The Projector Choice

There are three different categories of projectors: LCD projectors that rely on the filtering of light by arrays of liquid crystal pixels. DLP projectors are based on modulation of the reflection of light by the micromirrors. Tritubo CRT projectors are systems that rely on technology to the common cathode ray tube televisions. When you need to buy a video projector must be aware of certain characteristics and choose the most appropriate to their needs.

A key factor is the brightness of the projector, because it defines the transmission power of the light beam that projects the projector and thus the ability to make images vivid and bright that when the environments are not completely dark. The unit of measurement is the Ansi Lumen.

To carefully assess the value of brightness suitable for your projector should bear in mind several factors, including the breadth of the environment, the average number of spectators and the general conditions of ambient light. Another important factor is the resolution of the projector, usually found in business projectors with the following resolutions

* Projectors SVGA 800 × 600 pixels
* Projectors XGA 1024 x 768 Pixels
* Projectors SXGA 1280 × 1024

Is obvious that the higher the resolution of the projector as the image will be made in a qualitative way, as long as the projector to fulfill that resolution. A final important factor is the keystone correction, as if the projector is not employed in a position not perpendicular to the plane of projection, the projected picture may become distorted distorting the image, instead of displaying a rectangle to a trapezoidal shape.The spell allows you to change this distortion.

* Sure that a front projector is the right choice for your needs vision
If you disagree with the logistics, you can have an experience “theater” of high quality at a reasonable cost.Here’s what to consider when choosing the models.

* Prefer HD
If you intend to buy a front projection system, we recommend a model HD to 1080p if your budget allows. A rapid fall in prices has made them much more accessible. The highest quality is clearly visible on larger screens.A low-cost model that includes everything would be ideal for a casual viewing.

* Weighs the pros and cons of LCD projectors, and DLP Lco
In general, projectors using LCD technology are not as good as DLP models at reproducing black, but recent improvements have enabled some LCD projectors to do quite well. Headlamps Lco of brands like Sony and JVC are becoming increasingly common as a result of lower prices and some are excellent.

* When watching a DLP projector you might see a rainbow effect
Some viewers may notice a flash of color on the eyes especially when moving bright objects on a dark background. The rainbow effect is not obvious, but once noticed, can be annoying. Many newer DLP projectors now use a system that generates the color faster, which can reduce the effect.  All DLP projectors using a single chip are affected. Only the more expensive DLP units avoid the problem by using three chips to produce red, green and blue, eliminating the rainbow effect.

* The position in the room
Before buying a front projector and a screen, imagine the room as a system. Front projectors can be placed on a table or other flat surface and put away when not in use. Most can be attached to the ceiling. If you mount the projector, be sure to place it at the distance recommended by the manufacturer, angled to avoid the rectangular image are distorted.Projectors with a slow vertical and / or horizontal position to give more flexibility. Those who can not move the lens must be mounted or positioned so that the image is centered on the screen to avoid any change that may distort the image.

* The room size and seating determine the choice of screen size.
Some projectors give you more flexibility on where you place the projector to achieve a certain size. See what the manufacturer recommends. Models with short-throw lens can be positioned closer to the projector, while the long focal lenses allow the projector to be positioned farther.

* The bigger the image you want, the greater should be the distance between the projector and screen, while the zoom provides a degree of flexibility.Please note that as the image from the projector gets larger, it becomes even more blurred, with less contrast between areas of light and dark.Consider also where you sit to watch TV.  With a 110-inch screen and HD image, the better view is about 14 feet.

* Evaluate logistics
Think about where to position the receiver for cable TV or satellite, which serves as a TV tuner, an audio system and probably a DVD player or recorder.bMost projectors have at least an entrance and an entrance HDMI video, but you may need more revenue, if not use a receiver to change the signal sources. If you want to use the projector to play, be sure to have a receipt for the computer.Front projectors can be placed on a table or other flat surface and put away when not in use.Most can be mounted on the ceiling.If you mount the projector, be sure to place it at the distance recommended by the manufacturer, angled to prevent the rectangular image are distorted. The hide cables and wires behind walls or above the ceiling may require construction work, and you should use specific cables for internal walls.

* Think of the screen
There are displays with reflective trim, designed to improve the brightness, but may have an angle of view narrower than an opaque screen. Other dark screens are designed to improve the contrast by improving black level performance, but then even with the brightness. Screens without stand can be folded and put away when not in use, some screens from wall or ceiling can be retracted manually or electronically.
