Use the projector is no longer confused Xiangjie Note – projectors, office equip
Said Projector Use, many people will think it has great differences with the TV. TV buying back power and TV signal line connection can be used directly, while the projector on the placement, distance, brightness and turned on the screen has a high debugging is required, if you choose, improper operation, projection screen out are difficult to achieve the best results, it is the ordinary consumer is very difficult to do.
How to choose a projector, using the environment to make the projector to achieve the best results, that is, the contents of this article describes. Here I Take home projector, for example, as we introduce some projector Caution.
Note Overhead Projector In the choice of home projectors, we must first determine their use of the environment. Projector projection screen in the process, the screen brightness of the final results obtained are closely related to ambient light and projection, which is due to the human eye perceived brightness projection effect their environment by the projector light and the projector fired up its own projection produced by interaction with light.
If the working environment where the projector light more strongly, then the 2500 lumens projector lamps to the projection screen on the role of the brightness effect, it is possible, and 2000 lumen projection lamp to the projection screen in the role of the brightness effect almost, which is As the projection screen in the relatively strong external light conditions, the projector lamp will light projected onto the screen in high-degree reflection Thus projection screen from the projector's light source in the real energy would be substantially reduced, as would screen brightness the human eye perceived effects of naturally decreases.
And general commercial machine is different from home projector in order to ensure the reduction of color and really show the contrast of brightness will remain at about 800 to 1500 lumens. Compared to commercial aircraft of more than 2,000 lumens brightness, the use of the best home projector shading conditions in a better room.
Attention away from the screen size and installation
Said the size of the projector, many people buy a projector that you want to get more than the TV screen, while the projector's projection distance will determine the size of the screen projection.
Projector projection size is generally 100 inches, 120 inches, 150 inches, due to the brightness limit, not suitable for projection of the bigger picture, and this is now on the market Projection screen Several dimensions. The most common size is 100 inches and 120 inches, this screen size the picture exhibited by the best.
Home projector more common desktops are two kinds of investment and the lifting is to vote, vote for the desktop is larger living room environment, while hoisting the adaptation direction is cast wider. General Projection confidential projection screen 100 inches, projection distance of at least 3 meters distance, if the use of smaller bedroom projector, we should look at prior measurement of the projection distance of the projector to select on the table, or lifting the .
In addition, we install the projector when the projector lens as far as possible is on the projection screen, which would allow the projector without the need for keystone correction project a perfect case of a rectangular screen, if you use trapezoidal correction will produce the picture projected by distortion. Now on the market are high-end home projector with a lens shift function, to a certain extent, solved the problem. Note that wire with
The connection process, the wire with the use of the projector plays a vital role. During use, in addition to being a computer projection signal interference, are also in the process of signal transmission encounter other interference, if not to interfere with a variety of possible excluded, then the output of the projector would certainly result in a large discount.
Projection to shield the signal transmission interference encountered in the process, which requires us to use to buy projector comes with the original signal cable, if users want better picture results, then we can also go to the market select high quality signal cable to make projector cable.
General, the more coarse signal cable diameter, then the projection of the output signal in the cable transmission of the lower attenuation, then the projection of the output signal the better the user to enjoy the projection effect is more clear and realistic. Of course, in self-projection connection cable, we must minimize the number of cable middle connector, after all, the more the number of joints, then projected the greater the attenuation the signal, then the output projection screen more prone to distortion.
In addition, when the projectors and video players require a longer cable to connect the words, projection signal in the transmission process may be more severe decay, so also may reduce the projector output. In order to avoid projection signal attenuation over long-distance transmission occurs after the phenomenon, so we installed when the projector so that we keep close with the players.
