When choosing a suitable diagonal of a TV, you need to take into account the distance from it to the viewers' eyes. The resolution of the screen is very important: the larger it is, the shorter the distance to the viewers sitting on the couch can be.
With the advent of large TVs with a diagonal of up to 201 cm on sale, there were more and more people who wanted to purchase such equipment, despite the small area of the apartment and its separate rooms. However, the choice of the diagonal of the TV must be approached with all seriousness and responsibility, because viewing comfort and eye health will directly depend on this.
What to consider first
To choose the appropriate diagonal of the TV, you need to decide on the place where the TV will stand, and calculate the distance from it to the sofa or chair in which you plan to enjoy watching. Accordingly, the larger the diagonal, the greater the distance to the TV should be.
If the total area of the room allows you to install the TV at a distance of only 1 m from a person's eyes, you should choose a diagonal of 14-17 inches or 37-43 cm. For an average diagonal of 26-32 inches or 72-81 cm, you will need to create a distance of 2-2, 5 m. And large equipment with a diagonal of 61-80 inches or 155-210 cm must be viewed from a distance of at least 4-5 m.
Today, one can often hear an incompetent opinion that the optimal distance to the screen is the size of the TV diagonal multiplied by 3. different distances and find the most comfortable for the eyes.
Types of TVs
Today there are three types of TVs on sale: LCD, LED and Plasma. Much depends on the screen resolution - the maximum number of pixels displayed on the screen. High resolution allows you to reduce the distance between the TV and the eyes of people watching it, respectively, this will allow you to choose a technique with a larger diagonal than originally planned. For example, if for comfortable viewing of a 42-inch TV, it needs to be moved 3 m away, then in the case of the Full HD model, you can move 1 m closer to the TV without compromising your comfort.
If you plan to purchase a 3D TV, then high resolution will also significantly reduce the distance between the equipment and the viewer's eyes. So, a TV with a diagonal of 55 inches with a low resolution requires a distance of 4 m, and with a high one - 3, 18 m. This must also be taken into account when choosing a suitable TV diagonal.
