Method and apparatus for controlling video display device

Abstract

Abstract PURPOSE: To make it possible to drive and control plural different displays by one CRT controller by connecting an adaptor between a CPU and the CRT controller. CONSTITUTION: The CPU 11 sends display control data to a memory and a logic circuit in an adaptor(AD) 10. The AD 10 generates time signals for display devices 1, 2, corrects display control data in the logic circuit in response to a correction signal corresponding to each type and programs the CRT controller(CT) 12 by the use of the correction data. In addition, the AD 10 generates a switching signal, writes the control data in another memory, corrects the data of the memory, and reprograms the CT 12 by the use of the correction data.
