Abstract
Methods and apparatus are provided for efficiently and intelligently communicating characteristic information in video graphics switcher environments. An intelligent video graphics switcher obtains display device characteristic information associated with multiple display devices and maintains updated characteristic information. When an event such as a connection/disconnection or switching event occurs between the video graphics switcher and a display device, the characteristic information is communicated to an appropriate host by triggering a connection/disconnection event with the host.
