What parameters should you look at when buying a TV? Pay attention to these four points

Double 11 is a good time to buy TVs, especially at the beginning of the year, when the TV industry experienced a round of price increases due to rising raw material prices. However, as upstream raw material prices gradually fall, a large wave of promotions will begin in the upcoming Double 11.

Generally speaking, the price of TVs is getting cheaper and cheaper. However, many users suddenly become confused when buying TVs. Let's take a look at what parameters we should consider when buying a TV.

1. Image quality

The first thing that comes first is of course picture quality. The most important thing when buying a TV is definitely the picture quality. However, many TV brands nowadays do not pay enough attention to picture quality, or even avoid the important issue and focus their main energy on promoting some flashy things, such as how thin the body is, how much content is twice as much as the competitors, etc. This can be said to be putting the cart before the horse.

Parameters related to image quality include color gamut, HDR, etc. The color gamut is the range of the number of colors that can be expressed. You may be familiar with the horseshoe-shaped chromaticity diagram below, which was proposed by the CIE International Illumination Commission in 1931.

The horseshoe-shaped area is the color gamut range visible to the naked eye. The color gamut range that each TV can display is represented by a triangular area formed by connecting three RGB points. The larger the area of ​​the triangle, the larger the color gamut range.

The color gamut value of ordinary LCD TVs is generally around 74%, while that of wide color gamut TVs can reach around 90%.

Because KSF fluorescent crystal and color filter technology are used to improve the purity of the backlight, the color gamut coverage is improved while avoiding cadmium pollution, making it healthy and environmentally friendly.

The higher the color gamut, the richer the color that the TV can display. The picture is not only brighter but also more realistic. Although a wide color gamut does not directly represent good picture quality, a TV with good picture quality must have a higher color gamut coverage.

Let's take a look at HDR, which has been very popular in the past two years. HDR is the abbreviation of High-Dynamic Range. It was first used in the field of photography and is mainly used in television to present rich light and dark information.

Although there are more and more HDR TVs now, most HDR TVs will only be effective when playing HDR sources.

2. Sound quality

Sound quality is also very important for TVs, but now TVs are getting thinner and thinner, and the sound quality is even worse than early CRT TVs. Although the content is becoming richer and richer, the sound is dry and weak, which greatly affects the overall viewing experience. Therefore, be sure to listen to the sound effect when purchasing.

3. Hardware Configuration

Because smart TVs are equipped with operating systems, their hardware configurations must also keep up, just like when we buy mobile phones, we must buy those with high configurations so that they can be used smoothly without lags. The hardware configuration of a TV is mainly determined by parameters such as the processor, memory, and flash memory. Among them, the combination of 2GB memory + 16GB flash memory is currently more common, which is enough for at least 3-4 years.

4. Appearance technology

With technological advances, the craftsmanship of televisions has been significantly improved. The frames, bases and other parts are basically made of metal. After anodizing, drilling and cutting, they look very classy. Even the back design is very sophisticated, using metal materials and brushed techniques, and the appearance is getting higher and higher.

In addition, the full-screen design trend is very popular now, not only in the mobile phone industry. "Full-screen" TVs can bring good effects when watching TV because they reduce the constraints of the borders.

The above are four aspects that you should pay attention to when buying a TV now. In particular, you should pay attention to the picture quality, because it can directly reflect the technical strength of a TV. Moreover, TVs with excellent picture quality are generally more advanced in sound quality, hardware configuration, appearance craftsmanship, etc.

If you are going to buy a TV during the upcoming Double 11, you must be rational about the various promotional terms and don’t be led astray.
