I now give supporting the return of weapons, hoping to help. Before buying the projector must be in a better understanding of all aspects of projector performance and conditions market, etc. Also, some of the consumers themselves should also be considered as the use of space, size, use of the environment is good or bad, the installation and the projector's resolution and brightness requirements, and so the situation must be taken into account. This is not going to be tricky business, and you can buy a real bed of roses on the projector.
The following is a brief summary for you to buy the projector must take into account several aspects, with a glance. 1, Volume Weight: purchasing a projector The first of these factors should be considered. If the projector is used in the office rooms, the weight can not be considered, but if you want to use the projector to get as many times shown, most of the time, had to carry the projector, then the largest weight is the first consideration. 2, scan range: According to the specifications included in the range of horizontal scan rate of exploration, a selection of high, medium and low frequency, calculate the three frequencies corresponding to the resolution image. Check the projector in the three decisions can be displayed properly.

Signal generator with a computer or a projector can produce the highest resolution signal white graphics, with the smallest characters in the screen graphics are clear. video bandwidth, such as lack of the machine side, the screen shows a stronger lines, while lines vertical false detail, the dark image. 5 Image quality: projection screen quality is essential if the projector of the purchase consideration. One excellent image quality of the projector, the screen should be structured, such as black should be black, not dark gray or even "Blue Black" (in particular, show that when hair or other materials), display text must be clear and sharp. 6 of the installation: Installation type of projector is thrown on the table, rear projection table-type, ceiling rear. It is the public vote is the projector on one side, the projection is the same screen with the public at both ends. If the temporary use, select the type of table turns, this approach influenced by environmental light, disorderly arrangement. As with the fixed mode option roof.
If space larger, coordinated civil settlements from time to time, choose the best overall projection methods, such as less space, optional method refraction rear. 7, Resolution: Resolution of the projector is connected to the computer inseparable. To help you buy the projector projects the most perfect demonstration effect occurs, we suggest that you are buying the projector and screen resolution of the device in the same resolution, in order to achieve a perfect result. 8, Brightness: Average users the choice of projector, the main room in the brightness of the eyes. the brightness of the projector is one of the key performance indicators, has a relationship direct the viewer is able to clearly identify the graphics on the screen text. Currently, the mainstream market spotlight shine on all products in 2000 to 3000 lumens or more. 9 of the bulb: As the only consumer projector supplies expected, the projector should consider when choosing a major factor. Projector now is widely used metal halide lamp, lamp UHE, U HP These three light bulbs.
