  • PC with multiple video-display refresh-rate configurations using active and default registers
    Patent number: 6049316
    Abstract: A portable personal computer (PC) can be connected to a variety of different external CRT monitors. Configuration of each CRT monitor is performed by the graphics display driver software so that the user does not have to re-configure the graphics sub-system every time a different CRT monitor is connected. Auto-configuration of Plug-and-Play monitors occurs by reading configuration information from the monitor itself. For Windows 95, the Plug-and-Play drivers are used for auto-configuration, or for older operating systems the video BIOS display-data-channel functions is used. Older "legacy" CRT monitors that do not support Plug-and-Play are still auto-configured. The vertical refresh rate for each resolution is stored in a default register on the graphics controller chip. The vertical refresh rate from default register is copied to an active refresh-rate register when a legacy (non Plug-and-Play) monitor is detected.
