The VGA port or D-Sub 15, as it is also known, is one of the oldest ports that have been available on the computer, next to the parallel port. Unfortunately, the parallel port's existence is threatened by the popular USB port, which has replaced it almost completely.

Now only some older dot-matrix printers are still being manufactured with the port for compatibility reasons with old bookkeeping programs.

But one of the survivors has been the VGA port, which is currently being used in a large number of applications. And even though its first and foremost competitor was the DVI connection interface, now there's another standard which has been approved by the Video Electronics Standards Association (VESA), it's called the DisplayPort. The new version of the standard, 1.1, supports copyright protection technology

Bill Lempesis, VESA executive director said: "The benefits of version 1.1 are significant, and will encourage adoption of DisplayPort in new generations of computers and consumer electronics equipment. Our task groups and committees within VESA worked very hard to ensure that DisplayPort 1.1 satisfies the important objectives it is designed for, and as a result, this new version has widespread support among all the leading computer and consumer electronics suppliers."

The DisplayPort acts both as an internal and external interface for displays, and has the ability of transferring up to 10.8 GB/s of information through a four lane connection. When it comes down to it, the battle is carried out between DisplayPort and HDMI for the high definition PC interface with the biggest approval rate in the graphics industry. DisplayPort 1.1 has support for High Bandwidth Digital Content Protection (HDCP) version 1.3 and provides low voltage and low power operation.
