Computer screen image displaying method, computer having a vertical display device, and computer program product

摘要

A computer screen image displaying method is executed after power-on of a computer and includes: receiving data associated with a detected default display mode of a BIOS of the computer and a display mode stored in a display device coupled to the computer; and determining if the default display mode of the BIOS and the display mode of the display panel match, and if so, causing a video controller of the computer to output image signals according to the display mode of the display panel, and if not, causing the video controller to output image signals corresponding to the default display mode of the BIOS. Thus, screen orientation can be controlled during BIOS POST to spare the user the trouble of changing screen orientation under an operating system environment, thereby enhancing efficiency and saving system resources.

主权项

1. A computer screen image displaying method, which is executed after power-on of a computer when a central processing unit of the computer reads and executes a basic input/output system (BIOS) stored in a memory device to begin hardware detection and image display, said computer screen image displaying method comprising:
receiving, through a receiving module of the central processing unit, data associated with a default display mode of the BIOS and a display mode stored in a display panel coupled to the computer; and determining, through a comparison module of the central processing unit, if the default display mode of the BIOS matches the display mode of the display panel; and if so, causing a control module of the central processing unit to issue via an interface circuit of the control module a control signal, which contains information associated with the display mode of the display panel, to a video controller of the computer to cause the video controller to output image signals according to the display mode stored in the display panel; and if not, causing the control module to issue a control signal to the video controller to cause the video controller to output image signals corresponding to the default display mode of the BIOS, wherein the control module issues the control signal during a power on self test procedure during a boot-up of the computer and before initiation of an operating system.
