ABSTRACT:
Discriminator receiving a DDC transmission request from an external computer through a DDC control, judges whether a video signal inputted from the computer is a signal of analog specification or digital specification from an analog channel input detection signal from an analog synchronizing signal detector. On the basis of the judgment result, the discriminator controls the DDC control, input channel switch and OSD switch to switch EDID data, an input channel and OSD into ones supporting the specification of the video signal, respectively. In a display monitor having a DDC function which includes a DVI-I connector, with the above constitution, a correct setting of the input channel, EDID data and the like is automatically made in accordance with the specification of the input signal.
