1, select LCD or DLP
When you buy, the salesperson will ask you is to choose the LCD projector or DLP projector? At this point you may be up a gum tree? In the end choose a good? Which are good? In fact, both in the home have their own advantages in the projector; DLP is a new projection technology, LCD projection technology tradition. Compare old and new technology, of course, new technology slightly better than the old technology, as "a chip" on the performance in a compact and portable, true and accurate image reproduction, image layering is good, excellent black effect. Of course, the traditional LCD projector technology is relatively mature, with high light efficiency, beautiful color, saturation and good technical superiority can not be replaced. However, to remind the user one, in the same resolution, DLP technology, the projector's LCD technology, the price is almost double.
2, the brightness and contrast
many friends have asked to buy the projector, is not the brightness as high as possible? In actual fact, if you are buying business machines, of course, the higher the brightness the better, because the business use of the environment area, and strong light, which is not the same with the home environment. For individual users, too bright is not necessarily a good thing. Because individual users of the use of the area is much smaller, better interior shading, projection screen is too bright, but people feel dazzling, and even eye damage. The general area of home users use of the environment, if 20 to 50 square meters, the general brightness of the projector home at 800 lumens to 1200 lumens or so. On the contrast, that is, the higher the better. The higher contrast, sharper images eye-catching, bright vivid colors, details to show good results. Performance in contrast, DLP has the advantage over LCD.
3, resolution and aspect ratio
Buy home projectors, of course, is to buy affordable and models, so be sure to know what kind of parameters linked with the price. Following the resolution just like we said the price of the projector has a great relationship, the higher the resolution, the clearer the image projector, of course, the higher the price. From a long-term perspective, if economic conditions permit, it is best to buy the physical resolution XGA projector, which displays the effect is clearer, bright. But for the home, the current SVGA projector can meet the needs of most people. Is worth a reminder to purchase the projector, be sure to distinguish between the good standard resolution and maximum resolution, standard resolution is the normal display output when the projector resolution, while the maximum resolution supported is outside the projector maximum resolution of the device, meaning that if the purchase of a maximum resolution of 1024 × 768, while the true resolution of 800 × 600 projector, the picture of the show is 800 × 600.
In addition, the projector when you buy be sure to ask, the real projection projector or a 16:9 ratio is 4:3, and now most of the DVD film source is a "variable-type wide-screen 16:9" mode, followed by HD standard 16:9 aspect ratio television screen, home projector or a 16:9 ratio will be the trend with the development. With the micro projector features become more perfect, but also into more and more families.
