什么是 VGA 电缆?什么是vga接口? what is a vga cable? what is a vga interface? 显卡处理后的信息最终输出到显示器上。显卡的输出接口是计算机与显示器之间的桥梁。它负责向显示器输出相应的图像信号。由于其设计和制造的原因,CRT显示器只能接受模拟信号输入。这就需要显卡能够输出模拟信号。 VGA接口是显卡上输出模拟信号的接口,VGA(Video Graphics Array)接口,也称为D-Sub接口。虽然液晶显示器可以直接接收数字信号,但许多低端产品为了匹配VGA接口卡,都采用VGA接口。 VGA接口为D型接口,共有15针空,分为三排,每排五个。 VGA线原本包含14根线和15个孔(第9针可作为USB供电线,也可作为盲针:空脚),其中5根传输VGA主信号,4根为传输VGA主信号的线。主要数据信号线。 CLK线DAT线地等。但从传输VGA视频的角度来看,很多有线厂家的工程师认为其他四种没有任何作用,将被省略。 所以也有类似的说法,就是没有电视数据反馈。其实就是偷工减料!这就是所谓的VGA线3+2、3+4、3+6、3+9的由来,都是指内部线数! 现在你知道什么是vga线了吗?
