What if I bought a 4K TV without 4K content?

I have seen a saying that advises people not to buy 4K TVs so early: 4K content is still too low, and 1080p content is poor on 4K TVs. For such arguments, we can only say that the first half is correct, but the latter half is very subtle. Of course, some very old video content will look terrible on 4K TVs, but that is the source of the video, not the pan of the TV. At least for high-quality 1080p content, their performance on 4K TV is not bad. You also don't need to worry that because of buying a new 4K TV, past video content or playback devices cannot be used in new products. In fact, many of the above content are not particularly pointed out, because everyone does not think too much, buy directly to use it. However, if there are friends who have indeed had such concerns, then we can look at the following analysis of popular science. All TVs today have a certain number of pixels, which can be thought of as a small dot (usually a square) that forms the entire screen. If you look closely, you can generally see these pixels. To display an image, the TV has to assign color and brightness to each pixel. For a 4K TV, it has 3,840 pixels per line and 2160 per line, so its so-called "native resolution" is 3840-2160. If the 4K content you want to play is also 3840脳2160, then the TV is easier because each pixel has its own counterpart on the content side. In the case where the aspect ratio of the screen and the video content are 1:1, then the television itself does not need to undergo any conversion process. Of course, if the signal you send to the TV is not the corresponding 4K content, then it needs to be converted. If you don't do this processing, suppose you want to play a Blu-ray movie of 1920x1080, then the picture you see will only be squeezed into a small box in the center of the screen, and all the surrounding pixels will not be used. The experience is too bad. The process of conversion Having said that 4K content is playing on 4K TVs, then it's time to talk about non-4K content. Although major manufacturers and content providers are now actively promoting 4K movies and 4K online video, the vast majority of the entire market is still 4K content, such as movies, radio and television, online video, games and so on. Therefore, it is still meaningful to discuss how 4K TV deals with non-4K content. When dealing with this type of video, the TV uses various algorithms to "guess" what the extra pixels will look like when the image fills the screen. This process is called "upsampling." This process does not require the user to purchase additional conversion equipment because the TV will handle it autonomously. This is different from the forced stretching of large-resolution TVs in the past when playing small-resolution content. Some people may think that, after all, those extra pixels are TVs relying on algorithms to add, which will certainly be inaccurate or wrong place, so the effect will certainly not be good. However, the fact is that technology has been developed until now. In recent years, TV has done a very good job in the up-converting. The vast majority of people do not see what the post-conversion picture has. Practice has proven that if you use a 4K TV to play a high-quality 1080p HD content, then the resulting viewing is as good as it is, and you may even feel that the processing is much clearer than in the past. Of course, the effects of different televisions will surely have different. However, this solution does have its own limitations, especially when 4K TV is playing content below 1080p resolution. Suppose you want 4K TV to handle 720-480 resolution, it means that TV must fill in nearly 8 million new pixels by itself, which is nearly 23 times the number of pixels in the original screen. Existing technology can also handle this situation, but you will not be surprised. Incidentally, this is the case when the quality of the original picture is high. If the original picture itself is very problematic and interferes with the judgment of the conversion algorithm, the final result may be far from being "horrible." To give an inappropriate example, you have a pile of dough that can be full of 10 gimmicks, and you have to make two more, but in fact nobody will notice. However, if you want to use the same dough to make 30 steamed buns, everyone will find it wrong right away. Outside TV All that is said here is the upsampling of television. That's because nowadays, it's ideal enough to rely on television for processing. Of course, this does not mean that Blu-ray players and other devices do not have similar mechanisms. For example, Samsung's 4K Blu-ray players claim to have 4K up-scaling. However, the fact is that, assuming that your 4K TV is not a very bad type, even if the player's converter is much better than the TV, the difference actually generated is minimal. A good up-conversion can make the 1080p content appear almost exactly the same as the 4K display, but it is not difficult to do this now. So, many times we don’t have to worry about buying a 4K TV, but we’ll also need a player or other device with an up-converting function. On the other hand, if the original video is really poor in quality, it is not good to have any good upsampling techniques. Last but not least, if you want to enjoy the most authentic 4K experience, then you still have to look for 4K Blu-ray movies, buy 4K Blu-ray players, or 4K online content on major video sites. In many cases, 4K content is not just a matter of resolution. It is also about HDR, a technology that greatly influences the perception of picture quality. So if there are conditions, of course, serious 4K movies/videos are the best.
