What exactly is 4K TV? What should I pay attention to when buying a 4K TV?

In recent years, with the continuous maturity of 4K technology, 4K TV has gradually become the mainstream product of color TV market. So for 4K TV, what is 4K TV? What should we pay attention to in purchasing? Here are a few things to note:

First of all, we should have a certain understanding of the concept of 4K TV. 4K is a kind of high-definition display technology, which is widely used in TV and mobile phone industries. In the TV standard, 4K is ultra-high definition (UHD). Its horizontal resolution is 3840 pixels, and its vertical resolution is 2160 pixels. In addition to the professional UHD ultra-high definition display screen, the physical resolution of 4K TV must also meet this standard. Only when the pixel is 8.3 million can it be called the real 4K electricity.

After having a certain understanding of the concept of 4K TV, let's see what we should pay attention to in the purchase.

The first thing to do is to identify the authenticity of 4K. The correct pixel arrangement of 4K TV is in the form of "RGB". If "RGBW" is marked in the manual, it is not a real 4K TV. In addition, the real 4K TV will obtain the 4K Ultra HD certification of CEA Consumer Electronics Association. When you buy TV, you should find the certified of 4K TV.

Secondly, when purchasing 4K TV, you should also consider your own viewing needs and choose products that are more suitable for you. For example, it can support 120 Hz refresh rate TV, watch tennis match with 4K resolution and high frame rate, and even see the moment when players swing. For sports fans, they can enjoy more wonderful moments of the game, and the number of pixels does not represent the picture quality.

Also, check the chip. Chip is a key factor for TV to give full play to 4K advantage. In the TV set with 4K screen, the key is to obtain 4K image effect, which depends on whether the processing chip adapted to 4K screen technology is adopted.

In addition, boot directly watching the actual effect of television. A good product is not a simple assembly of the best parts. When judging the 4K effect, it can be easily judged by "2K to 4K image quality improvement technology". You can turn on the product "2K to 4K function" and observe the difference between the pictures when the function is turned on or not, so that you can intuitively understand the actual application effect of 4K technology.
