The color TV industry is now full of smart and high-definition TVs, and some manufacturers have even launched 8K high-definition TVs. Traditional domestic color TV companies such as Skyworth, TCL, Samsung, LG, and Sharp have launched their own new high-definition TV products. At the same time, the market has also given corresponding attention. As young people, we have always been eclectic, and our lives are reflected in all aspects. So what kind of non-standard version do we have for TV?

Young people are always defined by fashion trends, and what kind of favor do we have for the choice of color TV? It is undoubtedly good-looking and fun. With such a demand, high-definition and smart are the basis of our choice. How can we choose a cost-effective smart high-definition TV? And how to practice sparkling eyes in the dazzling color TV shopping malls, let's take a look together.

Shopping skills:

1. Whether it is a 4K ultra-high-definition display

Whether it is an ultra-high-definition display can be confirmed by the following three methods:

① Confirm according to the certificate of "National Radio and Television Product Quality Supervision and Inspection Center Evaluation". All products with authoritative certificates. The 6 most important basic indicators of 4K screen and 4K TV should all be qualified.

②Use a microscope camera to observe pixel particles. And compared directly with ordinary TVs of the same size, if the pixel particles are arranged densely, it proves that the product has a high resolution and is a 4K screen.

③ Take a white picture with a digital camera. Comparing the number of pixels in the same area or the same length of a screen of the same size, the 4K screen of the same size has more pixels than the ordinary screen.

2. Check the chip

The chip is a key factor for a TV to give full play to the advantages of 4K. For TVs with 4K screens, obtaining 4K image effects is the key, which depends on whether a processing chip compatible with 4K screen technology is used.

Inspection Method:

Open the "Factory Menu" of the color TV, enter "System Information" and check "Local Information" to see if the processor of the product is quad-core or above. Second, check whether the 4K decoding chip uses a professional 4K decoding chip.

3. Start to watch the actual effect

A good product is not simply assembling good parts together. When judging the 4K effect, observe the difference in the screen image when the function is turned on or not. In this way, you can intuitively understand how the actual application effect of 4K technology is.

4. Check whether the interface meets the 4K ultra-thin TV standard

When purchasing, check whether the TV has USB3.0, HDMI1.4 and above high-speed transmission ports. For the judgment of USB3.0 ports, you can check whether the 4K ultra-high-definition TV has one or more blue ports. For the judgment of the HDMI1.4 port, you can connect to the live demonstration through the HDMI1.4 port, play 4K video, and observe whether it can play normally quickly and the image is smooth.
