What is VGA?

VGA stands for Video Graphics Array. Many people casually refer VGA to as any modern high resolution display. VGA has a particular technical meaning. In the year 1987, IBM developed the VGA. It was used to delineate a display with 640 x 480 resolution with 16 colors. At that time, it was deemed a significant improvement over the valuable color graphics option.

Though, there would be a time before IBM introduced another video standard where other card companies rapidly began to produce cards that would support these higher resolutions and color depth like the IBM’s standard of the VGA. They were termed as Super VGA modes, which were deemed as anything better than 640 x 480 resolution with 16 colors. The next standard of IBM was the XGA which provided a maximum resolution of 1024 x 768 with 256 colors. It was also capable of producing 640 x 480 resolution with 65,536 colors. Continuous improvements were made at that time in the field of technology.

You might we wondering why a cable company has so much concern about various video standards. As expected, higher resolutions and color depths signify more data flowing in the cable. As a matter of fact, the original VGA cables put in use when IBM introduced the VGA standard are no longer compatible for the modern resolution. If you are looking to purchase one, buy VGA cable from primecables.ca.

When it comes to the traditional VGA cable, it was really very simple. It encompassed 14 or 15 28 gauge of AWG wires in the jacket with 15 pin connectors on one of its ends. These cables can still be used on an older device and is compatible with low resolutions of the original VGA standard. But, as the new resolutions came into being, a new cable design would be needed. Being acquainted with the fact that the most essential data flow through the cable is the red, green and blue color data, the super VGA cables were designed in such a way that they minimize the interference from compromising the signals. Instead of using just a pair of wire for each color in the traditional VGA cables, newer SVGA cables were introduced with 3 miniature coaxial wires installed inside the main cable itself. These cables are capable of bearing high resolutions up to 2048 x 1596 with no external amplification.
