Selecting the diagonal value of the TV is far from being such a simple task as it may seem. For some people, a small compact device is quite suitable to watch your favorite programs, and other viewers need a huge wall-to-wall TV that will amaze the pomposity and scope of the equipment purchased. With this approach, unforeseen problems associated with an unsuccessful choice can arise. If you do not take into account the equilibrium distance between the diagonal size of the TV receiver and the screen of the device, then a situation may arise in which the image of the image will be fuzzy and blurred. As a result, the joy of buying is lost, and the money invested is in vain. In this article, we will look at how to correctly determine the distance from the TV, depending on the diagonal.

Basic knowledge of the diagonal

In the modern market, there is a huge variety of models with all possible dimensions, sizes and design. That's why before you buy a device to watch interesting programs, you need to decide which room it will be in, because:

  • in a small room is not very convenient to watch TV with a large display;
  • in the living rooms and reception rooms are the perfect solution to become a plasma.

Important! If the size of the room is insufficient for the selected TV-receiver and its diagonal is very large, then a variant of the screen image may be blurry or the image may skew. Sometimes there are cases of the appearance of incomprehensible "squares" that interfere with a clear picture of the image. All these inconveniences are caused by the wrong choice of the screen for watching TV.

If you do not adhere to certain recommendations, you may experience problems with health, in particular, an increase in the negative impact on vision.

The diagonal line is the length diagonally between the two corners of the screen. Measure this distance in inches. The value of one inch is equal to 2.54 centimeters. From the size of the diagonal depends the distance to the TV from which you want to view the desired programs and movies.

Selecting the diagonal of the TV based on the distance to its viewing position

There are two principles by which you can determine the maximum display diagonal:

  • The shortest distance from the viewer to the TV receiver's display should be at least five diagonals of the TV screen. This is a simpler method for determining a parameter.
  • For more accurate size of the TV-device, you can use the following formula: D = L / K, where:
    • D - the diagonal of the TV-receiver display, expressed in inches;
    • L - length of distance to the diagonal screen;
    • K is a factor used in the range from 3-6, which is taken into account when calculating the minimum and maximum distance values.

Important! In standard small TVs, the display diagonal is about 15-18 inches, and in this case the smallest distance from which it is acceptable to watch the TV receiver is 1.5 meters.

When choosing a model with a large diagonal - 70-80 inches, the minimum allowable length to the screen of the device is 5 meters.

Standard parameters

In order not to engage in mathematical calculations of calculating the diagonal length of the TV-receiver for viewing TV programs, you can use the already created table with preliminary calculations of the necessary parameters. The list below shows the display diagonal relationship to the optimal viewing range for viewing:

  • 14 inches( 37 cm) - distance to the TV from 1,2 to 2,2 m;
  • 20( 51) - 1.4-3.0 m;
  • 21( 54) - 1,8-3,2 m;
  • 26( 64) - 2,0-3,5 m;
  • 29( 73) - 2.2-3.8 m;
  • 32( 81) - 2.5-5.0 m;
  • 34( 87) - 2.7-5.3 m;
  • 36( 92) - 2,8-5,6 m.

Important! There are manufacturers who, in the provided characteristics, only indicate the visible part of the screen. And some manufacturers are trying to calculate the diagonal parameter of the TV receiver, based on the size of the whole kinescope. However, this is an insignificant difference, since it does not particularly affect the final decision of choosing a TV model to watch your favorite shows.

Diagonal to screen resolution ratio

In addition, the length of the distance for comfortable viewing of the TV receiver depends not only on the diagonal, but also on the quality of the picture shown. The diagonal size should be comparable with the resolution.

The most popular are two format resolutions:

  1. HD Ready with 1366 * 768 pixels.
  2. Full HD with 1920 * 1080 points.

Important! The image quality depends on the number of dots or pixels available in this TV device. If a lot of points are involved in the formation of an image, then a smaller distance is necessary for a quality viewing of interesting programs and films on the screen.

The quality of the image depends also on the resolution of the video signal that is input to the input device of the TV receiver.

The list below shows the diagonal parameters that take into account the resolution format and the distance between the viewing point and the TV receiver display.

Resolution format HD Ready:

  • 20-27 inches - the distance from the TV is 1.5-2.1;
  • 37-40 - 2,8-3,0 m;
  • 42-47 - 3,2-3,6 m;
  • 52 - 4.0 m.

Full HD resolution format:

  • 20-27 inches - 1,1-1,5 m;
  • 37-40 - 2,0-3,0 m;
  • 42-47 - 2,3-2,5 m;
  • 52 - 2,8 m.

What else is considered when choosing a diagonal?

In order to determine the required screen size, you need to understand two factors:

  • the dimensions of the room, because this affects the distance to the TV and the viewing angle;
  • main characteristics of the TV receiver's display, such as type and resolution.

Important! The larger the diagonal, the more expensive the TV, because manufacturers spend much more money to make it. Also, the diagonal size affects the weight, the thickness of the TV receiver.

It is considered erroneous to claim that the quality of the image depends on the display size. This parameter has nothing to do with the diagonal of the display. In fact, the picture quality is affected by:

  • blue screen format;
  • display resolution;
  • contrast ratio;
  • quality matrix.

Important! It is more convenient to watch programs on a TV receiver with a larger diagonal, since the eyes do not need to strain much. If the distance to the TV is much less than necessary, the viewing angle increases. As a result, the eyes are very difficult to cover the entire perimeter of the large display, so they get tired very quickly.

Angle of view and diagonal

Correctly selected diagonal, resolution, viewing angle and distance to the display will help feel like a participant in the event and create the effect of presence. This will help to more clearly perceive the picture and feel part of something big.

