2. The mobile terminal of claim 1, wherein the controller is further configured to receive information from the external display device indicating an orientation direction of the monitor window is changed into a different orientation direction, and to then control the first screen image to be displayed on the first display unit in a second display direction among the landscape direction and the portrait direction.

3. The mobile terminal of claim 1, wherein when the first screen image is displayed on the first display unit in a second display direction, the controller is further configured to control the second screen image to be displayed on the second display unit in the second display direction changed from the first display direction.

4. The mobile terminal of claim 1, wherein when the first screen image is displayed in the first display direction, the controller is further configured to control the second screen image to be displayed in the second display direction.

5. The mobile terminal of claim 1, wherein the first display unit includes a touchscreen, and

wherein the controller is further configured to control the monitor window to be generated when a prescribed touch gesture is performed on the touchscreen after the mobile terminal is connected to the external display device.

6. The mobile terminal of claim 1, wherein when the first screen image is zoomed in on the first display unit, the controller is further configured to control the second screen image to be enlarged by enlarging the monitor window on the second display unit.

7. The mobile terminal of claim 1, wherein the controller is further configured to cause the second display unit of the external display device to change a display size of the content within the second display unit according to the position of the at least one object displayed within the second display unit.

8. A display device, comprising:

an interface unit configured to be connected to a mobile terminal having a first display unit displaying a content as a first screen image;

a second display unit configured to display at least one object therein; and

a controller configured to;

receive the content from the mobile terminal,

display the content on the second display unit as a second screen image corresponding to the first screen image, together with the at least one object, wherein the at least one object is displayed at a fixed position within the second display unit and a display position of the content within the second display unit is determined to avoid blocking the previously displayed at least one object,

display a monitor window for displaying the content on the second display unit, and when the first screen image is displayed on the first display unit in a first display direction among a landscape direction and a portrait direction, control the second screen image to be displayed on the second display unit in the first display direction, and

transmit information to the mobile terminal indicating the orientation direction of the monitor window is changed into a different orientation direction even though the orientation direction of the housing of the mobile terminal is not changed.

9. The display device of claim 8, wherein when an orientation direction of the monitor window is changed into a different orientation direction, the controller is further configured to transmit information to the mobile terminal to control the first screen image to be displayed on the first display unit in a second display direction among the landscape direction and the portrait direction.

10. The display device of claim 8, wherein when the first screen image is displayed on the first display unit in a second display direction, the controller is further configured to control the second screen image to be displayed on the second display unit in the second display direction changed from the first display direction.
