HKEPC网站报道nVIDIA于13日在美国注册了一个名为VGA Connector With Integral Filter的技术专利，该技术是改良现有的15针D-sub接口，以提供更高质量的图象。

专利摘要如下:

"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."

呵呵，VGA连接器内建有滤波器？不过这个在低分下无太大作用，而高端显示器都已经纷纷采用DVI数字接口，不知道nVIDIA这个技术用于何处？也许是某些仍在使用传统VGA接口的专业显示应用吗？
