UEFI video out only occurs on one port

[Drak3]

I'm having an interesting issue on two Intel machines. Both will only display the UEFI over DVI, clearing the CMOS does nothing. Inconvienient to say the least, I only have 1 DVI to HDMI, and I won't get a second when I never had the issue on AMD exclusive hardware.

 

The first machine is as follows:

i7-5930K

MSI Gaming Pro Carbon

MSI Gaming X RX470 (main)

Gigabyte G1 Gaming GTX 1070

120GB 850 Evo/Sandisk Ultra II 960GB/ 2TB WD Green

 

The second, which is a brand new build and doesn't even have an OS yet:

i5-4460

Gigabyte H97N-Wifi

XFX Radeon HD7750 2GB

500GB 5400RPM HDD

In the first machine, try operating it, just with the 1070 in. It could have something to do with a conflict between the two GPUs, and try updating the motherboard BIOS to its newest version, but be careful, as if it's done wrong, it will brick the motherboard.

I've got a BIOS set to latest, and a BIOS set to the oldest. Switching between them does nothing. Taking out the 1070 or 470 hasn't done anything so far, but I've got an EFI partition to move, so I'll try a second round of GPU rearraning afterwards.

It doesn't solve the issue on the second system though, and that is a single GPU machine that I built just over an hour ago.
