I have a nvidia 7600GS PCIe card working on E6400, P5W64 WS Pro system to support 2 monitors. I want to add a Matrox G450 PCI card to support the 3rd monitor but it doesn't work. If I install nvidia driver first, then only the monitors connected to the nvidia card work. If I install Matrox card first, then only the monitor connected to the matrox card work.
How to make them work together?