In order to create a cinematic reality, you need to remember such viewing angle values:

  • 20 ° - to achieve this viewing angle, multiply the display diagonal by 2.5 and get the distance value.
  • 30 ° - in this case the distance is determined by the factor 1.6.This option is considered the most optimal for home theater.
  • 40 ° - to determine the distance you need to apply a factor of 1.2.This is the minimum value for Full HD TVs.

Now produce models with a three-dimensional viewing angle, for which you need to use special glasses. In this case, one should follow the recommendations of manufacturers, but still it is worth giving preference to widely used display options.

Important! In 3D models of TV receivers, the viewing angle should be as large as possible to get a more effective image, but the distance to the TV should be chosen as small as possible.

Variety of displays

For selection of the most convenient and practical TV-receiver it is necessary to consider a number of basic factors:

  • type of model;
  • basic resolution formats;
  • the distance from the point of view to the screen;
  • display diagonal.

When choosing the model of the TV-receiver, the technological process of manufacturing the screen is also taken into account. Each technology is characterized by a certain size, image quality, contrast, clarity - all these parameters are taken into account when purchasing.

In the modern market, the following manufacturing technologies are presented:

  • TV receivers with a kinescope. These are very old models, the distinguishing feature of which is the presence of large dimensions and impressive weight. TV receivers with a kinescope have a very long service life. They are more reliable and durable in application in comparison with liquid crystal and plasma models. However, devices with a kinescope as a screen image are very inadequate.
  • TV receivers with liquid crystal display. Particularly recognized and generally available models for viewing the broadcasts. LCD TVs have an excellent imaging effect. They can be produced in small sizes, which is very convenient for small rooms. When operating LCD TVs, sometimes there are difficult situations, since the viewing angle does not always correspond to the kinematic reality. In addition, there may be problems with the clarity and contrast of the image. Therefore, you need to very accurately determine the distance to the TV, depending on the diagonal.
  • TV receivers with a plasma display. These are comparatively new models that appeared after LCD TVs. Firms-manufacturers, taking into account the demand and supply of broad masses of the population, make such models of huge sizes. Some models can occupy the entire wall in the home.

Important! Note that a screen with a diagonal value of less than fifty inches can not accept the FULL HD resolution format.

The individually thought-out approach to choosing a TV set is able to deliver immense pleasure from the purchased purchase, combining the price, quality and efficiency of use. So:

  • when viewing the LCD TV screen - you need a smaller distance from which you can watch TV shows;
  • for a plasma panel with exactly the same diagonal length will require a significantly greater distance between the viewer and the screen.

Features of furnishing in the apartment

Before choosing a TV-receiver it is necessary to determine not only the dimensions of the room, but also to understand in which particular foreshortening of the room it will take its place.

Universal system for any room

As we noted above - the length of the distance to the TV from the viewer's location is ideally five diagonals of the screen. This is a very easy and efficient method of selecting a TV receiver. Such a system of choice has common rules, but each person has his own preferences and each has a different perception and value judgment. In addition, visual acuity is also an individual feature, therefore it is necessary to approach the choice of the TV-receiver model independently.

Important! When buying a TV, try as much as possible in the store to test the selected product for a quality image of the picture. To do this, try to consider the screen from a distance that will be used in a home environment.

Possible negative consequences of wrong choice of the location of TV

Given the balance of balance between the distance from the viewing point to the location of the TV, you can avoid negative moments:

  • there is no appreciable load on the vision;
  • there is a pleasant and comfortable state when viewing;
  • there is a clear image of the screen image without any interference.

Bedroom

The installation of the TV in the bedroom depends on the size and dimensions of the bed. Having settled back and relaxed from the hard day, with an instant view of the wall, you can fix a place where it will be most convenient to watch TV.

Important! The height at which the TV in the bedroom is suspended will be relatively higher than the installation point in the living room.

It is necessary to adhere strictly to the recommendations of doctors. The deviation of the angle from the center point of the screen during viewing should not exceed thirty degrees. You also need to clearly determine the distance from the TV, depending on the diagonal.

Important! Failure to comply with the medical advice leads to osteochondrosis of the spine of the neck. Such a problem arises from the prolonged viewing of films and transmissions at abnormal location of the head, respectively - of the neck.

Preferably use high-quality brackets that are capable of adjusting the screen. Correction can be carried out, not only by changing the inclined angle of the monitor, but also by turning the screen to the other side.

Living room:

  • When choosing the location of TV in the living room, it is necessary to take into account the preferences of each member of the family, since basically all their free time the occupants spend in this room.
  • In addition, you need to determine the viewing of the gear will occur in a sitting position on chairs or lying on the couch.
  • Usually the height from the floor on which the TV is placed varies between 0.7 meters and 1.35 meters.

Important! If the living room has very large dimensions, then it is necessary to install a television device at the minimum allowable distance from the floor surface, because in this way the difference in the growth of spectators located on upholstered furniture and small children playing on the carpet is smoothed out.

Kitchen

To determine the most preferred location of the TV in the kitchen you need to know:

  • room dimensions;
  • the distance from the often host zone to the intended location of the TV.

Choose the place and method of installation:

  • If you have small children, you should take care of safety measures and attach the TV-receiver at the maximum permissible distance from the floor.
  • For small kitchens, the possible level of the location of the TV receiver from the floor surface is 1.75 meters.
  • In addition, it is necessary to use reliable mounting brackets to adjust the viewing angle.

Important! With prolonged viewing, it is possible to heat the TV cabinet. Therefore, it is not recommended to place the TV device inside the furniture.

For qualitative and long-term use, it is necessary to ventilate the room airspace.

Now you know everything in order to choose the optimal distance of the TV, depending on the diagonal, its type, the purpose of the room and other, no less important, parameters. So - now you can really enjoy the picture on the screen as much as you want.
