Beware of the b-board trap
The lower price of the upstream LCD panel has stimulated the price reduction of the finished display products. However, when there are major fluctuations in the market, there will always be people who fish in troubled waters and do not hesitate to infringe on the interests of consumers. Therefore, the lower price of LCD brings benefits to consumers, but also brings some hidden dangers and concerns.
Some time ago, some media broke the news that “100,000 B boards flowed into the market”, which caused an uproar and became a hot topic in the market. A newspaper said: “Some manufacturers are very angry after hearing this rumor.” And scrambling to clarify that they have absolutely nothing to do with board B. But this is suspicious: since it has nothing to do with yourself, why should we be “angry”? Will this make people think that there is no silver here?
But it doesn’t matter anymore, because consumers only need to know the facts, and they don’t need to know much about the tricks behind the facts. In short, protect your investment, and be careful of the B board is always right!
Some people think that B board is easy to identify, just count the bright spots, which is actually a misunderstanding. The reason why B-class board is unqualified is not only because of bright spots, but also because it has defects in many aspects such as color and brightness, but it is not easy for ordinary consumers to judge without professional standards. Naming Nokia Test with the help of some professional test tools can play some roles, but it is best to find a knowledgeable friend for reference (I’m afraid most ordinary consumers don’t know how to use and judge this test tool); Moreover, for the sake of our own interests, we should try our best to choose well-known brands with good reputation.
Choose products according to their uses.
If you have successfully bypassed the trap of B board, congratulations! However, even in grade A products, there are advantages and disadvantages. How should we choose? Although manufacturers have concocted many concepts, how many are actually useful to us?
Therefore, before buying a monitor, you should first find out what you mainly want to do with it. For example, writers hope that the text on the display is sharp and the characters are clear, and occasionally watch videos and play games to relax; Violent gamers emphasize color gradation and saturation, brightness, contrast, and response time. At this time, the best choice is actually a CRT monitor. If you must choose a liquid crystal display, you should choose a product with excellent color performance of 12ms (8ms is said to have good game performance, but now it’s just the hype of the manufacturer).
It is more clear to decide the purpose before choosing the product, such as whether you focus on color or brightness contrast; Heavy response time or environmental performance; Emphasis on technical features or overall design …
It should be noted that although the selection may be biased, it does not mean that other performance indicators are not important. Some brands may overemphasize the characteristics of a certain aspect, which may be a manifestation of their lack of confidence in their comprehensive performance.
Look at the main indicators one by one
For workshop-style factories, it is not difficult to save a LCD, but for consumers, it is not easy to choose a LCD. I’m afraid it’s too difficult to study many indicators in a short time. So here are a few simple parameters for your reference when purchasing.
colour
As a display, as the name implies, “display” is its bounden duty. We hope to have a perfect display, then it should be able to show colors in the best effect. Strictly speaking, the color of LCD can’t be compared with CRT, but for less demanding consumers, LCD with excellent color expression is enough.
There is no fair criterion for color performance (some people may say: isn’t it the number of colors nominally supported? If it’s that simple … alas, all the products are actually similar, and I don’t need to talk nonsense here), mainly by naked eye observation. So it’s helpful to walk around and compare different brands and models. Everyone has different likes and dislikes of colors, so it’s OK to choose one that looks more comfortable for you. According to the author’s understanding to professional media reporters, the color of Samsung LCD is quite good.
Brightness contrast
As we all know, brightness is an important indicator of LCD. However, in the manual, the brightness and contrast data we found can’t show the whole performance of the product, because the brighter product is not necessarily a better product, and whether the brightness is uniform is the key, which can’t be found in the product specification. Similarly, the judgment of this performance depends more on our naked eyes. Generally speaking, displays with better quality have intelligent functions, which can automatically adjust images to achieve the best brightness and contrast. For example, Samsung’s “MagicBright” technology and LG’s Lightview all have such functions. Take Samsung 710V as an example, its brightness reaches 290 lumens, which is outstanding among similar products.
Response time
From 16ms to 12ms, and then to 8ms in hot speculation, the response time of LCD has attracted much attention. For liquid crystal displays, the shorter the response time, the less the “smear” phenomenon, but while the performance is improved, we are also concerned about whether the shortening of the response time will cause loss to the image quality. When 16ms became a thing of the past, the relevant manufacturers finally admitted this.
Consumers’ eyes are discerning. With the technological progress and competition upgrading, the improvement of response time will be less and less at the expense of picture quality. Although the truth came a little late, it was a good thing for consumers. 8ms technology was first proposed by Samsung, but BenQ was the first to launch the 8ms prototype. Moreover, BenQ and Youpai chased each other on 8ms, which became a “landscape” of the market. However, at present, 8ms products are not really listed on the market. Although prototypes can be seen in some markets, it is too far away to solve the thirst.
