How about 4K TV? Is it practical?

4K TV has obvious advantages, but it is not practical enough.

Advantages of 4K TV:

1, high screen resolution. The playing picture can be clear and natural.

2. Quick response. 4K TV is equipped with high-end hardware, which has very strong computing power and can respond to the user's operation behavior more quickly.

3. Wide color gamut. 4K TV sets are mostly improved in image quality, with wide color gamut, which can easily express various color qualities that 1080P TV sets cannot, and are closer to reality.

4, 4K area. A 4K TV set without a 4K film and television area cannot be called a 4K TV set. Users buy 4K TVs just to watch 4K videos. What's your use if you don't have them? So most 4K TVs have 4K zones. Don't worry, there is no 4K source to watch. Downloading is really too much trouble.

Second, the shortcomings of 4K TV:

1, the film source is in short supply. Although the 4K TV has built a 4K zone, the update speed is very slow, which is far from meeting the needs of users.

2. It is impossible to play real 4K images. At present, most of the 4K TVs have the technology of converting from 2K to 4K, which is to improve the picture quality of 1080P movies to 4K level. However, no movie can really achieve 4K resolution.

3, the power consumption is very large.

4, the network is still very persistent, without 10M fiber, you can't watch 4K movies.

5. When playing 1080P movie, the picture quality of 4K TV is similar to that of 1080P TV.

6. 4K TV can only play 4K movies, and can only decode movies with less than 30 frames. Today's 4K TV can't decode movies after 60 frames.
