A display apparatus and control method for improving the reliability of downloading information through a DDC communication line by cutting the connection of other ICs of the display apparatus to the video signal source when the display apparatus enters a mode where information can be downloaded into the EDID storing unit of the display through the DDC communication line. An exemplary embodiment of the display apparatus connected to an external source, comprises a data storing unit that exchanges data with the external apparatus through a bi-directional communication line; a video signal processing unit connected to the bi-directional communication line; a write function controlling unit that outputs to the data storing unit a write control signal to control a write function of the data storing unit; and a switching unit that disconnects the bi-directional communication line from the video signal processing unit according to control of the write function controlling unit.
