英语翻译
The traditional output device of a person computer has been the CRT (Cathode Ray tube) monitor.Just like a television set (an older one,anyway) the CRT monitor contains a large cathode ray tube that uses an electron beam of varying strength to "paint" a picture onto the color phosphorescent dots on the inside of the screen.CRT monitors are heavy and use more electrical power than flat panel displays,but they are preferred by some graphic artists for their accurate color rendition,and preferred by some gamers for faster response to rapidly changing graphics.
Monitor screen size is measured diagonally across the screen,in inches.Not all of the screen area may be usable for image display,so the viewable area is also specified.The resolution of the monitor is the maximum number of pixels it can display horizontally and vertically (such as 800*600,or 1024*768,or 1600*1200).Most monitors can display several resolutions below its maximum setting.
Your computer must produce a video signal that a monitor an display.This may be handled by circuitry on the motherboard,but is usually handled by a video card in one of the computer's expansion slots; often the slot is a special one dedicated to video use,such as an AGP slot (Accelerated Graphics Port).Video cards are also called video display adapters,and graphics cards.Many video cards contain separate processors and dedicated video memory for generating complex graphics quickly without burdening the CPU.These accelerated graphics cards are loved by gamers.

过去个人电脑的传统输出设备是CRT（阴极射线管）显示器.有点像那种老式电视机.CRT显示器里包含一个巨大的阴极射线管,阴极射线管里射出不同强度的电子束在显示器屏幕的内壁上显示出各种颜色的荧光点,从而“画出”了图像.CRT显示器比较笨重,且耗电量大于平板显示器,但仍有许多图像艺术家和游戏玩家喜欢用CRT显示器,因为CRT显示器的色彩显示比较准确,响应速度也更快.
显示器的尺寸指的是屏幕对角线的英尺长度,不是所有屏幕面积都是用来显示图像的,所以可视区域也是有限制的.屏幕分辨率是指屏幕水平方向和垂直方向能显示的最多像素点（比如说800*600,或着1024*768,1600*1200）.大多数显示器除了能显示最大分辨率,还能显示一些更低级别分辨率.
显示器要能显示,你的电脑就得产生视频信号.这可以由主板上的电路控制,但通常都是由电脑的扩展口上的显卡完成；通常这个扩展口是专门用于视频处理的,例如AGP接口（加速图形接口）.视频卡也被称为显卡.大多显卡包含独立的处理器和专用的显存,这样就可以在不加重CPU负担的情况下迅速产生复杂图像.游戏玩家们都喜欢这种显卡.
