Abstract
A method and system connects a display device or other device to a computer system during operation of the system. Initially a run time EDID (Extended Display Identification Data) flag is set to a first value indicating no run time EDID is required. By monitoring for an interrupt a checking is carried out for a change to a new display device in the computer system. If no change to a new display device is detected, the run time EDID flag is checked. If the run time EDID flag indicates that no run time EDID is required, an EDID is read from a video BIOS on a graphics adapter in the computer system. If the run time EDID flag indicates that a run time EDID is required, an EDID is read from a video memory on a graphics adapter in the computer system. If a change to a new display device is detected, the run time EDID flag is set to a second value and EDID is then downloaded from the new display device.
