Video cables come in lots of different formats – do you know the difference?  Here is all the info you need to know to make sure you use the right cable for your application.

VGA

The HD15 connector, also known as VGA (Video Graphics Array), is very common and used mostly as a video interface for computer monitors. Unlike more modern cables, the signal that is carried on this cable is analog only; and is more susceptible to outside interference. The HD15 is a High Density D-style connector that has three rows of 5 pins. On most HD15 male connectors, there is one pin (pin 9) missing in the middle row. The 9th pin is omitted because it is not used to carry any part of a computer video signal. The VGA standard was originally developed by IBM in 1987 and allowed for a display resolution of 640x480 pixels.

DVI

The DVI-I connector integrates digital and analog in same connector. The DVI-D connector only carries a digital signal. The DVI-A connector only carries analog signals. To the side of this grouping of 24 pins is a wide, flat pin called a ground bar. A dual-link interface provides two TMDS links, or groups of data "channels" that can carry more than 10 Gbps of digital video information.

HDMI

HDMI stands for High Definition Multimedia Interface. This technology carries the same video information as DVI but adds the capacity for digital audio and control signals as well. The current version of HDMI carries one TMDS (Transition Minimized Differential Signaling)  link of digital video. Found on many home theater/consumer electronics devices, HDMI uses a 19-pin connector that is held in place by friction. This connector is technically described as a Type A HDMI connector. This chart breaks down HDMI versions as it compares to screen resolution.

Displayport & Mini Displayport 

DisplayPort is an interface technology that is designed to connect high-end graphics capable PCs and displays, as well as home theater equipment and displays. Like HDMI and DVI, DisplayPort utilizes TMDS (Transition Minimized Differential Signaling) link technology to send high bandwidth video and audio signals. The 20-pin connector allows the contact point to send maximum data transfer rates of 8.64 Gbps plus 1 Mbps for its AUX channel which can carry additional data.
