Is the so-called "turnip greens, all have love." Face Projector 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, for more specialized testing is powerless against this problem, the following detailed description of how this will be the key to performance test the projector, and ultimately determine the purchase of products. .
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 light, may request the appropriate business open tube, close to their real use environment. Business environment is generally provided by the chamber, so that the brightness of the natural look is enough, 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 features of the 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 frequently used presentation content. 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, whether a short-focus lens, can cast the same distance on a greater importance in the picture. .
Try questioning and after-sales person 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 to demonstrate from the computer, then flip, simulation Mouse The essential functions. Of course, handle the remote control is also very important, it also requires buyers to experience in person. .
In addition it should be noted 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. .
The second is the product of the after-sale warranty want to ask. Chose this time to ask those in the content, on the one hand because it is every buyers must know before buying, clearly, to avoid future disputes, on the other hand, through this period of time for the projector to work, it continuous use up to a certain time, and then further observation. Although half a year bulb warranty and two years warranty is basically industry standard machine, but some brands offer a longer warranty period, or provide on-site, spare machine and other personal services.
