Abstract
A system and method for testing the functionality of a VGA card and associated monitor. A testing and set up tool or Program is installed in a computer having an operating system. The Program provides a list of modes and timings for a plurality of monitors including the monitor being tested as part of the computer. A user of the Program selects various modes and timings to be tried. Looking at the screen of the monitor enables the user to determine which combinations of modes and timings, for example, are successful. A list is maintained for the modes and timings that prove successful or compatible. The list for compatible combinations is passed to the driver associated with the operating system of the computer. In a DOS environment, for example, the list of compatible combinations is used by the Program to write a Command Line that is used for setting up the associated CONFIG.SYS.
