Not able to run Sample application with Oculus Rift

[gbhatt07]

Hello,
I was trying to run the sample RenderManager application on Oculus Rift DK2 but as soon as I am launching the application its crashing with the error:

Aug 10 16:40:33.073 error [RenderManagerNVidiaD3D11]: OSVR RenderManager Warning: Got error from NVIDIA API: NVAPI call returned -180 (hex: ffffff4c)
Aug 10 16:40:33.073 error [RenderManagerNVidiaD3D11]: [NVAPI_INVALID_CONFIGURATION]
Aug 10 16:40:33.073 error [RenderManagerNVidiaD3D11]: Could not acquire display access for vendor ID 53822 for display 0

Does this mean my NVidia GPU is not supported? but I am able to run same application in HTC Vive.

I am using oculus 1.6.0 SDK and runtime.

Attached are the server and application logs.

Thank you.
