Port drivers are modules within the Intel® Embedded Media and Graphics Driver that control SCH-specific modules such as SCH LVDS, SCH TV or add-on modules to SCH. The table below lists the attributes available to port drivers. Some of these standard attributes can be customized for specific port drivers and are detailed in the following topics:

In the attribute tables, device-specific (non-standard) attributes are highlighted in gray.
