A display control device includes a controller, a scaling engine, a timing controller, a selector and an interface circuit. The controller is for providing a mode-control signal. The scaling engine is for producing a first interface signal. The timing controller is for converting the first interface signal into a second interface signal. The selector selects either the first interface signal or the second interface signal to serve as a reference signal according to the mode-control signal. The interface circuit converts the reference signal into an output signal according to the mode-control signal. When the mode-control signal is under a first mode, the output signal is virtually the first interface signal. When the mode-control signal is under a second mode, the output signal is virtually the second interface signal. When the mode-control signal is under a third mode, the interface circuit converts the first interface signal into a third interface signal to serve as the output signal. When the mode-control signal is under a fourth mode, the interface circuit converts the second interface signal into a fourth interface signal to serve as the output signal.
