If we want TV to provide us with the best viewing service, then we must first have a high quality and cost-effective TV. However, there are many types of TV on the market, and the brands are also uneven and have advantages and disadvantages. In so many TV products, how should we identify what TV is good to buy? In fact, as long as you master these aspects introduced in the following article, then the purchase of TV will become very easy.
First, what parameters do you want to see when buying TV
Screen type, size, and resolution are the most basic and important parameters of a TV. Screen size, in particular, is one of the most important benchmarks for users to buy a TV. Although consumers can think of these points when buying a TV, there are still some points that need to be noted.
Second, each screen type has its own characteristics
In terms of the mainstream LCD TV panel types on the market, there are three most common screen types. One is a general soft screen, one is an IPS hard screen, and one is an X supercrystalline screen. The current TV soft screen is basically all VA soft screen panels, the cost of this panel is relatively low, the effect is not bad. Among them, the VA screen of the Korean Samsung brand with its picture quality optimization technology can show first-class excellent picture quality. And in the general soft screen, it will be divided into A+, A, B, C level screens according to the advantages and disadvantages of the panel. The panel of the flat screen TV must be at least grade A to be considered qualified. Relatively speaking, A+ level screen will have a better performance in terms of image color, screen brightness, clarity, etc.
1. Resolution
The resolution of a television is affected by pixels that have a fixed primary color, and a pixel consists of three sub-pixels (R, G, B). The higher the resolution of the TV, the more detailed the screen picture, the more obvious the layer. Among the types of TV panels currently available, 4K ultra HD TVS are the hottest. But what does 4K actually mean? The so-called 4K TV refers to a 4096×2160 pixel resolution TV, which is four times the resolution of 2K projectors and high-definition TVS. For the TV, the screen resolution must reach 3840×2160, and the clarity of 4K is exactly four times that of the traditional 1080p full HD, so it is also known as ultra-high definition or UHD. At present, there are many fake 4K products on the market, if you are strict about the quality of the picture, you may wish to take a look at the following article recommended to distinguish between true and false 4K.
2. Brightness/contrast
Because each producer does not have a uniform standard for brightness and contrast, it is still based on our visual inspection. The general step is to go to a physical store, stand 5 meters away from the TV, and carefully observe and compare the brightness and contrast of different brands of TV screens. It should be noted that because the light in the store is different, the shopper will mostly reset the brightness and contrast of the TV according to the field light. Pay attention to the parameter Settings while watching.
3. Tail
The tailing phenomenon refers to the blur phenomenon that occurs when the TV displays high-speed dynamic pictures. The tailing phenomenon has a great impact on the users who like watching sports games and games. The main reason for the phenomenon of TV tailing is the response time of TV, the faster the response time of TV, the less the phenomenon of tailing. If it is in a physical store, you can ask the shopper to play an action movie on the spot for naked eye observation.
Third, the size of the purchase
Now the screen size purchase is not too limited, unlike the previous viewing distance of a few meters have to choose a large, with the price of large-size panels down, the previous size limit is now basically a fallacy. Home 3.5 meters away to see a 65 inch really do not feel big, of course, taking into account the cost performance, medium and large units can consider 55 inches, small and medium-sized units can consider 48~50 inches, the basic 40 inches in the room can meet, of course, now there are many large size low price machines, For example, the price is less than 4000 can buy a 60-inch Hisense, 65-inch Haier. As for these God price machine in the end is worth buying, the qualification is left to friends who have bought, in short, now the choice of screen size is better than small, of course, there are many feel that enough is good, big can not stand, this kind of friends will honestly choose a comfortable size to look at.
