DigitalVisual Interface is a high quality digital video connectivity standarddeveloped by DDWG - Digital Display Working Group. This connectionstandard offers two different connectors: DVI-D, with 24 pins fordigital video signals only, and DVI-I with 29 pins for both digital andanalog video signals. A third connector style, DVI-A, is occasionallyused for analog-only connections with DVI-I cables. To supportdifferent resolution requirements, the DVI specification provides forone or two video links per connector, commonly known as single link ordual link, respectively.
DVI-D Single Link - Provides for amaximum pixel rate of 165 MHz, corresponding to 4.95 Gbps, sufficientfor resolutions of WUXGA 1920x1200 and HDTV 1080p/60.
DVI-D DualLink - Provides for a maximum pixel rate of 330 MHz, corresponding to7.92 Gbps, allowing for greater color depths and high resolutions up to2560x1600.

HDMIis a digital A/V interface that supports high resolution computer-videoand HDTV as well as multiple channels of audio on a single cable. It isbackward compatible with DVI. The most common connector is the 19-pinType A. Other connector variations include Type B for dual linkapplications, and Type C and Type D for small, portable equipment suchas consumer camcorders and smart phones.

IBMdeveloped XGA/XGA-2 (Extended Graphics Array) to provide a means tooffer higher frequencies and resolutions in the "VGA" domain. Thesestandards utilize software and ID bit termination to achieve thesechanges.

Custom VGA*			Up to 1600 x 1200		31-117 kHz, 60-110 Hz

*Manygraphic card manufacturers offer super high resolution modes that arenot necessarily a standard (like XGA or VESA). Thus, a customer runningone of these non-standard modes can be displaying a graphics resolutionup to 1600 x 1200 at 117 kHz (horizontal).

Useof analog video signals allows for unlimited colors to be produced.Macintosh graphic cards are unique in a couple of different regards.First, the variety of sync formats. In the past, sync has beenavailable three different ways, and in some cases all from one card.Those formats are RGsB, RGBS, and RGBHV. Macintosh graphic cards alsooffer multiple line rates and resolutions. These rates and resolutionsare determined at boot up by the manner in which the sense lines (IDBits) are terminated within the local monitor.

TheDFP connector is a 20 pin connector. It and the DVI connector carry thesame type of digital signal (TMDS. Transition Minimized DifferentialSignaling). The DFP connector was created before the DVI, by VESA, andis only designed to carry digital video, so there is no provision tocarry analog.

CGA/EGAuses a digital signal, referred to as TTL (Transistor-TransistorLogic), for the transmission of its video signal. TTL is a signal thatoperates in an on or off state only, thus limiting the amount ofdisplayable colors. Intensity bits are used to expand available colorsup to four times the original amount. Commonly used in low resolutioncomputers.
