Abstract
A computer having a video circuit which is configured by a monitor identification signal is described. The self-configuring circuit permits connection to a variety of monitor types without the need for a separate video card or other dedicated circuitry compatible with the specific monitor type. The computer automatically senses the type of the monitor to which it is coupled, then configures its internal circuitry to provide compatible video signals to the monitor. The invented computer includes a central processing unit (CPU) for executing a program to provide video data for display on the monitor. The data is stored in the computer in a random-access memory (RAM). The monitor provides an identification signal to the video circuit which then provides both the appropriate video timing signals and the video data to the monitor for display thereon. The identification signal is used to configure the video circuitry in accordance with the requirements of the monitor.
