And the use of TVs based on liquid crystal panels provides for a more careful attitude than other varieties of similar technology.
Which diagonal is better to choose?
As a rule, almost any buyer looks at large TVs. Before making a final choice, you should carefully analyze several important points:
- room area;
- model type;
- specific TV location;

In a large room, a large TV will look best. The minimum screen size must be at least 26 inches.
In addition, a lot depends on the resolution of the monitor. The larger it is, the better the image quality. For example, even when you get close to the screen, you don't see the "graininess" of the picture.

- 61-80 inches diagonal is best used for space over 4-5 meters;
- distance 2-2, 5 m will be optimal for TVs 26-32 inches;
- if you watch TV at a distance of up to 2 meters, you should choose a smaller screen.
