What Is A Projector?

A home projector screen is a great alternative to a TV. What is this technology capable of? The video projector will delight the viewer with a truly large image: the diagonal here is measured in meters, while the device itself has more compact (compared to TV) dimensions.

Home projectors allow you to indulge yourself with your favorite movies on the big screen, while a compact office projector will give you the opportunity to make video presentations (all you need is a flat white wall or screen). Projectors for a school or university will also provide invaluable assistance in the educational process: watching educational and scientific films will make learning not only effective but also interesting. When choosing a projector for a room, you should pay attention to such a feature as the device's resolution (the higher it is, the better the picture will be). In particular, the HDMI projector guarantees a high-resolution image. The brightness and contrast parameters of the image in a dark and bright room are also important.

Home Theater Projectors

Home cinema, also called home theater, is a system, which advantages are well-known to every video fan. And the use of a device such as a multimedia projector in such a system will turn home movie shows into an even more exciting and spectacular event. If you have long dreamed of adding a home theater projector to your collection of digital equipment, consider the following classification of such equipment depending on the type of matrix used.

1. LCD projector. It is a device with a liquid crystal matrix that creates an image using a prism.
   
2. DLP, a digital projector, that uses micromirror technology. Such a multifunctional cinema projector has three separate DMD matrices for each color.
   

A unique 4K projector with a resolution of about 4,000 horizontal pixels gives the viewer the quality of the picture, as close as possible to the one in a cinema.

3D projectors

Cinema in 3D has become even more within reach because, nowadays, it is quite possible to buy a three-dimensional projector for the home for a reasonable price.

A Full HD 3D projector is a revolutionary device that allows you to create a 3D cinema at home or in the office (and if you wish, you can use such video equipment both at home and at work because it is small and easy to transport). Such a Full HD projector involves the use of 3D glasses and has the function of converting a video image from 2D to 3D without a source that supports a three-dimensional format.

At the same time, a Full HD projector can support one of two 3D projection technologies — active or passive. In the first case, the device broadcasts the image for the left and right eyes in turn. The second technology of double projection superimposes a pair of stereoscopic half-frames on top of each other. read other articles
