Dell Precision Rack 7910 Workstation Embedded Video Controller Issue

Hello there,

I managed to enable the on board graphics in BIOS and use my on board graphics cards for the primary display. I have 2 more monitors connected to the nvidia card.

When i select nvidia controller i get an error saying "enabled nvidia settings are not available".

Can someone please find me a solution as i dont want to plug my main display in to the video card because i still have 2 more monitors making all 4 ports occupied.

Thank you
