The 3D arrives with force to the domestic projectors of home theater

Home cinema, that is, the ability of the viewer to watch movies in their own home with a sound and image quality, beyond the size of the screen, which have little to envy commercial theaters, is reaching levels of acceptance Growing. The leisure time shared with family or friends, and the convenience of not depending on schedules or paying an entrance, begin to be very attractive aspects.

Today’s often large TVs provide high-definition picture quality Hier entlang, and sound amplifiers, capable of delivering a multi-channel soundtrack, complete the show. But for those who miss the “cinema effect”, there is an even more interesting alternative: the projectors, the technology of which has reached a high level. With them it is possible to project video images achieving a very large screen size, and still very luminous.

Many moviegoers enjoy all this technology at home, with not too high investments. But the technique in commercial theaters also advances , and perhaps to attract more audience to theaters, film engineers never cease to innovate in areas such as image or sound. One of the new contributions that have made furor during the last times have been the films in 3D. Spectators can appreciate this effect thanks to special polarized glasses, far removed from the old colored anaglyphs.

As it could not be otherwise, the commercialization of 3D films in the domestic sector was not slow in occurring, for which it has required a new technological leap in our televisions. Many of the new mid-range and high-end devices are already equipped with everything you need to present high-quality 3D movies. But what about the lovers of the projectors?

3D visualization technology applied to the world of projectors has taken a little longer to be available, and often at high prices. Things, however, are already changing. A new generation of 3D-compatible projectors is reaching out to specialist retailers, and it’s becoming an option to take full account.

The 3D projector is naturally compatible with all types of image, with the addition of that new technology. Nevertheless, there are different types of equipment on the market. There are 3D Full HD, 3D HD Ready and even low cost, equipped with HDMI connections that are capable of handling the flow of data that involves three-dimensional projection. In addition, 3D projectors can be subdivided into assets and liabilities, depending on the type of glasses they use. Their prices fluctuate greatly, from little more than 300 euros to 6,000 euros or more, depending on the type of optics, output resolution, brightness, etc.

The most complete 3D projectors have a resolution of 1920 by 1200, ie compatible with Full HD, and a lighting system for LCD or DLP, capable of brightness up to 6200 lumens and a contrast ratio of 6000: 1 or better. They are equipped with interchangeable lenses and can even be connected via Wifi to computer equipment. A recent technical addition, the interface for 4K images, will surely prevail over time. They can also carry 2D to 3D image converters.

In addition to cinema, 3D projectors are ideal for displaying large format images of our computer games, looking for maximum immersion for the player, or for business and educational activities.

The projectors are not intended for continuous use for many hours and their lamps usually last between 2,000 and 4,000 hours, depending on several factors. However, during the time that we make them work, they will provide a sensation of cinematic vision incomparable. With 3D, now, we can enjoy at home the same thing that we could find in a commercial cinema. Especially if we make our own popcorn.
