Characteristics of TVs. Description, comparison, what to consider when choosing

When choosing a modern TV, it is recommended to pay attention to the technical specifications. There are many TV sets on the market, you can get lost when choosing the right model. Manufacturers go on tricks, for less than one price they sell less quality models. With all the stated possibilities, it is recommended to inspect the picture in stores, because the subjective opinion of buyers is ambiguous. Sometimes the same screen is perceived by visitors differently.

The main technical features of flat TV

The characteristics of televisions are often indicated on a limited list, the consultants allocate only profitable items in terms of sales. The manufacturer makes a revision of the appearance without changing the previous capabilities of the internal "iron". And sellers put TV as a technically improved version. However, by examining the Internet, you can easily identify the catch.

Let's highlight the main characteristics of TVs, which are important for the buyer:

• Screen: brightness, resolution, diagonal, shape.
• Sound: volume, number of speakers, software enhancements.
• Ease of use of the menu, the control panel, compatibility with gadgets.
• Additional features: connection to the Internet via cable or Wi-Fi, built-in decoders.
• Economy, ways to adjust the brightness: automatically or manually.
• Thickness, weight, appearance of the purchased device.

Problems of choice

For all the listed properties of the TV, incomplete information is provided for the purchase of the device. If the buyer chose LG TV, the price may be much lower when looking at the next model. The maximum set of functions for the average cost can rarely be found.

The characteristics of TVs are skillfully varied by manufacturers, forcing buyers to take halved devices without Wi-Fi, but with an updated version of the console or a curved screen with a low-power processor. Additional functions are useful, but it is not advisable to sacrifice basic parameters for them.

Professional approach

Technical characteristics of TVs are often presented in a favorable light for the buyer. Many people confuse the screen resolution of 1920 p and 720 p, which is virtually impossible to distinguish externally in the store.

Select the parameters specified in the device's passport:

• The pixel response;
• Viewing angle;
• Color rendition;
• Type of matrix;
• Way to illuminate the picture;
• The ability to transmit 3D images.

The characteristics of LCD TVs are selected under the conditions of use. If the room does not have sunlight, a superbright LED screen does not need to be purchased. Even the powerful radiators can not cope with daylight.

In the electronics market LG TV is offered, the price of which is lower than that of competitors with similar characteristics. It is equipped with a screen built on quantum dots. The image is transmitted with realistic colors, the picture does not fade in the sunlight.

Extra options

Experienced users pay attention to the number of interfaces. Type of connection with peripheral devices: USB, COM-port, VGA, HDMI-connectors. The image quality is affected by the integrated graphics processor, which can be selected from the test tables provided on the Internet.

USB connections are divided by the speed of reading the version: 2.0 or 3.0. The latest models have a convenient SMART control menu, some top-end TVs perform voice commands and gestures of the owner. To avoid distortion of dynamic pictures, developers supply the TV with a special mode. This becomes actual when you connect a set-top box or watch sports channels.

Convenient integration in new TV

Manufacturers complete the model with functions:

• 3D-effect provides watching movies at home in a volumetric format. New TVs no longer require the use of special glasses;
• Smart TV is an integrated environment for receiving a signal from the Internet. The program shell expands the list of channels, allowing to use almost any resource of television of the whole world. It is not necessary to pull a separate cable of the provider, which significantly reduces the price of monthly maintenance. It will take Internet LAN or Wi-Fi, and it is already in every house.
• 4K is four times the resolution of FullHD, which allows you to view video from professional cameras.

Power and type of radiator

Plasma screens have brightness indicators lower than LCD and LED-TVs. Prices and characteristics previously prevailed in the first type of TV, but over time, new technologies took up. However, the plasma still transmits more saturated colors by using a discharge directly at the luminescence point.

LED-TVs are equipped with emitters, providing a light output of up to 500 cd / m * 2. The backlighting of pixels requires the presence of a powerful lamp behind the screen, located at the bottom in the center in a single copy or in a two-row arrangement. The latest TV models are equipped with bright diodes, eliminating the effect of color loss when changing the viewing angle.

Comparison of models

The light source of the LCD models is a powerful lamp, hence the small viewing angle and brightness. The characteristics of LED-TVs are enhanced by the use of bright diodes. Plasma screens are expensive, but have increased contrast. Saturation with colors is obtained by the technology of image reproduction: the glow is formed not by a lamp, but by a discharge at each point.

The characteristics of LED TVs are close to plasma ones. The latest models have a small weight, a large screen diagonal. Curved screen versions are designed to provide the viewer with a picture without spatial distortion. Advantages of LED are: a thin layer of pixels, high brightness, low weight electronics.

These movie fans choose plasma TVs, the characteristic of which is a high-quality image, saturation and minimum pixel response time. But for good dynamics and review, the owners pay with shortcomings:

• Gradual burning out of the screen, the service life is calculated on 30.000 hours, that on the average about 9 years of daily viewing of cinema;
• Large mass of the device;
• Increased energy consumption.

The plasma panel has advantages when watching a movie in a dark room, black tones are more expressive than LCD TVs.

Pixel response and resolution

Competitive models are capable of reproducing small details of a picture and saving contours of dynamic images. Such features have plasma and LED TVs. Characteristics, description are given in the passport of the device. It is recommended to read the documentation before purchase.

Users noted the pattern: similar screen parameters for different manufacturers do not guarantee that the picture will be played in the same way. This feature is noticeable when two TV sets are placed side by side and turned on to full brightness. This is due to manufacturing technology and subjective perception of the human visual organ.

The response time affects the image of moving objects, very small details are clearly discernible at a resolution of 4K. This characteristic of TV screens appeared on Asian models. But manufacturers promise to implement such screens on all future TV.

The widespread standard of digital broadcasting in Russia DVB-T2. For satellite TV - DVB-S2, but to receive the signal of the last format, prefixes-decoders are often used. Broadcasting of news programs and many TV shows is conducted with a resolution of 720 by 576 points.

The purchase of high-priced and high-resolution, high-resolution models only for viewing evening shows is comparable to the purchase of an all-terrain jeep for city driving. If it concerns prestige, then there is some sense. From the point of view of the layman, the rationale for choosing televisions is rational saving of money.

Angle of View and Contrast

Budget LCD screens have significant drawbacks. If the viewing point is incorrectly selected, the geometric size of the images is distorted and the color of the picture changes. In many ways, it depends on the technology of converting the digital signal into visible light: plasma, LED indication, LCD panel.

The contrast parameter is important. It is impossible to provide absolutely black pixel any technology presented. Neighboring glowing dots give the gray link a broken link. This characteristic is indicated by the relation between black and white colors. The larger the gap, the more natural the transmission.

What can you save on?

When choosing costly multifunctional equipment, it is recommended to take into account the peculiarities of television broadcasting standards. It is not advisable to buy the 4K-resolution function if the TV is intended for watching HDTV programs. Buyers often overpay for managing Smart TV, but do not use the Internet.

A similar situation occurs with the 3D function. According to the results of a partial poll, mature customers watched the video of this format several times after the purchase. The cheap option is interesting for young people and children. The following options are available for controlling the TV:

• Manual from the buttons on the front panel of the device;
• Using the remote control - the most practical method of switching channels;
• Voice - the novelty increases the cost of the TV;
• Gestures - a rare option that also affects the price of TV.

The quality of the image should not be saved, because the new TV is purchased in order to improve the transfer of realistic objects. A natural picture is obtained with the help of new technology UHD - quantum dots, transmitting natural colors with high contrast.
