术语

OSD (屏幕视控系统)

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。

HUB

HUB 装置是通过网络连接的多个装置的共同连接点。它用于连接单一网络上的多个 PC、视频装 置、办公装置和/LAN

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

色阶是指色彩强度的等级,显示屏幕上从较暗区域到较亮区域的色彩变化程度。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 85,000 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。
