Definition - What does VGA Cable mean? A video graphics array (VGA) cable is a type of computer cable that carries visual display data from the CPU to the monitor. A complete VGA cable consists of a cable and a connector at each end, and the connectors are typically blue. A VGA cable is used primarily to link a computer to a display device. One end of the VGA cable is attached to the port in the graphics card on the computer motherboard, and the other to the port in the display device. When the computer is running, the video card transmits video display signals via the VGA cable, which are then displayed on the display device.
DVI connectors come in 3 varieties. 1  DVI-A can transmit analog signals, allowing it to be backwards compatible with VGA (useful for CRT monitors and LCDs of lower quality). 2  DVI-D can transmit the newer digital signals. 3  DVI-I is capable of both analog and digital. 4  In certain cases, you may need a VGA-to-DVI or DVI-to-VGA converter cable. HDMI (High Definition Multimedia Interface) In the past decade, high-definition broadcasts became the new standard of what it means to be high quality. Unlike VGA and DVI, HDMI sends both video and audio signals together. The signals are digital only; thus, HDMI is only compatible with newer devices.
