DXGK_DIAG_DISPLAY_SCANOUT_STATE enumeration

Description

DXGK_DIAG_DISPLAY_SCANOUT_STATE indicates whether the display pipeline is currently fetching and scanning out pixels actively to the given target/display.

Constants

`DXGK_DIAG_DISPLAY_SCANOUT_STATE_UNINITIALIZED`

Reserved for OS use during diagnostic initialization.

`DXGK_DIAG_DISPLAY_SCANOUT_DISABLED`

The display hardware is currently not scanning out any pixels to the vidpntarget/monitor.

`DXGK_DIAG_DISPLAY_SCANOUT_ACTIVE`

The display hardware is actively scanning out pixels to the vidpntarget/monitor.

`DXGK_DIAG_DISPLAY_SCANOUT_ACTIVE_BLACK`

The display hardware is actively scanning out a black pixel stream to the vidpntarget/monitor but not from the frame buffer. Instead, the pixels are being internally generated by the driver/hardware to simulate monitor visibility OFF for scenarios such as DdiSetVidPnSourceVisibility.

Remarks

The DXGK_DIAG_DISPLAY_SCANOUT_STATE enumeration is a member of the DXGK_DISPLAYSTATE_INTRUSIVE structure. It is used while gathering display diagnostic information via calls to DxgkDdiGetDisplayStateIntrusive.
