The DXGKARG_QUERYDPCAPS structure is a parameter for the DXGKDDI_QUERYDPCAPS callback.
NumRootPortsNumber of DisplayPort (DP) capable connectors on the GPU, including the one for the eDP internal panel.
DPVersionMajorValue that represents the major version of the DP protocol.
DPVersionMinorValue that represents the minor version of the DP protocol.
Subsequent transmission calls will refer to the DP connectors with RootPortIndex ranging from 0 to NumRootPorts - 1.
DPVersionMajor and DPVersionMinor is the highest version of the DP protocol supported by the driver and GPU DP root ports of major/minor versions. For example, DPVersionMajor == 1 and DPVersionMinor == 1 represent DP protocol 1.1, DPVersionMajor == 1 and DPVersionMinor == 2 is for 1.2, and so forth.
