How to choose a projector

Many families love to gather to enjoy your favorite movie.To make this process more comfortable and invented cinema house.

and if there is a movie theater, there must be a projector.In this review we will focus on how to choose the right projector.

First of all, pay attention to the company-creator of your chosen model.

most famous manufacturers of projectors

• Samsung.
• NEC.
• Toshiba.
• LG.
• Hitachi.

Prices for projectors

projector cost cinema varies over a fairly wide range (from a few hundred to several thousand dollars per unit).What caused such a significant variation of price proposals?

main criteria pricing projector

Lamp Settings

Comparing the proposed models and wondering how best to choose the projector, ensure that, as a fading light.Give preference should be the one that goes out gently, it will last longer than the light that goes off sharply.Remember also that the warranties regarding the life of the lamp should be recorded separately asIt ranked among the consumables.

Then read the following parameters:

average lifetime

This value for conventional models is 4-5 thousand hours.However, after 1-2 thousand hours of application, the lamp brightness becomes less intense.

Luminous flux and distance

Luminous flux - refers to the amount of light energy, the light source is distributed in all directions.The range of lumen output - is the distance at which this energy is transported.Normal setting -. 10-12 m

Brightness

Featured image perception in daylight in a light room give preference to the projector with a brightness of 2,500 lumens, less lit room - 1000 lumens, in a dark screening room - 750 Lumens.It is important to know that the brightness of the light flux in the central region than in its outer regions.

Contrast

This value indicates the ratio of the brightest points of illumination to image-light the darkest.In the data sheet it looks like this: 1500: 1 or 3000: 1.But, in fairness, it must be said that the characteristic of this does not matter much to the ordinary buyer.

uniformity of luminous flux

default value for a home projector is greater than 85%.

Resolution Image

This weighty in its meaning different characteristics for different types of projectors.

• FULL HD (1920x1080).This is the most expensive projectors, ensuring, at the same time, the highest quality image.The aspect ratio for parameters such permission 16: 9.
• SVGA (800 × 600) format 4: 3.It is not such an expensive option.
• XGA (1024 × 768), costs about as much as, and the aspect ratio the same - 4: 3.

Technologies manufacturing

DLP

The projector, perfect for home, the creation of the image is as follows: the light beam passes through the swivel six-color light wheel, is reflected from the moving mirror DMD-chip, and reaches the lens.This technology, the most in demand when creating a home theater projectors, providing a clear image reproduction and contrast, excellent quality.Speaking about the shortcomings of the DLP-technology, it should be noted "the rainbow effect" - a specific visual effect that some people notice.Although, most of the people after a certain time, no longer feel the effect.This problem can be solved by replacing the six-color light wheel on the eight- and dvenadtsatitsvetnoe.True this decision is accompanied by a significant increase in the price of goods.

LCD

The basis of this technology is w / in-matrix, which transmits itself through the light flux emitted from the lamp.Reaching the surface of the matrix, the light rays are reflected by the flow of micro-mirrors.Refracting, they are deposited on the lens, and after that - to the screen."Downside" of this technology can be called a screen door effect - the presence of the distance between the particles of the matrix, which creates a low-resolution picture step.It is in this, LCD-projector DLP- inferior congeners.Although the number of LCD-, with samples priced from $ 2,500, equipped with three w / c-matrix instead of one, and can ensure that broadcast saturated, bright and clear visuals.

CRT

CRT (from the English cathode ray tube -. Cathode-ray tube).At the heart of this technology is the presence of three picture tubes, each projecting a beam of different colors (green, red and blue).The imposition of these rays and gives a full-color image, and the combination of these streams of light is so problematic that these devices are now almost does not apply.

LCoS LCoS (English Liquid Crystal on Silicon -. Liquid crystal on silicon).This technology is the third largest in the segment occupied by the market after the LCD and DLP.The basic parts of this projector are: display with three-chip circuit manufactured by LCoS technology, a mercury lamp and a polarizing filter.This technique uses reflective matrix and not translucent, as in LCD-technology.Projectors made by this technology, can boast of reduced screen door effect, no flicker and rainbow effects.LCoS-chips stand stronger radiation than DLP- and LCD-analogues, because it is equipped with a cooling substrate.That is why, LCoS-technology is so popular in the manufacture of the most powerful installation translators.on the basis of the technology products do not enjoy mass popularity, but firmly taken its place in the highest level of quality sector.These projectors are very popular in the professional environment (digital projectors for large theaters, as well as projectors, used to visualize the effects of flight simulators).DreamVision, Sony, CrystalView, JVC, LG, Canon, Barco - that's the most well-known companies that produce LCoS projectors-today.

Laser

laser projectors are used for the decoration of entertainment shows and discos by creating graphical effects.These products find application in restaurants, clubs and entertainment centers.

pikoproektorov

This pocket projectors, a value not more than a mobile phone, or a micro-projector built into the gadget.Modern pico projector can create a projection with a diagonal of up to 120 inches.Their brightness up to 300 lumens.It comes with a mini-projectors, made in the form of individual units, often provides a standard tripod, integrated card reader, or USB flash drive.The energy-saving purposes in pico projector use LEDs.

Availability of additional options

• Shift lens.This option allows you to move the image, depending on the placement of the projector in the room.
• DVD- drive..
• USB-ports, etc.

Here you need to soberly assess the specific case, and honestly ask yourself the question: "Do I need this feature at all?Or I can easily do without it? ".After all, the presence of additional options means unforeseen costs.So why spend money on something that you do, and do not need?

Noise

permissible to consider the noise level of 30-35 dB.Exceeding this value causes a feeling of discomfort.

Mounts

In any configuration has a ceiling mount, as well as height-adjustable stand-leg.Holder for ceiling mount will have to buy separately, because its presence in the kit is not provided.

source of continuous power

This device is designed to protect the projector lamp from voltage fluctuations in the network and abrupt shutdowns.Otherwise, it may burn out.This device too, will likely have to be purchased separately.

Short-projectors

This decision is a direct response to this popular question: "And what is the projector should be chosen for a small room?»

Projectors such a plan suitable for showrooms with limited space, are used to create largepictures at a small distance from the projector to the screen.

Projectors-3D Vision

Currently 3D Vision-projectors are no longer luxury items (about $ 1,000).To create a home theater use, the computer must be equipped with a certain graphics card.Do not do without special stereoscopic glasses (another + $ 200).The only drawback is that the bulk of views need to stock stereo glasses for all viewers, which translates "a lot of money."
