What you need to know about TV screen resolution?

An important role in the quality of the image is played by the TV screen resolution. This parameter will have its effect regardless of the type of matrix and diagonal of the technical device. As a result, the viewer will either receive satisfaction from viewing, or be annoyed by the poor quality picture. What is meant by the term "permission"? What is the difference between different models and what is the best screen resolution for a TV?

What is permission?

To understand this term, it is important to remember that the image on the screen consists of the smallest dots - pixels. Regardless of the type of matrix used (internal construction of crystals and the number of electrodes), the specific number of pixels in height and the width of the display determines its resolution.

The more points are involved in the construction of the picture, the smoother will be its lines and the overall frame will be more clearly visible. At low resolutions, people and objects can acquire jagged, angular contours.

There is also the concept of aspect ratio. It can be 3 x 4 or 16 x 9. This is how the viewer will see the image - almost square or rectangular. If necessary, some models are able to stretch the picture if it does not match the screen settings.

If you choose the wrong resolution when buying a device, then you can either not feel the benefits of high performance or be upset by the poor image quality. In the concept of resolution, the rule of declining quality towards the lowest indicator often applies. Here's how it applies:

1. For example, if the TV screen is good, with a high number of pixels, but a movie downloaded from the Internet has lower resolution, then the picture quality will be unsatisfactory. Here "wins" a lower value.
2. Another example: High quality downloaded content is viewed on a small screen. Despite the quality of the file, a small display will not be able to convey the full clarity of the picture, and the visual effect will be unsatisfactory.

Which resolution is better: influencing factors

When determining the resolution settings for a television device, it is important to determine what quality of video will be viewed on it. There are other factors. Understanding the main differences in the video, you can choose a TV model that meets the specific requirements for the quality of the picture, the viewing of which will be associated with rest and relaxation, and not outrage and hostility.

DVD

If the device is purchased primarily for viewing materials from DVD media, it is worth noting that the number of pixels responsible for image quality in this format is 720 x 576. This means that regardless of the screen settings, even if they are 500 or more points exceed the video from the disk, the picture itself will not get better.

For such purposes, budget models with the same number of points as the content on the disk are suitable. They can be used in:

• karaoke bars;
• demonstrations of school material in the lesson;
• scroll advertising in transport.

Antenna signal

If a television device is bought to watch movies and programs from satellite dishes and other signal sources, then two factors are important here: the type of signal and the processor power of the device. In order to transmit media content from television companies to viewers, PAL and SECAM signals are used in Europe and Asia.

They broadcast an image with a ratio of 720 x 576. And in order to give it an appropriate quality when viewing, the TV processor comes into play, which increases the quality of the incoming content to the screen settings.

Therefore, if a technical device is purchased for watching television channels, it is important to verify the microprocessor's ability to optimize the incoming signal. If such a function is on top, then any picture will be adjusted to the screen resolution. Here you can give preference to the parameters of 1280 x 720 or even allow 1920 x 1080. But such models are expensive.

the Internet

If the device is purchased for presentations from flash media or watching multimedia from the Internet, then everything depends on the quality of the downloaded material. If it is low, then even a high-resolution screen will not show a satisfactory result.

But on the Internet there are many films and clips with a number of 1024 x 720 and 1920 x 1080 pixels. This will allow you to enjoy a clear image directly, without the participation of the processor in the stream conversion.

Distance

An important role is played by the distance at which the viewer will be from the screen. The farther it is, the less clearly visible the picture. Therefore, if a TV is bought for a small family that can sit two meters from a 45 inch screen with a resolution of 1920 x 1080 pixels, then they will enjoy the reproduced image.

With a similar display in the conference room, spectators sitting 5 meters away will no longer feel all the charms of high resolution, and here you can limit yourself to 1280 x 720 or even smaller.

Popular Standards

From modern TVs, several applicable standards can be distinguished and the advantage of their resolution for a specific situation can be noted:

1. 852 x 480. A rather rare number of points for displaying a picture, but it is perfect for watching satellite channels on an inexpensive TV. Supports displaying pictures of 4 x 3 or more stretched version 16 x 9. Enough for a TV in the kitchen no more than 19 inches.
2. 1280 x 720. This figure is well known as HDReady. The era of high-quality images began with it. The screen plays well almost all the content from the Internet. If there is a processor, it optimizes the picture from the antennas. Can be used in the kitchen or in a small room. The optimal diagonal is from 19 to 22 inches.
3. 1920 x 1080. Refers to the most common standard for image reproduction quality today. On the TV label, the presence of this number of dots in the display is indicated by the word FullHD. This screen resolution is better for a 32-inch TV, because it will accurately convey all the details. Introduce this standard in larger models.
4. 4096 x 3072. Recently appeared giant ratio that allows you to watch high-quality media content in great detail. In advertising, such models are referred to as "4K." This resolution is given to televisions with huge diagonals from 55 to 65 inches. The problem is only a small amount of video released for this class of image.

TV channels are in no hurry to switch to this format due to the small client base with such a profile. There are still very few films on the Internet for such a level of TVs. But things can change quickly.

When choosing a resolution for a TV, it is worth remembering that the higher the number of points responsible for reproducing a picture, the clearer the latter will be for the viewer. But the presence of a huge number of pixels does not always imply automatic image quality, since this also depends on the resolution of the material itself and the distance to the screen.
