Abstract
A display circuit includes a graphics display unit for generating a graphics display signal; a first BIOS and a second BIOS electrically connected to the graphics display unit, and respectively storing a first BIOS program code and a second BIOS program code; a BIOS switch electrically for enabling one of the first BIOS and the second BIOS and disabling the other; an output switch electrically connected to the graphics display unit; a first output port and a second output port electrically connected to the output switch. When the graphics display unit loads the first BIOS program code, the output switch is switched to electrically connect the first output port to the graphics display unit; when the graphics display unit loads the second BIOS program code, the output switch is switched to electrically connect the second output port to the graphics display unit.
