Do you really understand 4K TV? Resolution is not a hard standard for effect

If you're thinking of buying a new TV, 4K is obviously the first thing to consider. Of course, there are always some misunderstandings about new technologies. Here are some things you should pay attention to before buying a 4K TV.

Is 4K TV clearer?

There is no doubt that 4K has much more pixels than 1080P in the same 55-inch size, but will you get a very obvious improvement in clarity? Not necessarily. Paul Gray, chief analyst at IHS, said that if you are 1.6 meters away from the TV, you need an 84-inch TV to distinguish the difference between 4K and 1080P with the naked eye. But obviously, ordinary families will not buy such a large TV.

What are the advantages of 4K TV?

If the resolution is actually limited at a certain viewing distance, what is the point of 4K TV? Since 4K has become a standard feature of many high-end TV brands, their selling points come more from new display technologies. IHS research found that color and higher frame rates are more effective in improving display effects. In other words, new features such as quantum dots, HDR, and 120Hz refresh rates can achieve a better viewing experience, and TVs with these features actually use the 4K standard.

As for 4K content, it still cannot meet the needs of users at present. Although foreign streaming platforms such as Netflix have begun to launch 4K video content, the coverage is still relatively limited. In terms of physical media, 4K Blu-ray movie resources are still relatively limited. As for 4K broadcasting and television, the basic bandwidth requirements are higher, and it will take time to popularize. In other words, after buying a 4K TV, the biggest use may still be to watch 1080P content.

What about 4K phones?

Soon, we will see mobile phones with pixel density exceeding 700ppi (6.2 inches, 3840*2160 pixels) on the market, which are true 4K phones. So, does 4K make sense for mobile devices such as mobile phones? As mentioned earlier, at a fixed viewing distance, there may be no difference between 2K and 4K phones, but it may improve the precision of some languages ​​and texts. But realistically speaking, 4K phones may be more of a hardware upgrade, and mobile phone manufacturers have not yet found a way to truly leverage their advantages.

summary

But then again, regardless of whether 4K is practical at this stage, it is a trend. Perhaps soon, 1080P TVs on the market will completely disappear, and 4K will become the only choice. But it is certain that resolution is not the only criterion for determining display effects.
