Projector
Store, business was significantly improved. In a time when consumers buy the projector, I also went up and consumers and sales personnel in the exchange, found that consumers on how to choose a projector in a confused state in general, while in the purchase of what issues should be noted also in the dark state.
Now, the editor in conjunction with their personal experience and work experience for ordinary consumers to use a few suggestions to help you guard against profiteers, to buy goods bed of roses.
First of all, to understand some basic parameters. In the projector, the important parameters include the brightness (in lumens), resolution, contrast, noise, weight and other aspects. Which home projector 1000 lumens of brightness is generally about entertainment projector 2000 lumens brightness are all about. Select the family to use, it is recommended to choose between brightness 800-2500 lumens brightness is too low, watch the picture is not clear; brightness too, has some damage to the eyes. Of course, if the projector is selected, then business will have to education is another matter. General 2000 lumen projector is about 20 square meters suitable for a small meeting room, while about 30 square meters of meeting rooms requires the projector to 2500 lumens of brightness, as more than 50 square meters of meeting rooms or classrooms, the brightness is only 3000 lumens above to achieve satisfactory results.
The resolution, now the mainstream market, the resolution of the projector probably be divided into four different levels, namely 800 600,1024 768,720 p, 1080p, of which 800 600,1024 768 in the Business Education the application of more projectors, while 720p and 1080p high-definition home projector is the available parameters.
Contrast, the DLP display technology to business education and entertainment projector projectors are about 2000:1 contrast ratio, while the 720p projector contrast is generally more common in 5000:1,1080 p over the 10,000:1 contrast ratio the more high, the more outstanding picture quality.
Projector noise is generally present in 20dB-35dB, and the average business projector body more light, heat dissipation is not very convenient, on-chip high noise value, while the high-definition home projector body large, heat to facilitate , generally in the 20dB noise around.
Addition, the current projector display technology can be divided into LCD, DLP, 3LCD, etc. 3. In contrast, DLP in the display text, tables, when the effect is more remarkable, but in the choice of the projector when the proposed home or to use LCD, 3LCD projector display technology. LCD, 3LCD image quality in color display a high degree of color reduction, in the family use of the inherent advantages.
Understand the above terms, the in and the process of communication between sales staff will be able to fully grasp the right to speak, listen profiteers also reduced the chances and deceived.
Understanding of the basic parameters finished, we began to find the right product on the market has. Books on the gap between knowledge and reality is still very large, then how can we prevent it being black heart of the dealers on wild speculations? I believe that the following aspects need attention.
First of all, is to investigate the situation himself to purchase the product price. Product knowledge, you can query Zhongguancun online portfolio to the satisfaction of a commodity. Select finished goods, the paying particular attention to commodity prices. In order to price more preparation, the best choice to consult several different businesses, so that pretty well.
Secondly, in the purchase process, often by businesses to sell goods without cash, or a performance of a product better than the original product, and the price is similar, and thus also a product recommendation. Encountered such a situation, if not on the sales of products recommended do not know, it is best to understand the real situation carefully after considering doing. Because there are many bad business to use this opportunity to consumers on wild speculations.
