What to look for
Comfortable reception with a television panel with Smart-TV functions depend on:
- screen size;
- authorization;
- viewing angles;
- frequency sweep;
- type matrix.
For full enjoyment of your receiver box with this technology need a reliable internet. Also, it should be possible to read different formats, software with user friendly interface and the transfer of 3D images.
Screen size
Among the variety has a model with the smaller 17 inch displays to the panels on the wall. It is a question of the buyer preferences and size of the room in which it is established TV device. For the normal perception of the distance from the screen to the viewer should be three times the diagonal of the TV. In a small city apartment or an ordinary private house does not always have as much space. Therefore, pre-calculate the floor area under the plasma.
Resolution
This characteristic is measured by the number of pixels and affects the clarity and detail of the image. The more, the better the image, it is easier and more comfortable perception. The optimal resolution for your TV at home - HD with the expansion of 1280x720 or Full HD 1920x1080 with extension. Both formats are used on television.
Size, image quality and the distance to the TV
| The distance (in meters) | Diagonal (in inches) | |
|---|---|---|
| Full HD | HD Ready | |
| 1,1 – 1,5 | 1,5 – 2,1 | 20 – 27 |
| 2,0 – 2,2 | 2,8 – 3,0 | 37 – 40 |
| 2,3 – 2,5 | 3,2 – 3,6 | 42 – 47 |
| 2,8 | 4,0 | 52 |
viewing angle
Until recently, the unpleasant feature was a narrow flat panel review, because of what the picture is distorted. To image is easily visible from any point, the viewing angle should be as broad as possible and ideally reach 180 °.
frequency sweep
A particularly important indicator for the flat panel TV device without CRT. The minimum frequency of 50-100 Hz makes it impossible to view the picture, because the screen flickers objects move jerkily, broken image integrity. To avoid these defects need to select the display at a frequency of 200-400 Hz.
type matrix
There are TVs with such matrices: LCD (LCD), plasma, and LED. They have different imaging technologies and different prices.
A popular option available - devices matrix LCDWhich gives a good picture and a large viewing angle. But these models are not resistant to physical influences.
plasma televisions stronger. They have better color reproduction, but they are more expensive, consume more energy and burn more quickly.
Smart-TV c LED matrix the best compromise option - it gives an image of better quality than LCD matrix, the plasma is cheaper.
What type of array to choose depends not only on the user's preferences, but on the budget. Even the cheapest model can have an optimal combination of image quality and smart TV features.
interfaces
For the full implementation of Smart TV technology has to be equipped with interfaces that allow the connection of external devices. It is better if these inputs-outputs will be as much as possible.
To determine the optimal number of them, you need to understand what kind of connector and its purpose:
- standard antenna input of television coaxial cable;
- a connector for TV satellite dishes (DVB-S or DVB-S2);
- a multimedia interface for receiving a high definition TV signal (HDMI);
- multicontact combined input for input-output of image and sound (SCART);
- VGA connector for video broadcast from the computer;
- three-component socket for transmitting analog video signal (D-SUB);
- USB connector for external storage.
Internet Connection
There are two ways to Smart-TV connection to the cable connection through the Ethernet port and Wi-Fi connection via a router. Which one to choose depends on the specific conditions. It is better when the TV supports both connection options.
Ethernet cable makes it easier to load movies Full HD-quality, smaller brakes, provides a more stable signal. With Wi-Fi Smart-TV connection reduces the consumption of resources and time to connect.
file formats
When buying, select the TV set, which is compatible with most file formats, such as MP4, WMV, MKV, WMA, DivX and others. Some models do not work with these formats, which limits their opportunities.
Software
Benefits of Smart-TV user are disclosed in a variety of applications. Always find out what applications are included with the basic installation, as well as whether there is a Russified and paid software.
A variety of applications depending on the TV operating system:
- OS Android - more application programs as earlier was used for intelligent TV.
- OS Windows - only recently applied for this purpose.
Software for Smart-TV is constantly updated, so you can always add to or improve the existing functions.
3D technology
This technology is a three-dimensional image transfer. It can be passive or active. Today comes more and more high-quality 3D movies and movies with a Russian voice acting. Therefore, this technology will diversify watching movies at home.
