MORE INFORMATION

DDC is the Plug and Play standard for monitors. DDC monitors are designed to meet the Video Electronic Standards Association (VESA) standard that defines the DDC implementation. Windows 2000 automatically detects and enumerates a DDC monitor if it is connected to a display adapter that has also been designed to support the DDC standard.

Windows 2000 also installs the correct Setup information (.inf) file necessary for the video driver to set the proper refresh rate. If the monitor is incorrectly detected as a VESA Plug and Play monitor, it may not be listed in any of the existing .inf files. If this is the case, use the disk provided by the monitor manufacturer to install the appropriate .inf file. If the monitor manufacturer did not provide a disk, contact the manufacturer to obtain the correct .inf file for your monitor.

For more information on compatible hardware for Windows 2000, consult the Windows NT Hardware Compatibility List (HCL). This is a compilation of computers and computer hardware that have been extensively tested with Windows NT for stability and compatibility. Microsoft Product Support Services uses the HCL to determine whether or not a computer is supported for use with the Windows NT operating system. The latest HCL is available from the following Microsoft Web site:
