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

A computer comprising:

• a display device including a display panel, said display panel being provided with a display memory device for storing extended display identification data (EDID) and
• a computing device including
• a computing memory device storing a basic input/output system (BIOS)
• a video controller coupled to said display panel of said display device, and
• a central processing unit which is configured such that, after power-on, said central processing unit reads and executes said BIOS stored in said computing memory device, receives, through a receiving module thereof, data associated with a default display mode of said BIOS and said EDID stored in said display panel, determines a display mode of said display panel from said EDID, and determines, through a comparison module thereof, if the default display mode of said BIOS matches the display mode of said display panel, and if so, said central processing unit causes a control module thereof to issue a control command to said video controller to cause said video controller to output image signals according to the di splay mode determined from said EDID, and if not, said central processing unit causes said control module to issue a control signal to said video controller to cause said video controller to output image signals corresponding to the default display mode of said BIOS.

A computer program product comprising a computer readable medium having a set of computer readable instructions stored therein which, when executed by a computer, causes the computer to execute a computer screen image displaying method, which comprises:

• receiving, through a receiving module of the central processing unit, data associated with a detected default display mode of a BIOS of the computer 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 a control signal 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.
