Which parameters need to look at buying TV? Must pay attention to these four points

1, picture quality

In the first place, of course, is the quality of the picture. The most important thing to buy a TV is definitely the picture quality. The parameters related to image quality include color gamut, HDR, and the like.

The gamut is the range of colors that can be represented by the range of colors. The horseshoe-type chromaticity diagram below is probably not new to you. It was proposed by the CIE International Commission on Illumination in 1931. The horseshoe-shaped area is the visible range of color gamut. The color gamut of ordinary LCD TVs is generally about 74%, while the wide color gamut TV can reach about 90%. The higher color gamut means TV can display richer colors, and the screen is not only bright and more realistic, although the wide color gamut is Can not directly represent a good picture quality, but good quality television must have a high color gamut coverage.

Let's take a look at the HDRs that have been hot for the past two years. HDR is an abbreviation for High-Dynamic Range. It was first applied in the field of photography, and it is mainly used to display rich and dark information on television. However, HDR is not a technology but a collective term for display effects.

CHANGHONG 55D2P

Innovating to join the HDR10 picture quality solution will bring you a breakthrough in picture quality. When you open the Changhong D2P, you can experience distinctive images and color performance.

Can carry on the detailed analysis to the picture, and control the brightness of each backlight area independently, the brighter scene is brighter, the darker scene is darker, thus achieves the high quality picture quality and the outstanding light and shadow effect. To restore true colors, the more realistic the more happy.

2, sound quality

The sound quality is also very important for TVs. However, nowadays TVs are getting thinner and thinner, and the sound quality is even worse than the early CRT TVs. Although the content is more and more abundant, the sound is dry and powerless. It affects the overall viewing experience. In fact, it is pursuing. There is no complete contradiction between the slim design and good sound quality.

Conchs Sound is an independent front-facing audio system with direct front-to-back audio, reducing the loss of sound, providing a good level of detail, high loudness, and high fidelity.

Improves the direction of sound reinforcement in previous televisions, allowing sounds to be emitted naturally, without being emitted by walls or desktops. Sounds and images are synchronized into the viewer's brain.

3, hardware configuration

Because the smart TV is equipped with an operating system, the hardware configuration has to keep up, just as when we were buying a mobile phone, we must buy those with high configuration, so that we can use it to be smooth and non-stopping. Judging the level of a TV hardware configuration mainly depends on the processor, memory, flash memory and other parameters.

Select TV to see the number of CPU cores, equipped with 4-core CPU, performance monsters, with the ability to handle a variety of tasks, according to your needs to improve processing speed and energy efficiency, so that viewing video entertainment more smoothly.

Strong performance, so that exciting and timely presentation! In the off state, turning on the TV to watch the program takes only 1.9 seconds. The unopened smart application will also be turned on within 3 seconds of turning on the TV.

4, appearance process

The progress of science and technology in television has been markedly improved. The borders, bases, and other parts are basically made of metal materials. After anodizing, drilling and other processes are processed and graded, even the back design is very elegant, not hesitate to use metal. Materials, drawing process, etc., are getting higher and higher. In addition, the design trend of full-screen is now very popular, not only in the mobile phone industry, "full-screen" TV because it reduces the constraints of the border, when watching TV can bring good results. At present, many TVs have ultra-narrow frame design as a selling point. When watching TV, there is basically no bound to the frame. This kind of extreme process that can enhance visual enjoyment is worth praising.

The above are four aspects that should be paid attention to when buying a TV now. Especially attention must be paid to the quality of the picture, because it can directly reflect the technical strength of a TV, and the TV with excellent picture quality is generally provided with sound quality and hardware configuration. Appearance and other aspects are also more sophisticated.
