The output of video tape players and some computers, characterized by synchronization,
luminance and color signals combined on one output cable.
The degree of difference between the lightest and darkest areas of the image.
The alignment of the red, green, and blue elements of a projected image so that they
appear as a single element.
A projection screen which is slightly concave for improved screen gain. Curved screens
usually have screen gains, which are greater than 1 but viewing angles much less than
180°. Curved screens are not recommended for use with this projector.
The Display Data Channel VESA standard enables communication between PCs and
monitors, and is based on E-EDID protocol.
A "direct digital interface" signal can be supplied to the projector via an optional digital
input module installed in INPUT 5. For example, you can input an SMPTE- 259M signal
using a Serial Digital Input Module or input an SMPTE-272M signal from a Digital HDTV
Serial Input Module.
Digital Micromirror Devices™ used in this projector for processing red, green, and blue
color data.
Located at INPUT 3 and INPUT 4, this device converts NTSC 3.58, NTSC 4.4, PAL, PAL-
N, PAL-M, or SECAM to RGB video.
The sharpness of a display from a video source.
A type of rear-projection screen which spreads the light striking it. Screen gain is less than
1 but audience viewing angles are increased.
An adjustment that affects the display of an image. Such display settings include contrast,
brightness, tint, blanking, size, offsets, and others.
The maximum frequency of the pixel clock. Also known as pixel clock rate.
The Enhanced Extended Display Identification Data standard, established by VESA,
enables properties (such as resolution) of a display device to be detected by the display
card in a controlling device such as a PC. The PC, in turn, can then output in a matching
format to fill the display. Some sources used with the projector are VESA EEDID reported.
A very rapid variation in image brightness caused by a frame rate that is too slow. (See
Interlace) See also Lamp Flicker.
The intensity of visible light per square foot.
The luminance (brightness) which results from one foot-candle of illumination falling on a
perfectly diffuse surface.
The frequency at which complete images are generated. For non-interlaced signals, the
frame rate is identical to the vertical frequency. For interlaced signals, the frame rate (also
known as field rate) is one half of vertical frequency.
The ability of a screen to direct incident light to an audience. A flat matte white wall has
a gain of approximately 1. Screens with gain less than 1 attenuate incident light; screens
with gain more than 1 direct more incident light to the audience but have a narrow viewing
angle. For example: An image reflecting off a 10 gain screen appears 10 times brighter
than it would if reflected off a matte white wall. Curved screens usually have larger gain
than flat screens.
High-definition Television (1035, 1080 and 1125 lines interlace, and 720 and 1080 line
progressive formats with a 16:9 (i.e. 1.77) aspect ratio.
