Projector Cables

When searching for a cable for your projector, there is a universal problem; the lack of a universal cable for your projector! You need to know what the correct cable for you and your needs are. There are a few rules that make sense for most applications; you should always check with the retailer who sold you the projector if you’re unsure before plugging into a bad situation.

Computer applications:

Computer applications typically require one of two types of connection into your projector: HD15 or M1. If you need to run a remote control, the M1 cable plus a USB connection into the computer is often the only way to go.

HD/DVD:

Projectors usually accept signals from other video sources like HD tuners and DVD players via an “HD interface.” Most HD interfaces have what’s called a “3RCA” output meaning that a 3RCA to HD15 cable is what’s needed. If you’re using other A/V sources, you may be required to use an S-video or composite video cable.

Types Of Cables:

You may or may not be familiar with the different types of cables listed above. Here’s an overview:

M1: commonly used for display devices; most often found on projectors; the M1 can receive a variety of signals including analog video, digital video, even USB. M1 uses a 30 pin (3 rows x10 pins) connector unless it’s receiving an analog video signal in which case there are 4 additional pins in this particular projector cable.

HD15: (VGA)

Very commonly used for video interface for computers, monitors, and projectors. High density DB style connector; also called VGA. 3 rows of 5 pins.

S-Video:

Super Video first introduced in the mid 1980’s which sends analog video signal on two 75-ohm coaxial cables. Each cable delivers its own contribution to the signal; one black and white; the other color. S-video doesn’t improve resolution, a belief which was commonly held; though it does allow for more refined image quality in your projector.

DVI:

Designed for connecting a computer to LCD flat panel monitor, the DVI has found its way into the projection world with its ability to deliver digital video at close range. Primarily for home or small office settings; any distance greater than 20 feet allows for signal deterioration.

These are just a few of the most popular types of cables available for your projector. When you’re selecting your projector cables, you should determine a number of factors including type of signal, distance you’re projecting, and the audience which is receiving it. If you’re looking for the cheapest projector cables, you should do some research before settling on the best type of projector cable and provider. There are numerous projector cables available for your use and enjoyment.
