subject: 2009 Turn Of The Year: Buy The Projector Need Law [print this page] Turn of the year, in the face of many Projector Brand promotion, profit-sharing initiatives such as, I believe many of my friends to buy in the head of the projector. The face of the projector on the market many brands, many models, I believe most people buy before the projector will use their own methods of understanding, such as online searching, telephone consultation or ask a friend recommended. However, a few machines in determining, after finalizing finalizing a very nerve-racking. The reason is the candidate machine performance parameters of several units similar to the price differences are small, is a quandary. Buyers generally do not have the professional knowledge of projectors, that do nothing more for the professional test for this problem, the following article will describe in detail how to test key performance projectors, and ultimately determine the purchase of products. .
Need a Law: Test performance simulation environment
Buy the projector, the business will generally provide a very good test environment for you to try, which often give buyers a false impression. As a business, which of course is understandable, but as a user can not because "the surface looks good," the hasty decision. Simulate the real use of the environment so that businesses do not use the standard provided by the environment, which will be used according to their projectors after the environment layout. .
(1) brightness of the environment if the buyer than the actual use of bright, may request the appropriate business open tube, close to their real use environment. Provide general business environment for the darkroom, so it seemed natural light is sufficient, and a variety of colors will appear very bright. For small text, then do not have any problems. But once a certain light interference problems will be presented. .
(2) energy saving mode because of cost considerations, many users will actually use the projector in energy saving mode, many projector bulb life in energy-saving mode is often extended to twice the original. Because of different energy-saving mode for the projector's brightness decay is not the same, so users need to test the energy saving mode, the brightness is acceptable. .
(3) demo content demo content businesses often provide comprehensive, image and text each other a certain percentage, of course, does not rule out a bad business because of the different characteristics of projector and "omit" some kind of test picture. Even with the contents of a comprehensive and professional, I recommend that you purchase to bring their own demonstration, the projector is usually the most frequent use of the content of the presentation. For example, in business black and white text provided a good test result does not mean that in their own pink with black characters on the same clear and PowerPoint documents. .
(4) demonstrates that the conventional mode of presentation, standard, cinema, game modes. In fact, there is no need to test all the patterns again, because the actual use to which typically use only one or two. Such as text display-based user may wish to only test the standard and presentation mode, home theater mode is bound to be tested. .
(5) wide-angle performance of the average user if the environment is less restrictive, you can not consider this factor. But the use of a shorter projection distance of occasions, it has a short focal Shot , Can cast the same distance on the bigger picture abnormal important. .
Need rule 2: try asking in person next sale
Reason to try their hand, because many functions and operations that must be felt, which for ease of use and human testing of its design is essential. If the entire presentation by the merchant to complete the process, these details may be omitted. For example, some models of the remote sensing rather slow, which in the long-term use will make people very angry. Need from Computer Presentation, then flip, analog functions on the essential mouse. Of course, handle the remote control is also very important, it also requires buyers to experience in person. .
Also we should note that many so-called "smart regulation", only to re-search signal source and adjust the frequency phase, and some models can even be automatic keystone correction auto-focus and brightness contrast adjustment, in advocating for a number of manufacturers regulatory functions with fast time intelligence, we must keep a clear head, try the actual results themselves.
