A Brief History of Each Connector... Developed by IBM in 1987. The VGA standard originally allowed for a display resolution of 640x480 pixels but has gone through many revisions since being introduced. The most common is Super VGA (SVGA), which allows for resolutions greater than 640x480, such as 800x600 or 1024x768. Allowed for the display of 256 colors on computer monitors. Uses RGB color (Red, Green, and Blue) HDMI to VGA adapters does not transmit audio signals. You will need separate audio cables. VGA Always shaped like a trapezoid. VGA is today's basic standard for color resolution in computer monitors. It represents the lowest common denominator for compatibility. Began to attempt to replace VGA in 1999 Designed by Digital Display Working Group in 1999. Replaced the dated technology of the Video Graphics Array. Allowed computer monitors to display a true-color pallette. HDMI to DVI adapters does not transmit audio signals. You will need separate audio cables. DVI Developed by the companies Hitachi, Matsushita Electric Industrial (Panasonic/National/ Quasar), Philips, Silicon Image, Sony, Thomson, RCA and Toshiba in December of 2002. Makes previous technologies obsolete with its high-definition capabilities. Transmits high-definition video AS WELL AS high-def audio. Can transmit up to 8 channels of audio. HDMI VGA Still Important Nearly 99% of all desktop monitors still have a VGA port 30% have only a VGA connector! More than 70% of flat-panel TVs have VGA connectors Projectors Are Primarily VGA Only "Some forecast scenarios we have done have shown VGA to phase out of most PC products by 2017, but in practicality it is difficult to envision that the legacy IT'infrastructure will not still exist a decade from now," -- Chris Connery, Vice President of PC and large format commercial display market research at NPD DisplaySearch There is always a way to convert one type of signal into another, so if you have a mismatch in devices or you need to extend the reach of your devices, you can find the right kind of adaptors to meet your needs at monoprice.com-- as well as all kinds of devices and accessories for HOME THEATER including CABLE ADAPTERS, VIDEO/AUDIO SWITCHES, NETWORKING SECURITY ACCESSORIES, COMPUTER ACCESSORIES, and INK & TONER.
