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 ThrowA 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 ThrowA 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.

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
