垂直频率, 水平频率, 隔行扫描和非隔行扫描法, 即插即用, 分辨率

术语

点距

显示器上的图像是由红、绿、蓝三种光点组成的。这些点越靠近，分辨率就越高。相同颜色的两点之间的距离叫做“点距”。

单位：mm

垂直频率

屏幕必须在每秒钟内被重复绘制多次才能给用户创造并显示出一个图像。每秒钟的这种重复频率就叫做垂直频率或者翻新率。

单位：Hz

例子 : 如果同一个光束每秒重复 60 次，则可将它视为 60 Hz。

水平频率

沿水平方向扫描一条连接从屏幕的右边缘到左边缘的线所用的时间叫做水平周期。水平周期的倒数叫做水平频率。单位：kHz

隔行扫描和非隔行扫描法

从顶部到底部依次显示屏幕的水平线的方法叫做非隔行扫描法，而先后给出奇数线和偶数线的方法则叫做隔行扫描法。大多数的显示器用非隔行扫描法以保证图像清楚。隔行扫描法与电视机里用的那种一样。

即插即用

这是一种为用户提供最佳质量的屏幕的功能，它允许计算机和显示器自动地交换信息。这种显示器遵守即插即用功能的国际标准VESA DDC.

分辨率

用来组成屏幕图像的水平和垂直的点的数目叫做“分辨率"。这个数字表示了显示的精确度。

例子: 如果分辨率是 1280 X 1024, 这就是说屏幕是由1280个水平的点 (水平分辨率)和 1024 条垂直的线(垂直分辨率)所组成的。

使显示更清晰

1.按照下述的标准，在计算机的控制面板当中调整计算机的分辨率和刷新率，就可以享受到最好的画质。倘若液晶显示屏的画面没有达到最佳，您看到的画面质量可能不均匀。详细情况，请参看手册。

{分辨率: 1280 x 1024

{垂直刷新率(刷新率): 60 Hz

2.当您清洁显示器的外部时，请用柔软的织物蘸取少量推荐的清洁剂，把它擦亮。不能让液晶屏部位受力，但是以外的地方可以轻柔的擦净。如果过分用力，有可能在上面形成划痕。

3.如果您对画面的质量不满意的话，您可以按下窗口终止按钮，使用显示屏上的“自动调整功能”，使图片达到更好的质量。如果自动调整后仍有噪音，请使用细调/粗调功能。要了解详细的调整方法，请查询用户手册。

4.如果观看某个固定图像的时间过长，则可能会出现画面残留或模糊不清。

如果需要从监视器离开过长一段时间，则请改用节电模式，或者将屏幕保护程序设为一个移动图像。
