What is the monitor OSD?

On-screen text is a fairly complex but useful service in audiovisual projects where one or more monitors display information to a specific audience and where this live video or graphic display will have additional characters for identification.

This fantastic feature built into AV devices can bring an important function to any application to ease the daily work of many video wall operators. We have all been in a situation where a very simple thing can be so significant.

WHAT IS THE ON-SCREEN DISPLAY (OSD)?

On-screen text, usually called OSD, is commonly known as text that displays useful information on a screen, monitor, or TV, which is a peripheral device, to display relevant and useful information to its viewers. It is commonly known as a menu on a variety of electronic devices and is used to adjust the screen or select display options.

Usually, you may have seen it on your TV, when it displays the channel, volume, or even the time. You may recognize this phenomenon when playing video games. Many times, this feature provides settings or configuration information to your carrier. It is possible that the function of this device is particularly important for Samsung, which has announced a 32-inch monitor with a curved screen.

PROFESSIONAL AUDIOVISUAL DEVICES

When it comes to professional AV devices, this feature is used to define input and output sources, and possibly to provide actual settings and additional information for the content itself. Professional implementations support live text-over-background so that audiences or operators can view the real-time moving video in the background while viewing static text in the foreground. Real-time display of video content does not disturb static characters.

WHAT USEFUL FUNCTIONS DOES THE OSD HAVE?

The purpose of using the OSD, as embedded informational text, is to facilitate the daily work of operators in mission-critical control rooms. This feature allows them to easily identify input sources as well as output settings, so they can receive additional alerts about traffic or a particular process they monitor.

Alerts can even be started and issued. In some simple AV projects, the on-screen display contains extra information or announcements for the audience.

The main functions of OSD text on video content:

• Identify the displayed video input information
• Give the resolution and characteristics of the input signal
• Identify screens and output parameters
• Issue extra information about the operation
• Show warnings and instructions based on the situation
• Identify alarm situations and transmit them to the public

Understanding the identification data issued by the OSD seems easy enough when you have a screen in a small boardroom. But when it comes to large video walls, this feature can be very useful, especially if one can alter multiple settings of the given OSD feature.

HOW IS THE OSD ACTIVATED AND WHAT SETTINGS ARE AVAILABLE?

OSD text rendering over video content can be used in all AV solutions. Operators can use a special user interface for OSD service setup and initialization. The administrator has complex configuration possibilities:

• Define the text content
• Define the font, size, and colors of the characters
• Define the number of lines displayed
• Define the position of pixels in the video window
• Define the need and background-color
• Set the transparent display on the background
• Define the automatic display of additional conditions
• Define the time to display the OSDcontent permanently or for a certain period of time after the signal change
• Ability to quickly toggle the OSD display on and off

WHAT ARE THE MAIN FEATURES OF THE OSD?

Users can customize OSD text content, color, size, position, display time and display attributes to provide accurate information. As the customization possibilities are limitless, these features provide a unique visual effect.

HOW CAN THE OSD BE ACTIVATED?

An easy-to-use graphical user interface is available for OSD display setup and control. Major attributes like text content, font type, font size, position, and background define the display and even the control.

WHY ARE THESE OSD FEATURES USEFUL?

This exceptional feature gives you another possibility for customization that will make your installation stand out from the rest. This feature primarily serves operators who use the video wall on a daily basis. As there are multiple setting options, everyone can easily change the OSD function according to their needs, regardless of the AV application area.

WHAT IS THE OSD TIMEOUT?

The OSD timeout refers to the amount of time the information remains on the screen before it disappears. For example, when we navigate through the menu of our monitor or television, we have noticed that the information disappears after a certain time if we do not make any selection. See the following video for reference.

WHY IS THE OSD LOCKED?

The OSD lock prevents the OSD menu from opening on the screen when a button is accidentally pressed. To remove the OSD lock message, release the Menu button (if something was pressing it), and hold the Menu button again for about 10 seconds – until the message disappears.

WHAT IS OSD TIME?

OSD timeout refers to the period of time between when you stop using the menu and when the menu disappears. If your device does not have an OSD timeout, it will continue to display information until you manually exit the menu or turn off the device.

HOW IS THE OSD UNLOCKED?

The OSD lockout can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lockout appears for ten seconds. If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.
