A device for receiving video signals and horizontal and vertical synchronizing signals using a flat panel display device for discriminating modes thereof, displaying the best images by automatically controlling the mode, in case the mode is unsuitable for the flat panel and a method therefor. A micro-controller discriminates modes according to the input horizontal and vertical synchronizing signals, and outputs an OSD (on screen display) control signal and pixel clock control signals according to the discriminated modes. A phase-locked loop controls timing of pixel clocks according to the pixel clock signals control of the micro-controller and outputs the pixel clocks. An analog to digital converter receives video signals, and samples the video signals according to the pixel clocks from the phase-locked loop, converts the video signals into digital video signals, and a video controller receives the digital video signals transmitted from the analog-digital converter and outputs the digital video signals to a panel driver according to the pixel clocks from the phase-locked loop and the OSD control signal from the micro-controller.
