发明名称 Video detection using display data channel
摘要 A method and apparatus are provided for detecting a connection associated with a display and a system having a first and second video output port. Data channel information associated with the first video output port and the second video output port are read using DDC instructions and the absence of a connection between the display and the first video output port is detected. Information associated with the absence of the connection is transferred to the display which is connected to the second video output port such that the transferred information associated with the absence of the connection can be displayed to a user in the form of an error message.
