Select the resolution of the TV screen for a better image.

Buying a TV, everyone wants select by their parameters the best and most successful model in which there would be many interesting features and high-quality image. The high cost of such a technique is not at all the key to displaying a realistic picture. Dear TV, with built-in innovative technologies, sometimes gives a blurred image. This effect can cause a difference in the resolution of the matrix and the format of the incoming video. So, what should be the resolution of the TV screen for a high-quality contrast image?

What determines the quality of the image

The transmission of the video signal and its display affects number of pixels and display backlight.The more pixels, the more the ability of the TV to play high-resolution formats. The horizontal and vertical arrangement of the set of cells allows you to transmit clarity, contrast and darkening, which ensures the display of the most real image. Of course, a good image also depends on the video quality, on the received television signal, and display diagonal.

A TV that supports high resolution Full HD 1920px * 1080 can produce a spreading image if the input signal of an analog television is 720 * 480 pixels, which comes from a conventional antenna. Therefore, choosing a technique, it is necessary first of all to make a start from playable video files. The ideal picture is achieved when the screen resolution and video signals are the same and are presented in high quality. Perhaps for a better image quality it is worth connect satellite tv.

Manufacturers are pleasantly pleased with the variety of models using different technologies that distinguish one option from another. However, from a variety of additional functions and the introduction of innovative systems, the eyes “run up”, and make a decisionWhich TV display parameters are better is very difficult.

Screen resolution and video signal

Components tv pictures

Along with the number of pixels located in the horizontal and vertical plane, the image in the projection and panel screens is influenced by the appearance of the sweep. She may be:

• interlaced and has the designation "i";
• progressive, denoted as "p".

In the first case, the picture is updated in 2 stages every 30 seconds, first even and then odd. Such an effect in a lighted room, with an increased degree of ultraviolet rays, can cause flicker. Progressive scan is better: it has a positive effect on image quality, since every minute simultaneously updates all the lines.

Playback quality also depends on signal decomposition and is divided into the following types: SDTV, EDTV, HDTV and can be decoded as standard signal definition, high and high respectively. These indicators are grouped and determine the type of resolution.

TV resolution depending on its technology

Different types of televisions have their own standards of good image quality.Progress does not stand still, and manufacturers are introducing new technologies that allow the virtual world to transform into reality. To determine which TV resolution is better, consider its types and technologies that provide picture quality.

1. At the origins is the type CRT with a resolution of only 640x480. These are cheap televisions of not very high image quality, but in the conditions of broadcasting only analog television, they will be the best option. For such a TV you can just choose a quality antennaand watch the broadcast channels.
   
2. Projection TV has permission already DLP 1024 x 720 pixelsThat allows you to get a higher quality video signal.
   
3. Liquid crystal LCD and LED TV has several resolution options. The first copies of this technique had permission HD Ready 1366 x 768. In the latest new models, manufacturers have upgraded the screen (increased the diagonal) and presented a technique with a resolution of 1920 x 1080 pixels, which allows you to play Full HD quality. Today it is the most common formats.
   

4. Resolution 4K TV is the development of a new generation.Through a monitor of this quality, it is possible to convey natural colors, contrast and as close as possible to the image to the natural picture. Quality 4R-Ultra HD provides 3840x2160 pixels. These are expensive TVs, which are also equipped with a variety of additional functions: voice control, Skype, Wi-Fi, provides support for 3D format.
   

Almost all 4k TVs support HDR - an extended dynamic range that maximizes the image to reality. But the accuracy of colors and shadows is transmitted only through video on 4k Blue-Ray discs and Netflix video files.

New technologies provide the transfer of colors in natural colors and transmit very clear contours. Modern TVs are equipped with high-resolution screens. But not in all cases this can have a positive effect on the quality of playback - the high accuracy of the display dictates a certain format of the incoming video file.

How to choose a TV with the best resolution

Not necessary TV with a very large diagonal and a large number of pixels will allow you to get the perfect image. Given the source of the signal, you can choose the best option to achieve the best effect. An HD-Ready screen is enough to play cable TV and terrestrial TV signals with a built-in digital DVB tuner.This TV will allow you to play high-quality video and read DVD-format video files. To connect blue-ray, watch satellite tv and use game consoles better fit Full HD screen.
