Are VGA and RGB the Same Thing?

VGA and RGB are different but related terms that are used to describe video technology. RGB, which stands for red, green and blue, is a color model used in a wide variety of applications. VGA, or video graphics array, is used specifically to connect a computer to a display.

The concept of mixing red, green and blue to obtain a wide color spectrum was in use long before computers became popular. For example, the RBG standard is used for lighting, photography, image-editing software and component cables used to connect a video device to a TV. Additionally, RGB data cables are used to connect computers to monitors, which is why many people confuse them with VGA. However, VGA technology is more than just a color standard. Furthermore, unlike RGB, VGA technology is mostly obsolete. It has been replaced by more advanced analog technology like XGA, Super-VGA and high-definition digital technology, such as a high-definition multimedia interface, or HDMI.
