Samsung SP-P310ME Ansi Lumen, Backwards Compatible, Compression Mode, Contrast Ratio, Convergence

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.
