The Video Graphics Array (VGA) has been used for connecting display devices for many years. VGA is designed to carry Video data. The same VGA cable can support many VGA resolutions, ranging from 640×400px @ 70 Hz (24 MHz of signal bandwidth) to 2048×1536px @ 85 Hz (388 MHz).
VGA cables carry analog components like RGBHV (red, green, blue, horizontal sync, vertical sync) signals. As signals are analog a good quality cable must be used for transmission of higher resolution videos. A quality cable should not suffer from signal crosstalk (signals in one wire induce unwanted currents in adjacent wires). Higher-quality cables are typically coaxial wired and insulated which make them thicker.
There are HDMI-to-VGA and DVI-to-VGA adapters available in the market. HDMI/DVI to VGA adapters do not carry the audio channel so separate audio cables must be used.
