Forbes: 4K TV and 1080P picture quality are not much different

There is no doubt that 4K TV is not a trend, but a general attribute of TV products. After all, technology needs to evolve and products need to evolve. However, in most cases, 4K TV is like "the emperor's new clothes", which is actually meaningless.

"Forbes" wrote that the viewing effect of television is related to human vision, viewing distance, TV size and resolution. Use an example to illustrate: You sit on the lawn of the park, look down at the lawn under your feet, you can distinguish the individual leaves; but if the lawn is 0.7 meters away, obviously can not distinguish the leaves, just see a probably, TV The same is true.

Then, based on the visual acuity of 2.0, what conditions do you need to meet if you want to see the details on the 4K TV? After scientific research, you can find the answer through the above picture. If you list 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, it is 4 feet (about 1.2 meters). Obviously, the 55-inch is the size that most families usually choose, and the viewing distance of 0.7 meters can distinguish the 4K quality from the 1080P, but almost no one puts the face on the TV screen.

Is there a better solution? Yes, but it is costly. You can get a 4K detail experience while adding a larger TV to your viewing distance. For example, a 105-inch oversized TV can see very clear 4K details at a distance of 7 feet (about 2.1 meters). Price? Samsung and LG's 105-inch TV will cost at least $100,000 (about RMB 663,000), of course you have to have a large enough living room.

So, since the meaning is not big, why should TV manufacturers spare no effort to promote 4K TV? As mentioned above, manufacturers need new concepts and new technologies to make new products more selling points, gain profits, and the average consumer does not. It will be so true, calculate the best viewing distance, and feel better.

Of course, 4K TV is not completely worthless. The quantum dot and HDR technology that manufacturers have introduced on this basis can make the picture look more realistic, and the color and contrast are more outstanding. This is worthy of recognition. Most importantly, 1080P HDR TVs are basically not found in the market.
