Abstract:
1. A method of hot-plugging a video display unit to a computer, comprising the steps of: providing the computer with a processing unit, a memory unit connected to said processing unit a digital data communication (DDC) interface connected to said processing unit, and a video card connected to said processing unit and coupled to said video display unit; while power is being supplied to said processing unit, detecting whether said video display unit is newly coupled to said processing unit, said video display unit conveying varying visual information to a user, and said processing unit processing data including the varying visual information; when said video display unit is detected as being newly coupled to said processing unit while power is being supplied to said processing unit, operating said DDC interface and said processing unit to read first data corresponding to said video display unit from said video display unit; determining whether said first data corresponds to second data stored in said memory unit; and when said first data does not correspond to said second data stored in said memory unit, storing said first data in said memory unit, determining a resolution corresponding to said video display unit, and transmitting said resolution to said video card coupled to said video display unit; said detecting step comprising operating said processing unit to carry out a polling operation periodically with respect to said DDC interface so as to determine whether said video display unit is newly coupled to said processing unit.
