Choosing TV is difficult: dozens of manufacturers, ranges and rare names to name the improvements in image quality that come to the new models every year. The key features, interestingly, are often hidden. As if that were not enough, on large surfaces it is impossible to observe the advantages of each TV due to the configurations used with the brightness, contrast and color almost to the maximum. 

General concepts 

it is best to start choosing a TV ignoring all names removed from marketing departments and specification sheets: the relevant information is always in the background to give prominence to news that rarely benefit the image quality TV. 

The next step is to choose an appropriate size. Normally, the limit is set by the living room furniture. The bigger the TV, the better. When counting 4K we should not be afraid to see the blurred image if we sit close, but quite the opposite: we appreciate all the details better and we will enjoy an experience more similar to that of the cinema. Sony recommends that you sit at a distance of 1.5 times the height of the TV to view 4K content (approximately 1 meter distance for 55 "models and 1.2 meters for 65" models). 

Forget about the operating system and the "smart functions" of the TV is another good idea when choosing a TV. With so many inexpensive devices available such as Google's Chromecast or the new Apple TV 4K, narrowing the purchase options can be a mistake. In addition, few manufacturers offer a good experience. 

Image quality 

• Choosing the maximum image quality according to the budget we have in mind is the main objective when purchasing a new television. There are several guidelines that can always be followed: 

• OLED TVs have the best image quality for their perfect contrast, which is the most important feature on a TV, how they manage and show moving images and their color range. 

• The LED screens incorporate an external light that illuminates the pixels preventing the black from being black. But they are cheaper televisions and they do not have certain problems that may occur, occasionally, OLED TVs, like the burned-out image. 

• LED TVs that have local dimming offer better contrast in dark scenes. 

• A well-calibrated television often looks better than a more expensive, poorly calibrated TV. 

For gamers 

If the new television is going to be connected to a console, it is important to choose a model that does not have a long delay between the signal and its sample. It is commonly known as "input lag": the less time, the better. It is important to put the TV in Game or "Game" mode because it deactivates the additional filters that worsen the response. Everything that is less than 30 milliseconds will be optimal, except for first-person shooter enthusiasts who will need a monitor. 

Is it worth the OLED technology? 

OLED televisions are almost always more expensive than LCD LEDs because manufacturing them is a more expensive and, above all, delicate process. However, their perfect blacks and their perfect contrast will delight the moviegoers and those who stay behind watching series on Netflix and the like. If you are going to see many series and movies at night, and your pocket allows it, OLED TVs are unmatched. Companies like Samsung prefer to keep betting on the LED, and continue to improve the maximum brightness, the minimum and the contrast of the panels. But the difference still exists and OLED TVs are becoming more and more affordable.
