PURPOSE: A video display device capable of processing digital signals and analog signals is provided to process digital signals output from a computer in a cathode ray tube monitor, and simultaneously process the digital signals and analog signals, thereby expanding a use environment range of the cathode ray tube monitor. CONSTITUTION: An analog interface unit(230) processes analog signals inputted from a computer(200). A digital interface unit(220) processes digital signals inputted from the computer. An input signal selector(240) senses a type of the signals inputted from the computer for selecting an input path. A signal switching unit(250) receives the signals for switching the input path. If the signals are inputted from the computer, the input signal selector detects the inputted signals, and switches the signal switching unit according to the type of the inputted signals for processing the digital signals and analog signals.
