An image displayer of a multi-screen system, which is comprised of at least two image displayers. The image displayer comprises a screen, a video decoder for performing an analog-to-digital conversion with respect to a video input signal, and a scaler for selecting a video signal corresponding to a predetermined area of the screen from video signals outputted from the video decoder by an externally transmitted control signal, and enlarging the selected video signal according to a size of the screen. Accordingly, the image displayer does not require an extra signal separator when constituting a multi-vision system and is not limited in number. Also, the image displayer can be used to receive a general broadcasting channel when it is not in use for the multi-vision system.
