Embodiment Construction

[0016] The principles of the present invention provide improved graphics performance using an inventive VGA connector with internal support for one or more of fusing, filtering, shielding, and controlled impedance. While the inventive VGA connector is beneficial in many respects, it is in many respects interchangeable in size with a standard VGA connector and pinout, and mates with a mating connector. At least some embodiments include an integrated DAC to provide an analog output.

[0017] For convenience, the standard VGA pinouts are provided below. Because the pinouts are standardized, the following does not describe specific pinouts. Instead, the following sections discuss the pins and connections related to power supplies, logic signals, and analog voltages.

[0018] Pin 1 Red output

[0019] pin 2 green out

[0020] Pin 3 blue out

[0021] Pin 4 monitor ID2 in

[0022] pin 5 ground

[0023] Pin 6 Red Return

[0024] Pin 7 Green Return

[0025] Pin 8 Blue Return ...

Abstract

An improved VGA connector that supports enhanced graphic performance by internally incorporating one or more functions of fusing, filtering, shielding, and the controlling of signal line impendances. The improved VGA connector is dimensionally interchangeable with many aspects of standard VGA connectors, and use standard pin-outs that mate with mating connectors. Integral DACs can be included to provide analog outputs.

Description

technical field [0001] This invention relates to computer connectors. More specifically, embodiments of the present invention relate to VGA connectors with integral electronics. Background technique [0002] Almost all personal computers use the same type of 15-pin monitor connector. Because this connector was used in the original IBM VGA card, it is often simply called the VGA connector. Because the VGA connector is so widely used, it serves as a standard that enables different suppliers of graphics display electronics to provide equipment that mates with displays from different display suppliers. [0003] While the VGA connector has been very successful over the years, it has several disadvantages that have become more pronounced with the advancement of displays and computer systems that drive the displays. First, the VGA connector is not particularly well suited for high-resolution video graphics systems. This is because VGA connectors do not provide properly defined ...
