Windows 7 No login screen after installing new GTX 1080Ti- Fixed!

[zayaso]

Forum members,

Trying to determine what the technical issue is with my Windows 7 SSD image booting up but not displaying on my screen.
Change I made last night was to install a new GTX 1080Ti in my 5,1 system and a new Samsung 40inch 4K screen. I used to have a GTX 780 card in my systems and at the latest nvidia drivers on the Mac side.
I verified everything works by first swapping screens and verifying my GTX 780 card would display Mac OS on the new screen. That was a success so I swapped out for the GTX 1080Ti card and it booted into the Mac OS with no issues.
Now I am trying to boot into my Win 7 image and it does not display on my new screen.
My Win7 image has the latest updates and I have verified there are no Nvidia drivers loaded on my Win 7 instance. How can I get my Win 7 to boot off my GTX 1080Ti? I had none of these problems with my GTX 780.

Thanks in advance
[doublepost=1498600714][/doublepost]To validate there are no issues with my Win7 SSD, I removed all Graphics cards, installed my GT120 and connected to my old Apple 30 inch Cinema Screen. Everything boots fine.
I see Windows has an optional install of Nvidia display driver from 5/1/2017 22.21.13.8205. Should I install this?

My GTX 780 works after swapping it in... at this point only thing I can think of are windows drivers for the GTX 1080Ti. Installing the latest Nvidia drivers hoping it fixes the issue.

When I download and attempt upgrade to newest Nvidia Driver downloaded from their website, 382.53 for win 7 64bit systems, install process starts then my screen goes dark. Computer stays on. Left on overnight in this state as I was tired. Rebooted in the AM; still dark screen. Connected to my GT120 card, power cycle, system booted up and logged in.
Still confused as to how to get my

I have no clue. All I can lamely suggest is to try Windows 10 because it has different drivers.

Also if you have a Windows 7 PC handy, I'd try the card in there just to see what happens.
