VGA

Descripiton

VGA接口是一种D型接口,上面共有15针孔,分成三排,每排五个。 其中,除了2根NC(Not Connect)信号、3根显示数据总线和5个GND信号,比较重要的是3根RGB彩色分量信号和2根扫描同步信号HSYNC和VSYNC针。VGA接口中彩色分量采用RS343电平标准。RS343电平标准的峰值电压为1V。VGA接口是显卡上应用最为广泛的接口类型,多数的显卡都带有此种接口。有些不带VGA接口而带有DVI(Digital Visual Interface数字视频接口)接口的显卡,也可以通过一个简单的转接头将DVI接口转成VGA接口,通常没有VGA接口的显卡会附赠这样的转接头。
