Running an HP Pro 6300 (Product# C7B18UT#ABA) and trying to get 3 monitors to function on this unit. I have added an HP nVidia NVS 300 PCIe graphics card to this unit, and that handles 2 of the monitors just fine using a split-tail adapter from the card. My thoughts were I could then add a 3rd monitor using the DisplayPort. So I've got an IOGear DisplayPort-to-VGA adapter and have hooked up a 3rd monitor but no dice. Monitor says "no signal" and can't see it in Windows 7 at all. I've tested the adapter separately from the system and it does work, so the adapter isn't broken. Am I running up against a cheap hardware config that prevents onboard video from working when also using an add-on display card?
