Projectors

A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen.

Even a shadow puppet on a wall might be thought of as a forerunner of the projector. In many ways, the idea is the same; a light shines through a medium and the medium creates recognizable images on a wall or screen

A comprehensive guide to buying projectors

Projectors are used in classrooms, meeting rooms, gaming and often times as a home theater. A projector projects the image on the screen, giving the feel of being right there in the middle of the action. The image that is projected on the screen....

From the largest to the smallest displays on the planet, DLP is leading

Award-winning color accuracy

Low power consumption

Unparalleled switching speed allows built-in intelligence

Native Resolution

The native resolution of a LCD, LCoS or other flat panel display refers to its single fixed resolution

16:9 Aspect Ratio

There most common video projector aspect ratios are 4:3 (XGA & SXGA), 16:10 (WXGA & WUXGA) and 16:9 (standard HDTV, 1080p).

Projector Type

A lens is a transparent piece of glass with one or two curved surfaces. A lens uses refraction to bend rays of light as they pass through the lens. This refraction is what causes images to appear larger or smaller than they truly are

Long Throw A long-throw lens is more suitable for a larger facility, such as a convention hall, church, or college campus lecture hall. The long-throw lens offers greater reach without distortion, which means you can position the projector toward the back of the room, without having to create an obstacle midway across the room
Short Throw A short-throw lens simply refers to a lens that allows you to project large images in close or tight spaces, without blinding the presenter with bright light from the projector. These are especially useful in small conference rooms, classrooms, living rooms, and small home theaters.

Keystone Adjustment

The keystone effect, also known as the tombstone effect, is caused by attempting to project an image onto a surface at an angle, as with a projector not quite centered onto the screen it is projecting on. It is a distortion of the image dimensions, such as making a square look like a trapezoid, the shape of an architectural keystone, hence the name of the feature.

Details of the projected image

Brightness - Normal Mode

Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light.

Contrast Ratio

Contrast is the difference in brightness between the brightest and darkest parts in an image. The greater the difference, the higher the contrast.

Display Colours

The Color brightness is different from white brightness as it indicates how bright projected colors are.

If color brightness is low, colors can look dull or dark, skin tones are reproduced poorly and important details can be lost.

Additional Features

Lens Shift

Lens shift provides space to move the lens itself left and right or up and down within the projector housing. This adjustment can be made either manually with a dial or joystick, or mechanically using the menu buttons. T
