电脑显卡4种接口类型

电脑显卡4种接口类型 电脑显卡4种接口类型:VGA、DVI、HDMI、DP (2013-04-13 17:25:19) 电脑显卡全称显示接口卡(Video card，Graphics card)，又称为显示适配器(Video adapter)，显示器配置卡简称为显卡，是个人电脑最基本组成部分之一。对于显卡接口类型，主要包括VGA、dvi/HDMI、dp这四种比较常见的接口，当然还有其他的。 VGA接口是最常见，也就是我们通常的电脑显示器连接主机的那种，VGA接口是一种D型接口，上面共有15针，分成三排，每排五个。并且VGA接口扩展性比较强，可以轻松与DVI接口进行转换，VGA接口介绍如下图: 通过上面介绍了VGA接口包括15个针脚，那么15个针脚都代表上面含义呢,功能是什么呢,如下图所示: VGA接口管脚 目前大多数计算机与外部显示设备之间都是通过模拟VGA接口连接，计算机内部以数字方式生成的显示图像信息，被显卡中的数字/模拟转换器转变为R、G、, 三原色信号和行、场同步信号，信号通过电缆传输到显示设备中。对于模拟显示设备，如模拟CRT显示器，信号被直接送到相应的处理电路，驱动控制显像管生成 图像。而对于LCD、DLP等数字显示设备，显示设备中需配置相应的,/,(模拟/数字)转换器，将模拟信号转变为数字信号。在经过,/,和,/,2 换后，不可避免地造成了一些图像细节的损失。VGA接口应用于CRT显示次转 器无可厚非，但用于连接液晶之类的显示设备，则转换过程的图像损失会使显示效果略 微下降。 DVI接口:LCD显示器应运而生接口，DVI(Digital Video Interface)，即数字视频接口。它是1999年由Silicon Image、Intel(英特尔)、Compaq(康柏)、IBM、HP(惠普)、NEC、Fujitsu(富士通)等公司共同组成DDWG(Digital Display Working Group，数字显示工作组)推出的接口。 DVI接口有3种类型5种规格，端子接口尺寸为39.5mm×15.13mm。三种类型包括DVI-A、DVI-D和DVI-I的接口形式。DVI-D只 有数字接口，DVI-I有数字和模拟接口，目前应用主要以DVI-D为主，同时DVI-D和DVI-I又有单通道(Single Link)和双通道(Dual Link)之分，我们平时见到的都是单通道版的，双通道版的成本很高，因此只有部分专业设备才具备，普通消费者很难见到。DVI-A是一种模拟传输标准， 往往在大屏幕专业CRT中能看见，不过由于和VGA没有本质区别，性能也不高，因此DVI-A事实上已经被废弃了。如图所示: of sampling and sample size shall not be less than 5 pieces of each shipment.
