Recently, a friend sent me a micro-letter and told me that he had grabbed a 50-inch 4K TV and it was only 1999 yuan. It was very cheap. Another is to send product pictures, but also send buy links, let me quickly buy do not hesitate, there is a kind of do not buy it will lose hundreds of millions of feelings. Oh, this friend is not engaged in TV shopping or sales. But when recommending this product to me, I really want him to try TV shopping.
He was so zealously recommended, and I also responded enthusiastically to him and said that I would buy it right away. It was a good deal! Actually, I didn't want to throw him cold water. But after thinking about it, if I didn't tell him, I would let him be pitted. So I decided to write down the following content, and then forwarded to the circle of friends, not to mention he would certainly look.
As you all know, the resolution of a TV is the same as that of a mobile phone. It is considered as a battleground for the military. When people are complacent about a 2K TV, you quietly release a 4K new product. Can attract the eyeball, but also establish an industry dominance. The consumer's preference is to buy new ones and not buy them for a long time. Many people do not know what 4K is for, but they have already looked down on the 1080P TV, and the 4K is the first element in the purchase of TV. .
Buying a TV without even knowing 4K is like trying to marry a wife. Even if the name doesn't even know, it's how it works. So we need to come to popularity first:
What is 4K in the end?
To know what 4K is, we must know that the size of the image can be expressed in pixel resolution. For example, a resolution of 1920×1080 means that the image is composed of 1920 horizontal pixels per line and 1080 pixels vertically. of. For the sake of convenience, generally use "K" to describe the pixel value, in which 1K is equivalent to 1024 pixels, and several K means that the pixel value of each line in the horizontal direction of the image reaches or approaches several times 1024, for example, the horizontal pixel of 4K is 4096. One. In most cases 4K refers to 4096216 resolution.
And depending on the scope of use, 4K images also have a variety of derived resolutions, such as Full Aperture 4K 4096111, Academy 4K 36566664 and UHDTV standard 38402160 (generally 4K TVs and monitors are such, so buy 4K When the TV found that the resolution is not 40,961,112, don't be skeptical, this is 4K, but the standard is not the same.) And so on, all belong to the category of 4K resolution.
Multi-character fonts are not as good as direct maps. Here we will come to experience how attractive 4K is.
Did you think that you were shocked by 4K and you wanted to replace the 1080P TV in your home? Don't be impulsive before you change, you must know what is true 4K and pseudo 4K! (Nani, buy a 4K is also all routines!)
What is pseudo 4K?
A few years ago when 4K TV came out, there were some TVs only equipped with 4K screens, but the built-in chip did not have 4K video playback capability, or the decoding format was incomplete, which was then called "Fake 4K". This kind of TV is rarely seen in years. After all, this method can be easily distinguished. In the past two years, there has been another kind of “pseudo 4Kâ€. This pseudo 4K is also called 4 color 4K, and the original red (R), green (G), and blue (B) trichromatic liquid crystal molecules are added to white pixels. However, after the red, green, and blue primary colors are formed, they are formed by white pixel molecules. Therefore, TVs do not need to add white sub-pixel molecules, so the cost is drastically reduced. This is why my friend bought a 50-inch 4K TV. Less than 2000, and some are close to 4,000 yuan, the following figure also explains this point well.
Since this world has so much to buy a TV, then we have to have the ability to distinguish between routines, then how to identify true and false 4K?
First, in the face of "false 4K" in previous years, the easiest way is to download H.265 format video on the Internet, install it with a USB flash drive or mobile hard disk, and test it directly. If you can't play it, then you can buy it. Undoubtedly it is a fake 4K TV.
Second, the above is very simple, and the "pseudo-4K" disguised by pixels is not so simple to distinguish, but we can also use some methods to identify.
1, because the "pseudo 4K" TV is RGB three-color weakened, so the picture quality will be significantly reduced, we can see through some high-definition pictures or 4K power, if there is another real 4K TV at home, can be used to do In contrast, this can be compared more clearly.
2, you can use the phone's camera to shoot the TV, if you see mixed in the RGB three-color white pixels, especially the ultra-low-cost products, the more white pixels, it is proved that the RGB trichromatic is weakened, the more fake The possibility is also higher.
3, look at the certification mark of the authority, and see the product's promotional materials or screen specifications are "RGBW" words, the normal 4K TV pixel arrangement is RGB, and "pseudo 4K" pixel arrangement is RGBW.
4, not greedy cheap, ready to buy 4K TV, take a look at the first-line big 4K TV price segment is how much, if you are ready to buy 4K TV prices and their gap is great, you have to be careful, maybe it is "pseudo 4K" TV.
Finally recommend a few good "real 4K" TV, of course, turnip cabbage have love, only hope that everyone will not spend money but buy "pseudo 4K" TV.
