Try a different port on the card....Make sure the connections are good and that the monitors are turned on.

After that, call support...

What version of the Quadro driver are you currently using? You don't have any other monitors plugged into the onboard ports, right?

Sorry but I figured it out, it was a bad Display port cable. It was a new but defected cable

That can happen.  Glad I could help.

That's why I suggested checking the connections.
