Key Features

Type: LCD projectors project the images via an LCD screen. These are the most modern projection equipment. The video projectors are older and work with transparencies. DLP (Digital Light Processing, Digital Light Processing) are the same generation as LCD projectors and offer a resolution and a high quality picture clarity. CRT projectors are older and use a projection method based on three LCD couleurs.Projecteurs
Contrast Ratio: Ratio of the level of the purest white and the black level of the most extreme. The higher the contrast ratio, the higher the projector is capable of displaying subtle shades of color, even in bright rooms.
Two methods are used to measure the contrast ratio.
The first, called "Full On / Off", measures the ratio between the amount of light emitted when the projector displays an all white image (full on) and the amount of light emitted when the projector displays an image completely black (full off) . The second method, method or ANSI (American National Standards Institute), 16 is to project black and white rectangles alternating. The ANSI contrast ratio is calculated by dividing the averageof light emitted by the white rectangles by the average amount of light emitted by the rectangles noirs.300: 1

Form Factor: The format describes the size of the projector:

Small portable and lightweight, portable projectors are easy to transport.

Office desktop projectors are larger than portable projectors designed to be placed on a horizontal surface stable. They can be moved, but it takes some effort.

Fixed mounted projectors are larger and can be installed on a vertical surface or hanging from the ceiling using special fasteners. Once installed, they are supposed not to be déplacés.Portable

Image

Max. (Native): The native resolution indicates the resolution of the output signal from the computer via the projector. In general, the input signal (native) from a computer is automatically converted according to the resolution settings on the projector. During the conversion process, the resolution is obtained by treatment of both hardware and software of the image, called recadrage.854x480
Aspect ratio: The height / width ratio indicates the ratio between the width of an image and its height. If it is possible to change the size of an image, the height / width remainse constant.16: 9 (widescreen)
