Is 4k TV necessary?
Here are two points to illustrate:
4K TV is clearer
Undoubtedly, with the same size of 55 inches, the number of pixels in 4K is much more than that in 1080P, but will you get a bright and obvious improvement in definition? Not necessarily. IHS Chief Analyst Paul? Gray said that if the viewing distance between you and the TV is 1.6 meters, then you need an 84-inch TV to distinguish the difference between 4K and 1080P with the naked eye. But obviously, the average family won't buy such a big TV.
What are the advantages of 4K TV?
If the improvement of resolution is actually very limited at a certain viewing distance, what is the significance of 4K TV? Since 4K has become the standard configuration of high-end models of many TV brands, their more selling points come from new display technologies. IHS research found that color and higher frame rate are more obvious for improving the display effect. In other words, new functions such as quantum dots, HDR, 120Hz refresh rate can achieve a better viewing experience, and TVs with these functions actually adopt the 4K standard.
As for 4K content, it can't meet the needs of users at present. Although foreign streaming media platforms such as Netflix have begun to launch 4K video content, the coverage is still limited. In terms of physical media, the resources of 4K Blu-ray movies are still relatively limited. For 4K radio and television, the requirement for basic bandwidth is higher, and it will take time for popularization. In other words, after buying a 4K TV, the biggest use may still be watching the content of 1080P.
