Plug and Play Design for Monitors

The items in this section summarize PC 98 requirements for Plug and Play.

10. External monitor meets DDC2B and EDID standards

Required

This requirement is based on DDC2B, which defines the communications channel between the display and host system, and on the EDID standard, which defines data formats for configuration information. This requirement includes the identification string and other EDID data that the monitor sends to the system.

Use the established standard or (if necessary) detailed timings to indicate the maximum resolution that the monitor will support. Using either the established or standard timings will result in greater flexibility when using detailed timing descriptor blocks.

The following are monitor descriptor definitions:

FD (monitor range). This information is essential for enabling the operating system to calculate the optimal refresh rate for any selected resolution.

FC (monitor name). Up to three detailed timing blocks can be used to incorporate the company and model name. These descriptors will be concatenated for a single string, and the blocks must be used in the order in which they are to be concatenated.

FF (monitor serial number). If provided, this information will be placed into the registry for easy access by asset-management software.
