A micro-computer of a operation recoding type in a DDC monitor and control method thereof

摘要

An operation-recording type system for controlling a display data channel (DDC) monitor utilizes a control method wherein information of externally inputted signals is recorded in a storage device upon receipt of externally inputted signals; an operation corresponding to the externally inputted signals is carried out by a microcomputer; the operation corresponding to the externally inputted signals is recorded in the storage device; and the externally inputted signals and the corresponding microcomputer operations are recorded in the storage device. Therefore, the user of the monitor can easily identify the cause of abnormal operation, thereby making it easy to correct errors.
