subject: Industry Tip: Home Projector To "see" Parameter Learning High [print this page] Buy home Projector Many consumers are very concerned about Projection Machine's basic parameters: for example, resolution, brightness, contrast and so on. These parameters can be characterized to some extent Projector Merits of the product. By distinguishing parameter selection of products is a very simple and easy to utility to approach.
Mainstream resolution home projector in fact only two types of 720p and 1080p. The main difference between these two types of product sophistication on the screen?? 1080p picture is undoubtedly more delicate and more suited to large-sized projection screen. Typically, if the projection screen size is 60-80 inches, 720p projector has been able to demonstrate very good results. But if the screen size increased to 100 inches or more, select 1080p projector and it becomes necessary.
Associated with the resolution of a factor is price. 720p home projector prices start from more than 8,000, enough to have a few million. Most prices in 10000-15000 yuan mainly price. The comparison, 1080p projector prices high on a lot of must, at least in the price of around 200 million yuan. This price factor is decided what products consumers buy one of the reasons.
Home projector brightness index is uniform. Most products with 1000 lumens of brightness. This value not only to meet the needs of the screen shows bright, they can control the screen brightness indoor environment for the consumer's eyes, not cause "glare" feeling. Never select the home buying high-brightness projector products: high brightness will result in no small eye damage.
Contrast parameters for video products is extremely important. Because it can be expressed in a certain sense the most minute details of the product display capabilities. Theoretically, the higher the better contrast. But consumers need to distinguish between business values given in the true meaning of the contrast. The industry has a native contrast ratio, means the aperture does not use any other Technology Means to get the maximum contrast value. The other contrast is the value of the dynamic aperture in conjunction with the test to get. This difference between the two contrast values can be one or two orders of magnitude, so consumers must distinguish between the contrast of the data business which in the end is to distinguish the merits of products.
Addition to the above these main parameters, interface configuration is also one of the elements of concern to consumers. From the application point of view of convenience, the interface is of course the more the more complete, the better the. But too much factory interface configuration will increase the cost to consumers is not a "useful" spending. Under most applications, home projector should at least have a HDMI or DV I interface, a color interface and a VGA interfaces. Because these three very high frequency of use.
A bit more than a brief selection of home projector needs attention. As one of the words may not be accurate, only hope for consumers, especially the new entry of new consumers be helpful. However, these technical factors still can not decide the merits of a product, those who can not see the details of the products often become the "success" of the core reasons. Therefore, the consumer choice for home projector or the screen should be final quality of the core, also refer to these technical factors in the above, has reached the "instant success" effect.
