ABSTRACT:
A method and apparatus for providing non-DDC monitor characteristics to system software is disclosed. The present invention is primarily directed to use in personal computers. The method of the present invention includes obtaining information from a user regarding specific capabilities of an attached non-DDC monitor. This information is then stored in system storage in a format similar to that sent by a DDC monitor. A BIOS call from a video subsection receives this information when a DDC monitor is not attached and utilizes it to determine the proper refresh rate at which to set an attached video controller.
