I recently purchased a Dell PowerEdge R750 server with NVIDIA A40 graphics card. I installed the drivers and the card was showing up in the device manager but the software was unable to see or use the graphics card. After talking with tech support the indicated the card shipped in vGPU mode. I had to use a command line tool to enable physical display mode - 256MB Bar1. Also, I switched the windows nvidia driver to WDDM mode. After doing this it appears that the OS and applications can see the card. I checked using GPU-Z.
However, I’m still having a problem with on of my software application. Also, I don’t get any video when I connect a monitor to the graphics card. I’d like to at least see video output before I continue to troubleshoot my software application (Anatomage InVivo 6).
