       21 . An electronic apparatus comprising:
 a graphics control module configured to control a first display unit;
 a connector configured to connect a second display unit to the graphics control module, the second display unit receiving digital video signals and display images represented by the digital video signals; 
 a determining module configured to determine whether the second display unit is connected to the graphics control module; 
 a executing module configured to execute a video-data reproducing application program; and 
   a control module configured to control the second display unit by using the graphics control module when the second display unit is connected to the graphics control module, at the time of activating the video-data reproducing application program, the control module controlling the first display unit by using the graphics control module when the second display unit is disconnected from the graphics control module.   
   
   
       22 . The electronic apparatus according to  claim 21 , wherein the first display unit is a liquid crystal display or an analog display, and the second display unit is a DVI (Digital Visual Interface) display. 
   
   
       23 . The electronic apparatus according to  claim 21 , further comprising:
 a setup module configured to set up the first display unit as a main display unit, the first display unit being used as the main display unit when the electronic apparatus is activated.   
   
   
       24 . An electronic apparatus comprising:
 a first display unit configured to operate as a main display unit connected to a main body of the electronic apparatus;   a connector configured to connect a second display unit to the main body, the second display unit receiving digital video signals and display images represented by the digital video signals;   a determining module configured to determine whether the second display unit is connected to the main body;   a executing module configured to execute a video-data reproducing application program; and   a control module configured to control the operation of the second display unit when the second display unit is connected to the graphics control module, at the time of activating the video-data reproducing application program, the control module controlling the operation of the first display unit when the second display unit is disconnected from the main body.   
   
   
       25 . A method of controlling a operation of display units for an electronic apparatus including a first display unit, said method comprising:
 setting up the first display unit as a main display unit connected to a main body of the electronic apparatus at the time of starting of the electronic apparatus;   determining whether a second display unit is connected to the main body, the second display unit receiving digital video signals and display images represented by the digital video signals; and   controlling the operation of the second display unit when the second display unit is connected to the main body, at the time of activating a video-data reproducing application program, and the operation of the first display unit when the second display unit is disconnected from the main body.
