View the official Windows Driver Kit DDI referenceNo description available.
The DXGK_CHILD_DEVICE_TYPE enumeration indicates the type of a child device of the display adapter.
TypeUninitializedIndicates that a variable of type DXGK_CHILD_DEVICE_TYPE has not yet been assigned a meaningful value.
TypeVideoOutputIndicates that the child device is a video output. A video output is the circuitry on the display adapter that supplies a video signal to an external or integrated monitor (or other display device). Note that monitors, integrated LCD panels, and other devices that actually display an image are not considered child devices of the display adapter.
TypeOtherIndicates that the child device is not a video output. TV tuners, crossbar switches, and MPEG2 codecs are examples of child devices that are not video outputs.
TypeIntegratedDisplayType indicating that this target is permanently connected to an integrated display.
TypeLogicalGpuThis value represents a logical GPU. In a system with multiple physical GPUs, a logical GPU could be a virtual representation of a single GPU or a combination of multiple GPUs working together as a single entity. (Examples include CrossFile and SLI technologies.)
The ChildDeviceType member of a DXGK_CHILD_DESCRIPTOR structure is a DXGK_CHILD_DEVICE_TYPE value.
