Description

IDDCX_TARGET_MODE provides information about the target mode signal, including the bandwidth needed for the mode.

Members

Size

Size of the structure, in bytes.

TargetVideoSignalInfo

A DISPLAYCONFIG_TARGET_MODE structure that describes the display path target mode, including information about the video signal for the display.

RequiredBandwidth

The display pipeline bandwidth required for this mode. The driver reports pipeline bandwidth in IDDCX_ADAPTER_CAPS.MaxDisplayPipelineRate. The OS will never pick a combination of modes across all targets that exceeds this value.
