I'm trying to get my work PC with Windows 7 to work with a 3rd monitor. 2 have been working fine.
On the MB is a VGA and DMI out put. I purchased a new card that has two DP's and one DMI as a dual set up. When I hook up any configuration of 3, one of them will say not connected.
I didn't find anything in the bios. The PC "sees" the 3rd monitor and shows disabled. When I enable it, the other monitor will not display.
I only have one PCI slot BTW.

The card I installed was:
NVIDIA Quadro 2000 by PNY 1GB GDDR5 PCI Express Gen 2 x16 DVI-I DL and Dual DisplayPort OpenGL, Direct X, CUDA and OpenCL Profesional Graphics Board, VCQ2000-PB

Do I need a card that does all three on one card or is it the MB limiting the 3 monitors?
