Hi All,

I need to keep both display adapters in D0 State even without display attached to the adapter, Is there any registry or other mechanism to achieve this.

Setup:

  • I have a discrete and integrated display adapters in a platform
  • 2 Monitors connected to integrated & Discrete adapters each via HDMI

Configuration:

  • Windows 19H1 OS - WDDM 2.6 compliant display miniport driver

Issue

  • When Monitor is disconnected from any of two adapters, DxgkDdiSetPowerState for adapter without adapter is called by Display miniport model to put the device to D3 state.



Thanks,

Vidyasagar
