Q: What kind of video adapter do I need for my computer?
A: The answer depends on the kind of video-out connector your computer uses and the type of video-in connector the display/projector uses.

Computers use a variety of video connectors.

The standard video connector, commonly called a VGA connector is technically a HD-15 connector.

The connector contains three parallel rows of five pins or sockets surrounded by a D-shaped metal shield that provides mechanical support, some screening against electromagnetic interference, and ensures correct orientation.



This is also the typical connector on video projectors.

A typical VGA video cable looks like this:

Some projectors may also have a Digital Visual Interface (DVI) connection. DVI is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A).

A DVI cable looks like this:

Some recent projectors and displays, and all modern HD TVs incorporate an HDMI (High-Definition Multimedia Interface) connection. HDMI can support, on a single cable, any uncompressed TV or PC video format, including standard, enhanced and high-definition video; up to 8 channels of compressed or uncompressed digital audio; a Consumer Electronics Control (CEC) connection; and an Ethernet data connection.

An HDMI connector looks like this:
