How to distinguish true and false 4K TV, I believe everyone wants to know

4K TV is the hottest and most popular product in the current TV market. When we buy TVs, we naturally target the 4K TV products. But many careful friends will find that some of the so-called 4K TVs only support 4K playback, not the true 4K TV, which is what everyone calls "pseudo 4K." As a result, in the face of the complex 4K TV products on the market, today we will come to understand what is true and false 4K TV. The so-called 4K refers to a video program with a resolution of 3840*2160 pixels and effective pixels of 8.3 million. Its resolution is 4 times that of Full HD (1080P). Compared to 2K (1080P), 4K can express color transitions in more detail, increase color by 80%, and 4K can better reflect the visual experience in the real environment, the perception is more realistic; 4K also can provide more The dynamic range and image details make the picture more delicate and natural.
So how do we distinguish between true and false 4K in the purchase process? First of all, we can use the H.265 encoded video file to test under the same definition. If the 4K TV does not support the 4K video in the H.265 format, it can basically be regarded as “pseudo 4K”. Second, it is to look at its promotional materials or whether the screen specifications have the word “RGBW”. The normal TV pixel arrangement is RGB, and the real 4K screen pixel arrangement is a unique “RGBW” method.
Once again, discriminating between genuine and fake 4K TVs can also be done through professional TV testing tools. For example, when downloading the Assistant, one of the functions for TV screen detection is 4K TV resolution test. Through the test chart, you can clearly understand whether it is a true 4K TV.
In addition, the China Household Electrical Appliances Association also introduced a way to distinguish between genuine and fake 4K TVs, that is, watching through a magnifying glass, a false 4K color is blurred, and when viewed with a magnifying glass, white lines can be seen.
Of course, buying a 4K TV at home does not mean that you can see the 4K effect. If you want to see a true 4K Ultra HD, you also need a 4K source, a device that supports 4K decoding (Set Top Box) and enough network bandwidth. Currently, 4K sources are relatively lacking. TV stations around the world do not officially provide 4K TV broadcasts, nor do they have a 4K Blu-ray video distribution. Internet downloads can only be downloaded to some 4K video clips or demos.
However, in recent years, with the continuous maturation of 4K technology, many companies have begun to lay out 4K content. For example, Guangdong Guangdong Power Grid has started the 4K TV network application action plan and is applying to the National Press and SARFT Bureau to fully prepare for the construction of the 4K ultra high definition channel. It is expected that the first 4K ultra high definition television channel will be officially launched before the end of this year. If you want to buy the TV is not eliminated, 4K TV is worth our choice.
