4K is an international standard for display technology. The screen resolution of a television must reach 3840×2160. The resolution of 4K is exactly 4 times that of a traditional 1080p full HD, so it is also called Ultra HD or UHD. Although 4K only specifies the sharpness of the screen, it is obviously not enough if the television has only a screen with a resolution of 3840×2160. In order to ensure true 4K ultra high-definition visual enjoyment, the video content displayed on the screen must also reach the level of Ultra HD. 
According to the saying, 4K is an international standard. If it can't reach the resolution of 3840×2160, it cannot be called true 4K. However, there is indeed an LCD screen that has been widely dismissed as a fake 4K screen in the industry. This kind of screen adopts WRGB technology, uses the neighbouring picture element and shares the sub-pixel way to reduce the cost, but this kind of screen has only 6 million picture element in total, and true 4K screen has more than 820 million picture element. 
Since the difference between 6 million pixels and 8.2 million pixels can hardly be distinguished with the naked eye, this fake 4K is the most confusing. The only way is to pay attention to whether there is “WRGB†in the product description when choosing a TV. If so, you can determine that it is a fake 4K. Note: Ultra HD certification may not be reliable. Many 4K TVs on the market will have an “Ultra High Definition Display Certification Specification†issued by an authoritative organization. However, many televisions adopting WRGB technology have also obtained this certification, so it is impossible to identify whether it is true 4K.

TV has long been not a simple display. Connecting a mobile hard disk to play video has become an essential feature of all TVs. Of course, 4K TVs must also be able to play 4K videos. In the early days, many 4K TVs were defined as fake 4K due to lack of this function. The current model can basically play 4K video, but with the emergence of the H.265 format, new problems have arisen. In the 1080p era, H.264 video encoding format is the mainstream, but after entering the 4K era, H.265 is the encoding format for 4K. According to technical data, H.265-encoded video files with the same resolution are only half of H.264, which brings convenience for network transmission or file storage. 
Of course 4K TV will be used to watch 4K sources, otherwise it will waste ultra-high-definition screens. However, the current 4K TVs are faced with a severe situation: There is not a 4K TV station in the world that is officially commercialized, and there is no 4K Blu-ray disc distribution. Internet downloads can only be downloaded to some 4K video clips or demos. The vast majority of 4K TVs don't have any real 4K source. 
Fortunately, there are already some brands of TV sets that provide 4K movie and TV drama sources through online video. For example, TCL added a 4K area to the models that it collaborated with iQIYI and Mango TV, and there are dozens of 4K. the film.
