A scanning line converting apparatus for converting the number of scanning lines of an output video signal into an arbitrary under of the scanning lines to form an output image signal. The scanning line converting apparatus includes a discriminator for discriminating an aspect ratio of a picture formed in accordance with a format of the input video signal and a display for displaying the discriminated aspect ratio. Since the discriminator discriminates the aspect ratio of the picture indicated by the input image signal and the display displays the discriminated aspect ratio, it is possible to adjust the monitor to display a picture of a proper aspect ratio based on the displayed aspect ratio.
