I'm upgrading from a quadro fx3400 and I cannot get my new firepro 5100 to give me a signal to my VGA monitor. I've got a startech active adaptor for displayport to vga but I get nothing on my monitor other than the no signal message box when I boot. Motherboard is a MSI K8N Master2-FAR Dual Opteron Skt940. Any advice would be most welcome.
While PCIe is theoretically backwards compatible, new hardware can have issues with antique 11 year old motherboards. I'd highly suggest a complete system update.
