  • low power consumption;
  • slim body;
  • wide selection of diagonals;
  • increased service life;

Smart TV technology provides an Internet connection for accessing applications and broadcasting various content. In this case, it is more convenient to use a smartphone as a control, if the TV has such an opportunity.

3D support

3D technologies are active and passive. Active provide high image quality without additional software settings, which affects the cost of the receiver in the direction of appreciation. Passive are convenient to use and easier to manufacture, so models with them are cheaper.

Advanced 3D TVs have the following features:

  1. PiP technology - picture in picture.
  2. Translation of a flat image into a three-dimensional one.
  3. Controlling the depth of a three-dimensional image.
