Abstract

PROBLEM TO BE SOLVED: To provide an information processor capable of surely displaying information on a monitor when the monitor is loaded in the booted state of a system or in the case of changing a display output destination by depressing a hot key. SOLUTION: When the cover of a note type personal computer(PC) is closed, whether a VGA monitor is loaded or not, is discriminated, and when the VGA monitor is loaded, a display output destination is set up on the monitor. When the VGA monitor is not loaded, whether a TV monitor is loaded or not, is discriminated, and when the TV monitor is loaded, the display output destination is set up on the monitor. When the TV monitor is not loaded, the display output destination is set up on an LCD. When a cover is not closed, CMOS data are read out and its display output destination is set up. When the cover is closed in the booted state of the system, the occurrence of no display is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an information processing apparatus, a display control method thereof, and a storage medium.

[0002]

2. Description of the Related Art Conventionally, in a notebook personal computer (notebook personal computer) having a power saving function, three settings (LCD, VGA monitor, LCD) are set as display output destinations.
And VGA monitor simultaneously).

[0003] In such a notebook personal computer, when a user selects three settings for display by setting up a ROM BIOS or an application, or when a VGA monitor is attached when the system boots other than the three settings, an LCD is used. And a VGA monitor at the same time. If you do not have a VGA monitor,
It was also possible to set to display only the LCD.

Further, it has been possible to sequentially change the display destination by a specific key operation called a hot key.

Further, in recent years, with the progress of graphic controllers, TV monitors (N) have been developed in addition to VGA monitors.
It is also possible to display the screen of a personal computer in the TSC system and the PAL system. As described above, in a notebook personal computer that can be displayed on a TV monitor, the setting range that can be selected as a display destination is, in addition to the above three, a TV monitor (NTSC).
System), TV monitor (PAL system), simultaneous display of LCD and TV monitor (NTSC system or PAL system), L
The simultaneous display of a CD, a VGA monitor, and a TV monitor (NTSC system or PAL system) has become widespread.

Further, in a conventional notebook personal computer capable of three settings (LCD, VGA monitor, simultaneous display of LCD and VGA monitor) as a display output destination, the lid opening / closing process is performed by SMI (system management interrupt). It had been. That is, with the lid open,
When the user closes the lid when performing simultaneous display on the VGA monitor and the VGA monitor, an SMI occurs, and the
The backlight of D was turned off, and only the display destination was the VGA monitor. When the user opens the lid with the lid closed, an SMI occurs, and the backlight of the LCD is turned on in the SMI processing, and the display destination is set to the simultaneous display of the LCD and the VGA monitor.

[0007]

However, in the above conventional example, it is possible to determine whether or not a VGA monitor is mounted, but it is not possible to determine whether or not a TV monitor is mounted. The display output destination had to be set with a setup utility such as ROM setup.

[0008] VGA is used as a setting utility.
When the monitor is set, there is a problem that nothing is displayed when the lid is closed and the TV monitor is attached at the time of booting the system.

Also, when the output destination of the display is changed by the hot key, similarly, there is a problem that nothing is displayed because the presence or absence of the TV monitor cannot be determined.

Furthermore, when changing the output destination of one display, the output destination of the display (LCD, VGA monitor, LCD and V
Simultaneous display of GA monitor, TV monitor, simultaneous display of LCD and TV monitor, simultaneous display of VGA monitor and TV monitor,
(Simultaneous display of LCD, VGA monitor, and TV monitor), so it was troublesome to change the output in order every time the key was pressed to determine the target output destination.

Accordingly, the present invention provides an information processing apparatus capable of displaying information on a monitor without fail when a monitor is mounted at the time of booting the system or when a display output destination is changed by pressing a hot key, and a display control method therefor.
