| ANSI Lumens | Standard brightness measurement in an LCD projector. Measures the level of brightness at the screen of a projected image. |
| Aspect Ratio | The ratio between the width and the height of a screen. A standard TV/Monitor has an aspect ratio of 4:3, a standard wide screen (HDTV) has an aspect ratio of 16:9. |
| Contrast Ratio | The ratio of maximum white to minimum black on the projected test picture. The larger the ratio the higher the contrast. |
| DLP® | Digital Light Processing™. A technology developed by Texas Instruments that reflects light off of the surface of a Digital Micromirror Device (DMD)™. This allows for a more clear, high-definition processing that gives microportable projectors the same presentation capabilities as larger projectors. |
| DMD™ | Digital Micromirror Device™. A chip developed by Texas Instruments that consists of thousands of tiny, moveable mirrors that reflect light to create clear, precise images that can be displayed. |
| Hertz (Hz) | A unit of frequency equal to one cycle per second (vertical scan rate is measured in Hertz). |
| Horizontal Scan Rate | Measures the speed it takes for a monitor to draw a line from one side of the screen to the other. Measurement in kilohertz. |
| Lumens | Standard unit used for measuring brightness. |
| NSH Lamp | A certain category/type of lamp by a manufacturer. |
| NTSC | National Television Standards Committee. This is a standard for the United States, Canada, Japan, Taiwan, South Korea, Mexico, and certain South American countries. References 525 lines of resolution with a refresh rate of 60 Hz. |
| PAL | Phase Alternate Line. This is a television standard for the majority of Western Europe, Asia, South America, Australia and Africa. References 625 lines of resolution with a refresh rate of 50 Hz. |
| Resolution | The number of pixels that makes up screen area.
VGA: 640 pixels x 480 pixels
SVGA: 800 pixels x 600 pixels
XGA: 1024 pixels x 768 pixels
SXGA: 1280 pixels x 1024 pixels
SXGA+: 1400 pixels x 1050 pixels |
| RGB | Red,Green, and Blue. These three colors make up the color spectrum. |
| RS-232C | An interface between a computer and a serial device, i.e. printer. |
| SCSI | Small Computer Systems Interface. |
| SECAM | This is the television standard for color processing and broadcasting. Standard in France, Eastern Europe and some other countries. |
| SVGA | Super Video Graphics Array. Has a resolution of 800 pixels x 600 pixels. |
| S-Video | A Video signal format. A VCR with higher resolution than normal composite video. (S-VHS) |
| SXGA | Super eXtended Graphics Array. Has a resolution of 1280 pixels x 1024 pixels. |
| SXGA+ | Super eXtended Graphics Array +. Has a resolution of 1400 pixels x 1050 pixels. |
| XGA | eXtended Graphics Array. Has a resolution of 1024 pixels x 768 pixels. |
| VGA | Video Graphics Array. Has a resolution of 640 pixels x 480 pixels. |
