不久以前,PC显示器一般是13或14 英寸的VGA分辩率(640×480个像点)监视器.现在,处理器性能的不断提高迫使显示器要有更高的分辨率.最近多媒体的急剧发展进一步改变了显示器的发展方向,合乎逻辑的结论是:它应是各种音像器材(如扬声器、话筒和摄像机)的集中地.它还应当能在主机与显示器之间实现更先进的数字通信来支持“即插即用”功能.因此,监视器变成了很高级的外部设备. Not long ago, PC monitors were typically 13- or 14-inch VGA resolution (640x480 dots) monitors, and the ever-increasing performance of processors has forced higher-resolution displays, and the recent explosion in multimedia has further It is logical to conclude that it should be the focal point for a wide range of audiovisual equipment such as speakers, microphones and video cameras and it should also be able to support more advanced digital communications between the host and the display “Plug and play.” Therefore, the monitor becomes a very advanced external device.
