ABSTRACT:
An information processing unit that can switch between a simultaneous display state of the same screen by a CRT display and a liquid crystal display and a display state by only the liquid crystal display, by using a display frequency suitable for each of the display state without the necessity for re-activation of a system. The kind of usable displays is displayed on a setup screen of the liquid crystal display and a user selects a desired display. A display controller generates display signals having display frequencies suitable for the selected displays, and effects screen display of the CRT display and the liquid crystal display. Further, commands for setting the specification of the display controller are stored in advance into a BIOS ROM and a HD. When the command is executed through an input device during the use of the system, the command is executed for the display controller and the display specification is changed.
