Ultra HD LED TVs Have Become Mainstream

Ultra HD LED TVs have become mainstream

There is no doubt that UHD LED TVs are no longer a trend, but a regular attribute of TV products. After all, technology needs to evolve, and products need to evolve.

However, "Forbes" wrote that the viewing effect of TV is related to human vision, viewing distance, TV size and resolution. Use an example to illustrate: you are sitting on the lawn in the park, looking down at the lawn under your feet, you can distinguish individual leaves; but if the lawn is 0.7 meters away, you can no longer distinguish the leaves, just see an approximate, TV The same is true.

So, based on 2.0 vision, what conditions do you need to meet if you want to see the details on a 4K TV? After scientific research, you can find the answer through the above picture. If you list a specific value, the viewing distance of a 55-inch 4K TV is 2.5 feet (about 0.7 meters), and the viewing distance of 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 tell the difference between 4K picture quality and 1080P, but almost no one sticks their faces on the TV screen to watch.

Is there a better solution? Yes, but at a high cost. You can get a 4K detail experience while increasing the viewing distance by buying a larger TV. For example, a large 105-inch TV can see very clear 4K details at a distance of 7 feet (about 2.1 meters). Price? 105-inch TVs from Samsung and LG cost at least $100,000 (about 663,000 yuan), and of course you have to have a large enough living room.
