Osd （屏幕视控系统）

附录

术语

屏幕视控系统 (OSD) 可让您配置屏幕设置，根据需要优化图像质量。它可让您使用屏幕上显示的菜单，来更改屏幕亮度、色调、大小及其他许多设置。

伽马

“伽马”菜单调整表示屏幕中间色调的灰度。调整亮度可使整个屏幕更明亮，但调整 “伽马”仅使中等亮度更亮。

灰度

灰度是指颜色强度的级别，用于显示从屏幕上的较暗区域转变到较亮区域时颜色的差异。对屏幕亮度的变更以黑白变化程度表示，而灰度是指介于黑色和白色之间的中间区域。如果通过调整 “伽马”来更改灰度，则会更改屏幕上的中等亮度。

扫描速率

扫描速率或刷新频率是指屏幕刷新的频率。当传输屏幕数据时，屏幕会刷新以显示图像，但肉眼看不到刷新。屏幕刷新的次数称为扫描速率，测量单位为 Hz。扫描速率 60Hz 表示屏幕每秒刷新 60 次。屏幕扫描速率取决于 PC 和显示器中显示卡的性能。

行频

显示器屏幕上显示的字符或图像由许多个点（像素）组成。像素由水平线传输，然后这些水平线以垂直方式排列来形成图像。水平频率的测量单位为 kHz，表示每秒在显示器屏幕上传输和显示水平线的次数。水平频率 85 表示每秒传输 85000 次水平线来组成图像，水平频率以 85kHz 表示。

场频

一个图像由许多水平线组成。垂直频率的测量单位为 Hz，表示这些水平线每秒可以形成的图像数。垂直频率 60 表示每秒传输图像 60 次。垂直频率也称为 “刷新频率”，会影响屏幕闪烁。

分辨率

分辨率是指构成屏幕的水平像素和垂直像素的数量。它代表屏幕显示的细度。

分辨率越高，在屏幕上显示的信息量越多，并适合同时执行多项任务。

例如， 1366 x 768 分辨率包含 1366 个水平像素（水平分辨率）和 768 条垂直线（垂直分辨率）。

例如， 1920 x 1080 分辨率包含 1920 个水平像素（水平分辨率）和 1080 条垂直线（垂直分辨率）。

即插即用

随插即用功能允许在显示器和 PC 之间自动交换信息，从而提供最佳显示环境。

本显示器采用 VESA DDC （国际标准）实现即插即用功能。
