So, we will try to cover the main types of projectors on which you should stay, depending on which room you need to equip, be it a home lounge, classroom, office, meeting room, exhibition or assembly hall, concert hall, museum or movie theater.

Projectors for small classrooms, classrooms, small conference rooms.

For small classrooms and classrooms that do not require particularly vivid images, portable projectors are best suited. They are compact and lightweight (from 2.5 to 4 kg), so that they are conveniently transferred from the audience to the audience and easy to install before the class begins. They will be the cheapest of the many proposals. The built-in zoom lens allows you to adjust the image size according to the area of ​​the wall or board. In this case, you should pay attention to the speed on and off, as well as energy-saving features (automatic brightness reduction, image shutdown). In pursuit of savings, it is worth considering the fact that, as a rule, cheap portable projectors use a short-lived lamp, which, if used frequently, uses the projector very quickly fails. The most annoying moment that lamp replacement will cost about 80% of the cost of the projector itself. Therefore, you should still consider the option a little more expensive, but with a long operating time and warranty period. It is also necessary to take into account the location of the projector so that there are no foreign objects in the gap between the projected surface (distance approximately equal to 2-3 meters). When avoiding interference does not work, you should consider more expensive projectors with a short focus.
Short-focus and ultra-short-focus projectors are ideal for small rooms with limited space. Such models can be installed in close proximity to a wall, screen or digital whiteboard. At the same time, they provide a clear image with a diameter of 2 meters or even more.
If you look at a screen or an interactive whiteboard on a mobile stand with such a projector, you can easily move the finished installation from one room to another within the same floor.
Do not neglect such criteria as energy-saving functions (automatic dimming, image shutdown); the presence of such functions will help reduce operating costs. A built-in zoom lens and features such as keystone correction provide projection of sharp, sharp images that are exactly the size of the board or wall. Wi-Fi-enabled projectors can be connected to a laptop or tablet without cables.
An excellent solution for business people who hold a large number of field presentations at the customer will be a pocket-type projector (mini projector). It will not be difficult to carry with them. The projector literally fits in the palm of your hand. The brightness and size of the projection will be sufficient for conducting presentations for a small public. Well, as a nice addition to long trips, this rojector can be used to watch movies in the evenings from a laptop or even a phone.

Projectors for large audiences and halls

If you equip a large audience, an installation projector will be an excellent option. The brightness of such projectors starts from 4,000. Such power allows you to display images without even closing the windows. Thanks to interchangeable lenses, a stationary projector can be installed anywhere in the audience, and the correction of keystone distortion and lens shift provides a realistic image with precise proportions. As a rule, such projectors are installed under the ceiling on special brackets, which allows to avoid interference with the projection. If you have the task of installing in a building under construction, or the room is undergoing a major overhaul, it is worth considering an option with a different execution of the projector installation. Sliding Ceilings,
Bright conference lights are required for meeting rooms and spacious conference rooms, the image of which is clearly visible even in daylight. In such cases, the best choice is a powerful ceiling-mounted installation projector with a brightness of 4,000 lumens or more. With a wide range of interchangeable lenses, the proportions of the projected image can be adjusted to the projector precisely according to the size of the room. In very large rooms, you can use not one projector, but two or more: the function of combining the edges will create one huge picture from several images. If the projector is supposed to be used frequently and for a long time, it is recommended to consider laser models: they are economical and practically maintenance-free.

Projectors for museums and exhibitions

Museums, art galleries and other public spaces require projectors for visualization and modeling. Interchangeable shift lenses provide a large image with precise proportions, regardless of where the projector is installed. Among other advantages, laser projectors are distinguished by a long service life, and they do not lose brightness over time, require virtually no maintenance and additional costs. In addition, these projectors are equipped with the function of combining edges, which combines projections from two or more devices into one huge high-resolution image, and the technology of image deformation opens up broad creative possibilities, providing a projection on curved and uneven surfaces.

Home Cinema Projectors

Such projectors provide the best image quality in darkened living rooms, basements and special rooms. The zoom lens allows you to precisely adjust the image according to the size of the room. As a rule, all home theater projectors support Full HD resolution, and some 4K format, which ensures image quality at the level of professional movie projectors. Resolution technology will improve the quality of Blu-ray ™ and DVD movies to 4K, and the Reality Creation feature will do the same for 3D video. Motion flow technology eliminates blur, providing a consistently clear image. New models of projectors support even movies shot in HDR (high dynamic range mode) and characterized by particularly high contrast, as well as an increased number of brightness levels. For convenience, the settings you set can be saved in order to then recall them from memory: this way you can easily create your own viewing modes for different filmmakers. The pleasant moment will be that such projectors are practically silent. It is worth being prepared for the fact that during the days of football broadcasts your friends will gather under any pretext.

 Cinema Projectors

Powerful digital cinema projectors should provide image brightness from 9,000 to 30,000 lumens. Digital 4K film projectors have twice the resolution than older 2K models, which is more than four times higher than Full HD, so viewers won't see any pixilation even from the front rows. There are other features that improve image quality that you should pay attention to. For example, the SXRD optical hub in Sony models provides rich realistic colors and an unprecedented contrast ratio — up to 8,000: 1. Due to this, bright areas of the image look even brighter, and dark - deeper and richer. In some models, not one xenon light source is used, as in conventional film projectors, but a robust design of several high-pressure mercury lamps, which guarantees that even if one of the lamps fails, the film will not be interrupted. This design requires almost no maintenance and is less energy-consuming than xenon projectors, so you save on electricity.
