Weird problem I can't figure out...

I have a GTX 980. My main monitor works fine over display port (1440p/144Hz), and my second monitor was always working fine when I was using an HDMI to DVI cable (HDMI on the GPU side). My GPU only has one HDMI input and I now need it for a capture card. So I used a pure DVI cable that works on my other PC/Monitor over, but it says no signal.

-Goes to signal right after Windows boot. I get to see my Mobo logo and the Windows Logo, but right after goes to no signal.

-Hooked it up to another monitor, exact same thing

-Cable works fine on my other PC/Monitor

-DVI input is selected.

Any ideas?

Figured it out - sort of. I fixed it anyway.

I have two cards in SLI. So I disable SLI and put the DVI cable on the second card. It worked. So I then thought, "Okay, is this a hard issues with the top/prime card or a software issues?", so I swapped the cards. So I then hard both cards plugged into the new prime.top card, and both monitors working fine... but I check the display settings and it shows "Analog Display" setting on the DVI input on the old card (now at the bottom). Weird.

So I enabled SLI again, which knocked off the ghost monitor off the second card. All is well. However, Windows would warn me on boot that I had a third monitor not being displayed. Minor annoyance but it still was pissing me off. So I then wiped all the...

Now, everything is fine.
