Content and display terminals are actually interdependent. Without content, the display terminal is useless; there is no display terminal, and the content is also like a mirage.
Following Sharp's first sale of large-screen 8K-definition TVs in China in 2015, Hisense released a 65-inch 8K TV in April and will be available for sale in May. In the era when 4K has not really been popularized, will it be the pursuit of TV consumption in the promotion of 8K? For a time, 8K has entered the turbulence of the television industry.
The so-called 8K TV means that the resolution of the TV has reached 7680×4320, which is 4 times that of the 4K TV and 16 times that of the 1080P, which is the definition standard of the Super Hi-Vision technology.
There is no doubt that the development of TV display terminals to the level of 8K is technically enough to make consumers paralyzed. For enterprises, it is also a benchmark technology. It may be too early to enter the consumer sector. 
As mentioned earlier, the content and display terminals are interdependent, and the content and display terminals are in a synchronized state is a vision, but unfortunately, these two do not belong to the same industry, walking together is just an ideal state. So, what can you watch with an 8K-definition TV? First of all, it is undeniable that 8K sources are now almost zero. Even if major content companies are vigorously developing 4K sources, this is also the last two years. There are no 4K resources. It is also not realistic at the cost to skip over it and to develop 8K resources. At the same time, the pressure of high-definition film sources for broadband is also huge, most of the broadband speeds of ordinary users can not play 4K movies in real time, not to mention the huge 8K film sources, and not to mention the big problem of local storage.
There are rumors that at this year's Rio Olympic Games, 8k television signals will be broadcast, but it must also be a small-scale one. Only the technologies used in major events, and the real popularity of 8k live television may be after 2020. As for China, with reference to the current popularity of Full HD programs in China, we know the popularity of 4K programs and the popularity of 8K programs may not be realized in the short term. Buying an 8k TV and looking forward to seeing 8k in 10 years? Obviously this is not realistic. 
8K is just the level of progress that manufacturers use to demonstrate display technology, which is of no real significance to the average consumer. The impact of the mobile industry, the changing habits of the audience, and the lack of quality consumer content have reshaped this industry rule that has lasted for decades. Nowadays, TV manufacturers are not only competing with TV manufacturers, but also with computers and mobile phones. Tablets and even cinemas compete for people's attention and wallets.
Instead of saying that people do not watch TV, it's better to say that something better looking is attracting people's attention. At this point, these 8K resolutions as a technology lead may not necessarily lead the consumer. The sales of 8K resolution TVs listed by Sharp last year are enough to prove this fact.
1080p popularity has difficulty 8K resolution into the air loft?
Now that the domestic TV industry is facing such a dilemma, the penetration rate of 4K TVs is already very high, and the resolution of live video still stays at 720p and 1080p, and the content is thrown off too much by the display. In this case, Hisense introduced 8k resolution, and even with the extremely lack of 4k video resources, the presence of 8k seems to be meaningless.
