There is no doubt that 4K TV is not a trend but a regular attribute of television products. After all, technology needs development and products need to evolve. However, 4K TV is like "the emperor's new clothes" in most cases and actually has no meaning.
According to the “Forbes†article, the viewing effect of television is related to human vision, viewing distance, television size and resolution. Use an example to illustrate: you sit on the park lawn, look down at the lawn under your feet, you can distinguish the individual leaves; but if 0.7 meters away from the lawn, obviously can no longer distinguish the leaves, just see an approximate TV The same is true.
So, based on the vision of 2.0, if you want to see the details on the 4K TV, what conditions need to be met? After a scientific study, you can find the answer in the above figure. If you give a specific value, the viewing distance for a 55-inch 4K TV is 2.5 feet (about 0.7 meters), and for a 65-inch TV is 4 feet (about 1.2 meters). Obviously, 55 inches is the size that most families usually choose, and the viewing distance of 0.7 meters can distinguish the difference between 4K picture quality and 1080P, but hardly anyone can put their faces on the TV screen.
So, since there is little significance, why do television manufacturers spare no effort to promote 4K television? As mentioned before, manufacturers need new concepts and new technologies to make new products more profitable and profitable. In addition, general consumers will not be so true. Calculating the best viewing distance will make them feel better.
Of course, 4K TVs are not completely worthless. Quantum dots and HDR technologies based on this technology can make the picture look more realistic and the color and contrast are more outstanding. This is worthy of recognition. The most important thing is that the 1080P HDR TV is basically not found in the market.
