There is no doubt that 4K TV is already a trending product. If you move to a new home or want to upgrade, plus 4K products are more and more abundant, mid-range products are more and more abundant, 4K TV is obviously the most Good choice.
However, the controversy over the 4K TV has not been settled. Some professional critics and practitioners hold the view that whether or not the utility is a black and white thing, even if all the high-end TVs in the market are now 4K, it does not mean They are all excellent. Regardless of whether it is purchased or not, as a consumer, we may wish to look at this from a few perspectives to understand the reasons for temporarily not buying 4K TV.
clearer? Maybe you can't see it
The biggest feature of 4K is resolution, and more pixels are integrated in a LCD panel. In theory, the visual effects will be more clear and delicate. However, the theory does not apply to all real-life scenarios. It is even misleading. This is something that needs to be explored.
Obviously, watching TV requires the use of eyes, and the human eye has limitations in its ability to recognize pixels. A situation similar to the Sony 4K mobile phone, its 5.2-inch screen integrated 38202160 pixels, pixel density up to 806ppi, although theoretically more clear, but in the handheld distance (25 to 30 cm), the human eye basically can not identify more than 300ppi above Pixels (Jobs' Retina Screen Theory).
Similarly, TV is the center of each family's living room, with a fixed position. The viewing distance is usually 2-3 meters from the sofa. At this distance, the human eye cannot distinguish between the 55-inch and 60-inch 4K and 1080P TVs. difference. After all, we don't stick our faces on TV to watch content. If you have the ability to buy a 100-inch TV, 4K and 1080P should be clearly different with the same viewing distance, but this is an unrealistic dream for most families.
4K content: Cable, physical media and streaming media are not universal
Even with the ability to purchase oversized 4K TVs, one question that cannot be overlooked is: What is the quality of content you look at with 4K TV? The answer may be disappointing. Take the domestic example. Currently, the resolution of SDTV is still 480P, while the HD standard is 720P. Even if the network bandwidth can achieve ultra-clear streaming media, the resolution is only 1080P. Real 4K content? At present, only a handful of foreign streaming media vendors provide limited 4K content. Ultra-clear Blu-ray discs are still on the road. As for cable television, there is no chance at all.
Another problem is network bandwidth. Even if the 4K streaming media content gradually increases, the bandwidth requirement is very strict. For example, Netflix recommends that the user's bandwidth is at least 25 Mbps. Although many users already use 100Mbps optical fiber networks, they should not neglect the complexity of the network. At the same time, families obviously have more than one network device. Therefore, the popularity of 4K streaming media is still difficult.
In the end, the 4K TV that you are spending heavily on can only look at 480P, 720P and 1080P content, while the popularity of 4K content is still out of reach. This experience is obviously incomplete.
summary
It should be noted that 4K resolution is a basic configuration. In simple terms, the flagship models of TV makers such as Sony and Samsung are not only equipped with 4K panels, but also some high-tech display technologies, intelligent systems, etc. New technology may not appear in the mid-range 1080P TV, which is undoubtedly a marketing strategy for the manufacturers. So maybe you can't avoid buying a 4K TV, but at the very least, don't expect too much.
