<br> Home-use projectors for home users for now, still there are some in the use and purchase needs noted, after all, the projector to the present, the structure is quite complex and still in daily use as a precision instrument, not .an everyday household appliance, this is going to buy a projector friends or very important. First purchase household machine friends to distinguish projector is parallel, primarily because household machine market, due to market demand, and the price is quite high, with shipments and trade .channels is less than the poor, the failure to meet the basic criteria for profits is to lose money. Faced with this situation, market flood household machine parallel available to describe even some seemingly very formal businesses, selling home machine might not be mainstream, but .some manufacturers face household machine market downturn, often on channels and distributors sell the parallel conduct is turn a blind eye to eye. Faced with this kind of flower, consumers need to Polish your own eyes, check whether the projector, and mainstream products similar in .General, just three yards in one sort of thing, most notably in the purchase after the first time to the manufacturer's customer service queries is a bit, and finally you sure whether they buy into the mainstream. At the same time also to remind us not .to corrupt a two hundred block xiaobianyi or one or two worthless giveaways carelessness to parallel imports, as the projector warranty and after-sale maintenance is very important, unless you are very familiar with the projector industries, and dealer relations are very good, or or .not to recommend everyone buy parallel projector. Get rid of the problem of parallel imports, the use of the projector in the family, as well as maintaining the same important, after all, a finite service life of projectors, including the lamp more expensive consumables ., thousands of hours of life is a daily limit, and if used improperly, as long as hundreds of hours of life may make it possible to scrap, and the maintenance cost is also very exaggerated, it is for personal purchases, or a small fee .. First of all, the best choice for their own household projector, lifting the aim is to avoid the projector in the non-captive use encounter violent shaking, hitting, and so on not necessary. Because the projector in the operational requirements of the stability .is high, the violent shaking the lamp life sharply reduce even spot scrap. Even if an exception is not caught, when using the projector are also need to adjust the angle of the projector, it is for home users is very troublesome thing while lifting can .avoid the above two cases, do of the post will be ready to use, very convenient. At the same time the family environment is also very important, many of my friends layout choice home theater room, most will choose a room without Windows, so .you don't have too many consider light on impact of projection screens, at the same time, due to the limited number of rooms in the design, so most of the rooms in 15 meters. Such a closed environment for the projector of the drop .shadow effect is very good, but if you take into account the life of the projector, then this design is somewhat inappropriate. Projector brightness in order to get enough, the temperature of the lamp are very high, thousands of degrees is no exaggeration, so .heat is the most important component of the projector, and to ensure that the cooling system to work properly, the projector will also need a rapid flow of air to the environment, a closed room although may not cause the projector to overheat, but will keep .the room temperature rise, treble, so while the image quality is very important, but still recommended you choose to have Windows and ventilation more convenient use of the site, as long as the curtain down something, you can reach the projector usage requirements, no .need for the pursuit of fully closed space and affect the use of oil organic. A projector with ordinary household appliances the biggest difference is that, in General only use electrical appliances bought back on the line, lazy, no clear, generally not bad luck, .the use of 1978 full not a problem. While the projector is a very sophisticated device, use the time if you are unable to develop good habits, it is possible late input would let people's pain, more likely to directly make projector scrap. When buying .a projector, you should ask the dealer on the projector's post-sales issues generally present the projector as long as is not a very serious problem, the dealer can resolve most affected by the problem, if not, then most of the higher units can also .be resolved, but note that the projector repair time, once the serious problems need to be sent up one level after sale or even return to factory, then at least a ten day and a half months to fix the problem, which means that we may ., however, available inorganic relatively depressed in a matter, so whether you want to provide an alternate machine is also a very real problem. Then there is on the back of the maintenance and upkeep of the projector is fine, needs regular cleaning, light bulb .as consumables may not regular will need to be replaced, for knowledge about the projector not more personal users who prefer to be handed over to experienced