What is On Screen Display (OSD)?
The majority of displays have an on-screen interface where you can change the image. By selecting the Menu icon on the front or side of your display, you can open this menu, known as the OSD. The Plus (+) and Minus (-) keys, which are typically situated next to the menu icon, can be used to browse the menu and make changes once the OSD has appeared on the screen.
Monitors' on-screen screens differ, but the majority come with the fundamental brightness and contrast settings. Some have more sophisticated color adjustments that let you adjust specific red, green, and blue (RGB) values. Many displays also allow for orientation changes, which can be used to slightly alter the screen's angle and location. It's also possible for monitors with built-in speakers to have aural changes.
OSDs are typically found on CRT and flat-screen computers, including LCD and LED screens. Although flat screen displays' screen positions are more constant than those of earlier CRT monitors, they usually have fewer modification choices. Additionally, some more recent displays give users the option of making changes through a program interface as opposed to the on-screen display. It is a good idea to be acquainted with the OSD so you can change the display options regardless of the type of monitor you use.
