ANSI Lumen
Unit of brightness as defined by the American National Standards Institute. This value is determined as follows: project
light onto a 40-inch screen, divide the screen into 9 rectangles and measure the average brightness of each of the
rectangles. Since the brightness at the center is generally different from that of the edges, ANSI Lumen provides a more
precise measure of the projector brightness than LUX.
Backwards Compatible
Backwards compatibility for previous computer models. The SVGA (800*600) projector provides backwards
compatibility for SVGA and VGA (640*480) computers.
Compression Mode
A mode that displays video in a zoomed out format.
Contrast Ratio
The ratio of the brightest and dimmest points that can be displayed on the screen.
Convergence
The alignment of the Red, Green and Blue video signals on the projected picture on the screen.
Display Size
The Display Size is determined by the diagonal length of the LCD panel.
EGA
Enhanced Graphics Array. EGA provides enhanced graphics quality in IBM PC, XT and AT as a CGA card. (640x350
pixels for all modes)
Hz (kHz, MHz)
Hertz (Kilohertz, Megahertz). Frequency per second. (Kilo: 1,000, Mega: 1 million) Hz is used to represent the frequency
of electric signals.
NTSC
National Television Standards Committee. A TV and video signal transmission standard developed in North America in
1953. 525lines / 60 Hz
PAL
Phase Alternate Line. A method to transmit and receive color line by line. PAL is widely used in Western European
countries. 625lines / 50 Hz
SECAM
Sequential Couleur Avec Memorie. A method developed in France to transmit and receive the color TV broadcasting.
SECAM is mainly used in France and Eastern European countries. 625 lines / 50 Hz
Super VGA (SVGA)
SVGA provides a graphics resolution of 800x600 pixels. This standard includes a vertical frequency version.
VGA
Video Graphics Array. Standard output interface for IBM PS/ 2. An analog graphics card developed by IBM that supports
720x400 pixels resolution in text mode and 640x480 pixels for graphics mode. (Other graphics cards process digital
data.)
Video
The picture projection capability of a PC with a VCR, Laser disk or CD-ROM drive.
XGA
Extended Graphics Adapter. A graphics standard developed by IBM. XGA includes VGA standard and provides
1024x768 pixels of resolution.
DVD
Digital media developed to provide the advantages of CD and LD. DVD provides high quality video and audio.
External Input
External Input is provided to connect external video devices other than a TV tuner such as a VCR, camcorder, DVD
player, etc. as a video source.
Resolution
Pixels are a number of horizontal / vertical dots making up the TV screen. The resolution represents the number of
pixels on a screen. Since, the more pixels there are, the more information is displayed, select a higher resolution when
you wish to view multiple tasks simultaneously.
