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 DLP couleurs.Projecteurs
Display Technology: Type of technology used to project the images.DLP
Brightness: The brightness of a projector is measured in ANSI lumens. The term "ANSI" is "American National Standards Institute," the agency has developed a range of values ​​for measuring the brightness of projectors. This represents an average of 9 points on the image projected image. The more lumens, the higher the projected image is bright and clear. Brightness less than 1000 lumens provide an image of poor quality, at least to be in a dark room. In contrast, higher brightness 3000 ANSI lumens ensure good vision, even in a room bathed in sun. The number of lumens is not the onlyparameter to consider: the type of lamp and the LCD technology used and the contrast ratio, also matter. According to how these variables are set, two projectors as well luminosité2500 ANSI lumens
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 average amount of light emitted by the white rectangles by the average amount of light emitted by the rectangles noirs.3200: 1
3D Compatible: Yes
HDTV formats: 720p

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) froma 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.1280 x 720
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 remains constant.16: 9 (widescreen)
