The following are the primary terms that are used with OPM:
The physical output connection between the graphics adapter and a display device.
The type of protection that can be applied to a video signal that is passed through a graphics adapter's connector. More than one type of protection can be applied to a single connector.
The level of protection that is applied to a video signal that is passed through a graphics adapter's connector. The level value is dependent on the protection type.
