  • Scanning frequency?;
  • 3D technology?;
  • The smart TV offer?;
  • Energy consumption?;
  • Ergonomics.

The size of a TV matters a lot when making a purchase.You have to take into account the size or configuration of the room that will accommodate the television.It feels cramped when the TV is too big for the bedroom.Likewise, a small TV is not ideal for a large living room.For an Ultra HD TV, it is recommended to have a viewing distance of 1.3 times the diagonal of the screen.To put it simply, if the screen size is between 46 and inches, the reversing distance should be between 1.5 and 2 meters.As a reminder, the size of the TV diagonals is in inches, and 1 inch is equal to 2.54 cm.Despite its details, the size of a TV also depends on the use you want to make of it.Many people enjoy large screens in order to better enjoy the pleasure they offer.As for the panel technology, it is essential in the video quality of a screen. Today, televisions are equipped with different technologies: LED, Edge LED, Direct (Full) LED, OLED… Plasma and LCD screens have shown their limits and are increasingly rare.

LED technology

The majority of televisions embed this technology.It is a backlighting system for the screen which is carried out using diodes (LED or Light-Emitting Diode).These replace the neon lights on LCD screens.Regarding Edge LED technology, the diodes are placed at the periphery of the screen.Unlike the Direct LED whose diodes are located behind the image in a uniform manner.We recognize certain strengths in LED technology:

  • Enhanced contrast?;
  • Bright colors?;
  • Wide viewing angle?;
  • Low power consumption.

OLED technology

In an OLED TV, each pixel is made up of a diode. And, each diode emits its own light. This makes a single screen made up of an almost infinite number of LEDs.There are many advantages:

  • Excellent image quality?;
  • Exceptional brightness?;
  • Infinite contrast.

Ergonomics and price

Is the television suitable for my needs? Does the remote have any advanced features? Which operating system (Android, WebOS, and Tizen) is right for me? All of these considerations can influence a customer's choice.Added to this, the quality of the TV interface is as important as the design and thinness of the screen.In short, ergonomics take user comfort into account.Finally, your budget will condition the purchase of the TV.

Other criteria for buying a 4K TV

The fluidity of videos depends on one criterion: the scanning frequency or refresh rate.This is the number of images displayed per second on the screen.For example, a 50 Hertz (Hz) television displays 50 frames per second.The higher the frequency, the smoother the video.3D technology brings relief perception from 2D images.Glasses are therefore essential for this technology.Brands offer active glasses and passive glasses for their 4K TVs. Regarding the Smart TV offer, it offers the possibility of connecting to the net from your TV. It also allows you to access YouTube or streaming sites. Reduce the amount of the electricity bill is imperative for many consumers.That's why you have to choose a television that consumes little energy.This is a criterion that many people overlook, because they are focused on other elements.More and more, manufacturers are taking care to mark the power consumption on devices.
