OSD相關定義解釋
OSD (On-Screen Display) 屏幕視控系統。
早期的屏幕要調整設定,必須使用屏幕下方的旋轉鈕,可調整的功能較少。但是隨着技術的進步,廠商發展出一項新的 OSD 功能,可在屏幕上顯示屏幕的相關設定,操作的功能也比較多。

OSD ( On-Screen Display ) 是在屏幕上直接顯示使用者所調整的結果和設定的內容,目前許多數字式的屏幕都支持 OSD ,因此屏幕可顯示的寬度、高度、亮度、對比和色系等設定都是直接在畫面上進行,這個功能是直接由顯示器硬件所支持的,不必使用操作系統的驅動程序,即使顯示器所連接的計算機不開機也可以使用 OSD 。

on-screen display
An on-screen display (OSD) is a control panel on a computer monitor
or television screen that allows you to select viewing options and/or
adjust components of the display, such as brightness, contrast, and
horizontal and vertical positioning.
On a computer monitor, an on-screen display is usually activated by buttons on the bottom of the monitor. As an example, one button may bring up a display of the brightness and contrast levels, which may be adjusted by pressing the monitor's up or down arrow buttons.
On a television screen, an on-screen display can usually be activated either through buttons on the television set itself or through the remote control. Television on-screen displays are becoming increasingly complex and interactive. In addition to the visual calibration options, the on-screen display may allow you to view program information, search for programs, or put certain channels under parental control.
