<br> Buy home projector, many consumers are very concerned about the overhead of basic parameters: for example, resolution, brightness, contrast, etc. These parameters can be somewhat up characterization of projectors. Through resolution parameter selection of products is also a very .simple, easy and practical way. <br> <br> Home projector mainstream resolution is actually only 720p and 1080p two types. Both types of products of the most important difference in screen xinidu - no doubt more exquisite 1080p picture and more suitable for large .screen projection. Typically, if the projection screen size is 60-80 inches, 720p projector has to demonstrate very good results. But if the screen size grows to more than 100 inches, select 1080p projector is and necessary. <br> <br> .And the resolution of a factor was the product price. 720 p home projector prices start from more than 8000, there are enough of the TENs. Most of these products are mainly concentrated in 10000-15000 price point. While the 1080p projector price will be .high on many, at least in 20000 million price. This price factor is what determines consumers to buy products. <br> <br> Home projector brightness target very uniform. Most products have a brightness of 1000 lumens. This value is to be able .to meet the display bright screen, and in the indoor environment to control the screen brightness for and consumer of the eyes, do not cause a "dazzling" feeling. Buy home projectors don't select high brightness of products: high-brightness led will .be on the eyes do not harm. <br> <br> For video product contrast argument exception. Because it is in a certain sense, to indicate that the product to the smallest detail display capability. In theory, the higher the contrast ratio the .better. But consumers need to distinguish between businesses give the true meaning of the contrast value. The industry has a native contrast ratio concept, refers to not take advantage of any aperture, technical means can get maximum value. But another contrast values are in the .dynamic aperture with the test. The contrast between the numeric value can be one or two orders of magnitude, consumers must distinguish between merchants and contrast data which is to distinguish the product. <br> <br> In addition to the above the main parameters .that configure the interface is also one of the consumers concerned about content. From the convenience of perspective, the interface is, of course, the more full, also the better. But too many interface configuration will increase the cost for manufacturers of consumers is not .necessarily the "useful". Most application conditions, household projector should at least have a HDMI or DVI interface, a color interface, as well as a VGA connector. Because all three of the very high frequency of use. <br> <br> .The above simple introduces a selection of home-use projectors that need attention. As one of the words may not be accurate, the only hope for consumers, in particular the new consumers in the new entry. However, these technical factors still cannot decide the .merits of a product, those who cannot see details tend to be products "at the core of success". Therefore, consumers' home projector choice should be the ultimate in picture quality as the core, at the same time reference above these technical factors, ."Godspeed" has been reached. <br>.
