Unable to enumerate and use DirectMode HMD displays

[bkdc]

None of the Windows APIs work with displays set to DirectMode. I tried: EnumDisplayDevices, DXGI, QueryDisplayConfig, and Core::DisplayManager.

Use of AMD libs only marginally improves the situation:

• ADL, ADLX - basic enumeration works (display is being detected, can retrieve EDID ), no resolution info is provided; creating a DX swapchain seems impossible.
• LiquidVR seems to be both deprecated and the SDK published here doesn't provide any meaningful APIs to use such displays; also see this discussion.
