<P>PROBLEM TO BE SOLVED: To provide an information processor capable of outputting an image signal having an amplitude which meets standards of both an image signal output terminal of an external device and an image signal output terminal of a main body. <P>SOLUTION: A detecting section 610 detects whether the computer main body 11 is connected to the external device 200 or not. When it is detected that the computer main body 11 is not connected to the external device 200, a graphic processing unit (GPU) 116 outputs an image signal having a first amplitude in order to display an image data on a display device connected to an image signal output terminal 19. On the other hand, when it is detected by the detecting section 610 that the computer main body 11 is connected to the external device 200, the GPU 116 changes the amplitude of the image signal to a second amplitude which is larger than the first amplitude in order to display the image data on the display device connected to an image signal output terminal 301 of the external device 200. <P>COPYRIGHT: (C)2007,JPO&INPIT |
