System and method for managing computer monitor configurations

Described is a method and system a system and method for dynamically and intelligently configuring a computer system's video-related settings upon connection of a monitor, and/or reconfiguring upon disconnection. A monitor configuration may include one or more display mechanisms, their video settings, relative positioning, and may include power scheme data. When a monitor is plugged into or unplugged from a computer system, a monitor manager component is notified and determines the current configuration, such as based on monitor identifiers. The current configuration is searched against persisted monitor configurations seeking a match. If previous monitor configuration data is found, the previous monitor configuration is applied. If not an exact match, configuration data is constructed based on similar configuration data that is persisted, or by querying for capabilities and iterating as necessary to find a video mode that the video card and monitor can use.
