Although the 8K TVs have all come out, but the price is not cheap. For those who don't require too much, 4K TVs are absolutely enough in four years. The average renewal of a TV is no less than 5 years, so for those who want to buy 4K TV, how to choose a 4K TV with high cost performance?
First of all, what do we have to know about 4K TV?
According to the definition given by the International Telecommunication Union, 4K TV refers to ultra-high definition TV with a display resolution of 3840 × 2160 and above, which is 8 times higher than HD and 4 times higher than full HD. In such a high resolution, the audience can see every close-up and detail in the TV picture. By using the new generation of high-definition technology, the 4K TV will be highly praised.
So let's take a look at what the real 4K TV needs?
Is the screen 4K Ultra HD?
4K TV must be equipped with a professional 4K screen, with a resolution of 3840 × 2160 and a pixel of 8294400. If the parameter is lower than this number, it's a fake 4K TV.
Is it a 4K decoding chip?
Users want to watch real 4K video, that is, they need to ensure the 4K picture quality of the film source, transmission and display process. Because the picture quality of 4K video is improved, the requirements for the TV processor are higher. The TV needs to be equipped with a professional 4K decoding chip to ensure the ultra-high definition of the video.
HDR high dynamic contrast?
At present, some of the selling points of TV in the market publicize the high dynamic contrast of HDR, which is actually one of the real 4K standards at present. HDR high dynamic contrast can effectively improve the image quality, bring more vivid picture effect, improve the contrast, and at the same time, intelligently adjust the brightness of the screen area, adjust the color gamut, and show more rich and delicate picture details.
Is HDMI2.0 data transmission available?
HDMI 2.0 is a standard in data transmission, so both playback device and display output device must support HDMI 2.0 to be a complete 4K output. Compared with the previous version 1.4, the main improvement of HDMI 2.0 is that the bandwidth is doubled, from the previous 4K / 30Hz output to 4K / 60Hz.
Therefore, when purchasing 4K TV, the above conditions must be met to be a real 4K TV.
What is the recommended price-effective 4K TV?
Sony U8G is about 4469 yuan. X1 high quality image processing chip, motionflow XL motion compensation with brush frequency of 100Hz, unique wide color gamut technology, high A73 quad core processor and 3GB of running memory.

55-inch Hisense's E5D is about 3189 yuan. LCD TV 4K resolution, supporting MEMC motion picture compensation, Dolby DTS audio decoding. Built in 2GB + 32GB storage combination.
If you think it's too expensive, you can also choose Xiaomi TV E55A full screen HDR at 1799 yuan.
The above is for reference only, and it depends on personal preferences.
