Display apparatus and control method thereof
First Claim
1. A display apparatus, comprising:
- an audio signal processor to process an audio signal;
a video signal processor to process a video signal;
a connection detector to detect a connection of an external audio source to the display apparatus; and
a controller configured to control the audio signal processor to change a volume of the audio signal according to an input from a control key from a user when the connection detector detects that an external audio source is connected to the display apparatus and configured to control the video signal processor to change a characteristic of the video signal according to an input from the control key from the user when the connection detector detects that the external audio source is not connected to the display apparatus.
