Abstract
A digital display system includes a monitor arranged to receive digital display data and synchronizing signals to develop displays on a cathode ray tube. The monitor is switched between different line structure and/or color definition modes in response to the polarity of one of the vertical or horizontal synchronizing signals trains. A circuit receives this train to provide control signals to the horizontal time base and/or a color signal code converter. The time base control signal, in accordance with its binary value, controls the frequency of the time base. The color converter, in response to the control signals, either passes color signals received in parallel over six input lines without change to the cathode ray tube drive circuits or converts color signals on four of the input lines to output signals on the six lines to the drive circuits.
