use of televisions has changed radically in recent years. Nowadays a TV is used for much more than to watch ‘traditional’ TV, it is the multimedia centre of the home from which to consume content on-demand, play with your video game console, browse your photos or if you are a Movistar Fusion customer and With the UHD Decoder, enjoy a world of digital consumer experiences through Living Apps.

    Smart TV

    However, not all smart TVs have the same features or offer the same experience. Therefore, when choosing the best TV for our home, we must look for the resolution and technologies that offer the best experience.

    Main features: choose the best Smart TV


    When taking a photo with the Smartphone and zooming in, we can see the importance of resolution. As we get closer, we notice some small and blurry points of colour, better known as pixels. The more pixels that accumulate in space, the sharper and more realistic the image.

    Until recently televisions (HDTVs) reached a peak of 1080p (1920 horizontal pixels and 1080 vertical pixels) delivering a total of 2 million pixels.

    They may seem like enough, but as TVs have gotten bigger, pixelation can become apparent.

    Currently, Smart TV Ultra HD (also known as 4k) deliver a resolution of 3840 x 2160 pixels (2060p), totalling 8 million pixels. Now, the first commercial models with 8k are starting to arrive, but they are still limited to the more premium ranges and usually only in large formats.

    TV size

    4K technology is finally allowing us to offer large formats while maintaining very high levels of sharpness. TV manufacturers already offer options ranging from 32 “to 100” and since televisions are already very thin and aesthetic, you can bring home a totally immersive experience in which the screen fills your entire field of vision, almost as if you were in the cinema.

    Of course, it is useless to choose the best TV on the market if it doesn’t really suit our space. For TVs with FullHD resolution, it is normally recommended to calculate the ideal size as follows:

    TV Buying Guide

    Measure the number of inches from the viewing location to the screen.

    Divide it by two, and this is the ideal number of inches.
    That is, for a distance of about 2.5 m it is recommended not to exceed a size of 50 ”for a FullHD TV. From that size or at a lesser distance from the TV, the sharpness would begin to deteriorate.

    But with the arrival of 4K (4 times more pixels), everything changes and at the same distance of 2.5m, the industry estimates that an 80 ”4K TV would still be seen optimally. In any case, we recommend visiting our other article in which we explain how far away to watch a 4K television.

    How to transform measurements from inches to centimetres on televisions?

    The first thing to keep in mind is that the size of a television screen is measured diagonally and not from corner to corner. That said, the transformation of measurements from inches to centimetres on televisions is very simple:

    1 inch = 2.54 centimeters.
    Thus, a 50 ”TV would be 127 cm diagonally.
    Panel type (LED – OLED)

    The screen of an LED television is illuminated through a set of light-emitting diodes, better known as LED lights. On the other hand, a TV with an OLED (organic LED) panel uses a slightly different technology. In this case, each pixel generates its own light, where each zone can be completely turned off and achieve perfect blacks.

    In short, an LED TV delivers grayish blacks and OLED perfect blacks. However, a traditional LED tends to be brighter and maybe better for places with lots of natural light.

    HDMI ports

    It is also crucial to pay attention to the number of HDMI ports a Smart TV has (the more the better). With just adding a Home Cinema, a decoder and a video game console, we already have three ports occupied.

    Preferably they are compatible with HDMI 2.0 to reproduce Ultra HD content.


    HDR is a new feature that is being integrated into LED / OLED televisions and that stands for High Dynamic Range (High Dynamic Range in Spanish). The objective is to present the colours more faithfully, achieving more spectacular results, with higher levels of contrast and precision in the brightness of the screen.

    The contents that support this type of technology are based on standards such as HDR10 or Dolby Vision, and although they are not as widespread yet, they are starting to gain in popularity. They are normally characterized by better recovering the information in the less illuminated areas and more nuances in the more vibrant areas, so if you want to ensure optimal image quality in the future, we believe it is important that your TV supports it.
