Abstract
A color video monitor is disclosed which includes improved digital convergence using a plurality of memory means in which vertical convergence correction values are stored, one memory each for red, green, blue and lateral blue convergence values. Interpolation means provide additional values between the points stored in memory such that a smooth transition between successive lines of the display is achieved. The correction values stored in the memories are generated by means of a high-order polynomial function. The monitor employs synchronization circuitry which synchronizes all digital components to the supplied video signal including horizontal and vertical sync pulses and an external 36 MHz clock associated therewith.
