显卡(Video card、Display card、Graphics card、Video adapter)是个人计算机基础的组成部分之一，将计算机系统需要的显示信息进行转换驱动显示器，并向显示器提供逐行或隔行扫描信号，控制显示器的正确显示，是连接显示器和个人计算机主板的重要组件，是“人机”的重要设备之一，其内置的并行计算能力现阶段也用于深度学习等运算。
工具/原料：
系统版本：win10
品牌型号：戴尔I7
软件版本：Windows
方法/步骤：
介绍电脑显卡作用：
步骤1、显卡是我们电脑必备的硬件之一，无论是台式机还是笔记本，都是一定会安装显卡的。我们屏幕的显示是否正常都依赖于显卡的工作。如果屏幕画面显示有问题，一般情况下也是显卡出了问题。今天就向大家介绍一下显卡有什么用。
步骤2、显卡又叫做视频卡、视频适配器、 显示适配器等，显卡是架接在主机与显示器之间 ，它起到的作用是控制电脑的图形输出，负责将CPU送来的的影象数据处理成显示器认识的格式 ，再送到显示器形成图象。
步骤 3、主要包括以下四个步骤：(1)CPU将数据通过总线传送到显示芯片;(2)显示芯片对数据进行处理 并将处理结果存放在显示内存中;(3)显示内存将数据传送到RAMDAC并进行数/模转换;(4)RAMDAC将模拟信号通过VGA接口输送到显示器上。
总结：
显卡起到的作用是控制电脑的图形输出；
负责将CPU送来的的影象数据处理成显示器认识的格式；
再送到显示器形成影像。
