Abstract (en)
Display apparatus (130) for connection to a computer system (5) has a display screen (210) and a drive circuit (200) for generating an image on the display screen (210) in response to at least one video signal (R,G,B) from the computer system. A processor (270) controls the drive circuit as a function of control data from the computer system. The processor has interrupt servicing means (300') for detecting an interrupt signal. A communication channel (C) permits communication of control data between the processor and the computer system. An interrupt signal may be issued to the processor by input means (260). Switch means (310) selectively couples the interrupt servicing means of the processor to one of the input means and the communication channel. <MATH>