sellers. While vendors are also committed to provide, within one year of free service several times, but if you .'re very brisk sees a type, but not required, then this time JS mostly does the initiative, this time will be our own to fight for their own interests. We run some projectors use may result in serious consequences of bad habits: 1 direct .power off, shutdown, and many of my friends are the machine direct power-off, do so on the one hand, to prevent electrical accidents, on the other hand is to save a certain amount of power, this is now the State advocates of .savings is directly related to environmental protection. But as the projector, such practices are not the right place, because the projector internal temperature is very high, so the projector needs to shut down after a period of cooling time to prevent the projector lamp failure. .This time if the direct power off, then no power failure protection of projectors can cause the lamp damage, explosion (now technology is mature, the chances are not great) accelerated aging projector pieces. 2. plug any signal source signal source such as a .USB, VGA, DVI, HDMI, and so on, although the process is very mature, generally we plug will not appear, even when buying a projector, projector businessmen in time for customer presentations directly plug, such practices often make people mistaken for Plug .does not have any problems. However the actual situation is not quite so that businesses can plug that is because as the Demo prototype if problems occur, then companies will be responsible for repair or compensation, can be said that the businesses themselves without any loss. .But if you are an individual purchase, plug the interface once burned, which often manufacturers even if not for a fee, you need to repair the machine back manufacturers, we completely outweigh, instead of the boring, time than now to develop good habits. .3, the signal cable is not too long in General, a quality of signal lines are in the range of 20 meters, more than the distance signal will be affected, household projection is certainly not saying that you want to enjoy the top, at least ., is the level of audio quality with fever. Then the signal attenuation is unbearable situation, and the general solution included in middle and signal amplifier, either reduce the signal line length. There may be some friends will think at home with the projector, the .signal cable is not possible to have so long, but I have a friend to the signal cable from the room on the eighth floor, received 11 floor projection experience can tell you not only appear, often very extreme. After the match, you may wish .to projector look invoices, as manufacturers after-sales service of slip, if there are no invoices, no LUN how manufacturers are not going to provide warranty services, of which some merchants will invoice, but will also appear as fake invoice, invoice no written .projector model number, serial number without the projector, so that after buying a projector, may wish to invoice to seriously, while some businesses also have their own warranty chapter, this chapter of the invoice, businesses will provide you with the service commitments, if .invoices no chapter, businesses will provide fee-based service, it Center might have a few hundred dollars the price gap, so we pay for it, be sure to carefully check the contents of the invoice. About gifts, although not present the projector market .like past profits, some businesses in order to be shipped, often provide some such as curtains, bags, tripods, etc like gifts in order to increase the product price, at the same time you can attract some love your rendezvous of total xiaobianyi consumers to .purchase their own fear of the product. But we must remember that remark out the sheep wool, these so-called premium we all pay the fact or, where such as complimentary screen most of the quality, the price is not very expensive for the average .home user, the use is very limited, gain even further than just brush up, however the white wall, or work very rough, use half a year after the screen starts to deformation, very out wrinkles. Everyone buying a projector to note the time .of the lamp projector, projector businessmen and monitor merchants will use means: sell samples, and the monitor are removed now sell vary, most in business projector projectors use for some time on Boxing repackaging, at the time of sale to sell the new machine, .the projector while it is not in use, but the lamp life may not be guaranteed, so that when buying a projector to the commissioning of the bulb when viewing the projector to avoid using time for the business of prototype bought single. Finally, we advise .you to purchase any product, when it is best not to speak, we must first look to the website to purchase a number of product sales prices, whether there are activities and giveaways, and bulb warranty time number, if once encountered by businesses in transition ., and mind, then may wish to note the model number to find out and then go home to purchase, as the drive to a second slower, shopping should adhere to similar principles, not impulse, don't be confused by the recommender's recommended, .the performance of the product are made sure then according to their actual use will need to select the final purchase. <br>.
