Abstract
An interface apparatus and a method of writing an extended display identification data (EDID) are provided. The interface apparatus includes a data processing unit, a memory unit and a switching unit. The memory unit is coupled to a connector corresponding to the memory unit and the data processing unit via the switching unit. When the interface apparatus is being initialized, the data processing unit detects whether or not the EDID stored in the memory unit is correct. If the EDID stored in the memory unit is incorrect, the data processing unit rewrites the EDID to the memory unit.
