Cables Made Easy
With so many audio-visual cables available, it's hard to keep track. National Projector is here to help you know what projector cables you need for your system and why.

S-Video Cable
Connects your gaming system, DVD player, camcorder or satellite receiver to imaging device (projector, LCD monitor, plasma screen, etc.), spliting the video signal into separate color and brightness channels for crystal clear picture quality. The longer the connection, the more critical the cable.

VGA/ SVGA Cable
The most common type of analog VGA / SVGA cables have three rows of pins in a D-shape shell (15-pin total) that plug into the back of your computer. The other end is usually hard wired into the monitor or attached via BNC connectors. You get a crisp monitor image, with accurate picture resolution and beautiful color. The picture to the right shows what a male VGA connector looks like.

DVI-D Cable
Digital Visual Interface cables provide a pure digital connection between digital video sources and digital HDTV display devices.

USB Cable
USB cables carry data at the rate of 12 megabits per second, which is sufficient for "medium to low-speed peripherals". This broad category includes telephones, digital cameras, modems, keyboards, mice, digital joysticks, some CD-ROM drives, tape and floppy drives, digital scanners and specialty printers. USB's data rate also accommodates a whole new generation of peripherals, including MPEG-2 video-base products, data gloves and digitizers.

Composite Video Cable
Composite video works great for VCRs, camcorders, video game consoles and many others. Most home video equipment includes composite video. There are a variety of composite video cables available, such as Composite video to S video and Composite video with RCA audio. Using Composite cable, all information�the red, blue, and green signals (and sometimes audio signals as well)�are mixed together. This is the type of signal used by televisions in the US.

Component Video Cable
Component splits the video signal into three separate signals of video information for ultimate picture quality. The first signal is the luminance signal, which indicates brightness or black & white information that is contained in the original RGB signal. It is referred to as the "Y" component. The second and third signals are called "color difference" signals which indicate how much blue and red there is relative to luminance. The blue component is "B-Y" and the red component is "R-Y". The color difference signals are mathematical derivatives of the RGB signal. Component video is available on most ultimate performance TVs, DVD players, satellite receivers, and some VCRs.
