XPS 8900 Dual Monitors, Single Video Card

If you look at the back of the XPS 8900, there is 2 monitor connections (DP and HDMI) on the motherboard.  This would be the Intel 530 GPU that comes with it.  Then my system also came with a GT 730 PCIe card.  Currently, I have dual monitors working using the DP on the motherboard and the DVI port on the GT 730. 

I am wondering if this system supported dual monitors, but only on the internal Intel 530 card with both connections hooked there? 

I had an HDMI to DP cable that I tried, but windows never found the 2nd monitor.  So, I don't know if 2 monitors on the Intel 530 card are not supported (I am sure Intel supports this, just not sure Dell enabled this) or my cable is broken.

Ok, with a DP to DP cable and a HDMI to DVI cable, I am able to only use the onboard Intel 530 card.  So, it turns out I had the wrong cable before (HDMI to DP is not a valid path).

Is the Multi Monitor (aka: Multi Display) option enabled in BIOS setup?

How do you know Intel supports this?

I do have this enabled in the BIOS.

The Intel 530 can support 3 monitors, check below:

I will be trying the 2nd connection with an hdmi from the 2nd onboard connection to display port.  I dont think that connection  is a thing and may only go DP to HDMI.  So, i have a HDMI to DVI cable coming to aee if i can get that 2nd onboard connection working.  Will let you know how it turns out.

Both my monitors are the same model.  They have a DP, DVI and VGA port.
