• providing a display device which arranges a plurality of display areas in a display range of a display section, selects an input source of an input image to be displayed in each of the display areas from a plurality of input sources, and displays the input images of the selected input sources in the respective display areas;
• displaying a source designation panel adapted to designate the input sources of the input images out of the plurality of input sources on the display section;
• determining the input sources of the input images to be displayed on all of the display areas in response to designation of the input sources of the input images to be displayed on all of the display areas by an operation during the display of the source designation panel;
• and
• selecting the input sources determined and displaying the input images of the input sources selected,
• wherein the source designation panel includes:
• a list of the plurality of input sources,
• a first cursor for designating a first input source of a first input image to be displayed in a first display area of the plurality of display areas, and
• a second cursor, displayed concurrently with the first cursor, for designating a second input source of a second input image to be displayed in a second display area of the plurality of display areas.

A computer program product embodied in at least one non-transitory computer readable medium and comprising computer instructions executable by a computer controlling a display device including a display section and allowing the computer to function as:

• a display control section adapted to arrange a plurality of display areas in a display range of the display section and display an input image in each of the display areas;
• a source selection section adapted to select, from a plurality of input sources, the input sources of the input images to be displayed in the display areas;
• and
• a multi-screen display control section adapted to:
• display, on the display section, a source designation panel adapted to designate the input sources of the input images out of the plurality of input sources,
• determine the input sources of the input images to be displayed in all of the display areas if the input sources of the input images to be displayed in all of the display areas are designated by an operation during display of the source designation panel and a determination operation is performed,
• wherein the source designation panel includes:
• a list of the plurality of input sources,
• a first cursor for designating a first input source of a first input image to be displayed in a first display area of the plurality of display areas, and
• a second cursor, displayed concurrently with the first cursor, for designating a second input source of a second input image to be displayed in a second display area of the plurality of display areas.
