DXGK_DIAG_MONITOR_STATE specifies the state of the monitors according to the miniport driver, indicating to the operating system (OS) whether the monitors are ready to receive the pixels.
DXGK_DIAG_MONITOR_STATE_UNINITIALIZEDReserved for OS use during diagnostic initialization.
DXGK_DIAG_MONITOR_READYThe monitor is initialized and setup, and is ready to receive pixels.
DXGK_DIAG_MONITOR_NOT_READYThe monitor is not initialized or setup correctly, and is not ready to receive pixels.
DXGK_DIAG_MONITOR_READY_NOTAPPLICABLEThe driver doesn't know the current state of the monitor. This value should be used only for monitors for which the driver has no insight into monitor state.
The DXGK_DIAG_MONITOR_STATE enumeration is a member of the DXGK_DISPLAYSTATE_INTRUSIVE structure. It is used while gathering display diagnostic information via calls to DxgkDdiGetDisplayStateIntrusive.
In many situations, the driver needs to initialize the monitor and set it up (typically by sending a command sequence) before it can start sending pixels to the monitor. Additionally, there might be some driver-initiated negotiation/handshaking done with the monitor before pixels can be sent. DXGK_DIAG_MONITOR_STATE specifies the final state of the monitors according to the miniport driver, indicating to the OS whether the monitors are ready to receive the pixels.
[!NOTE] In some cases (like DisplayPort), DXGK_DIAG_MONITOR_STATE might overlap with DXGK_DIAG_DISPLAY_LINK_STATE. The purpose of this enumeration is to get the overall current status of the monitor irrespective of the bus/link state.
