Strange Dual Monitor problem with 2 LG UtraWide Monitors - EVGA GTX 1080 FTW

I am using Windows 10 with 2 LG UltraWide Monitors. Until recently it was a single Ultrawide LG25UMP and I just added the LG29UMP. Now the 25 inch has HDMI, Dual DVI, and another display type I am unfamiliar with but looks similar to HDMI. The 29" LG monitor only has 2 HDM outputs. When using this monitor on other devices (windows 10 Thinkpad Lenovo Laptop, 2 different generations of MacBook Pro laptops) no problem. When plugged into the Windows 10 gaming desktop with the GTX 1080 card it doesn't work once it leaves the MSI loading screen on a restart. This doesn't matter if both monitors are plugged in or a single monitor is plugged in. This happens on the HDMI port of this desktop. Windows does not recognize it.

I have tried various methods of detecting displays including the Windows 10 -> Control Panel -> Display -> Adjust Resolution fix that seems to fix some people.I have also made sure all drivers are updated that I know about. It is perplexing. Let me add neither monitor works off the HDMI slot. I have tried a few different HDMI cables as well. I have a plethora of them.

Now I used to have an EVGA GTX780Ti so I plugged that back in, and it also did not work with HDMI but it wasn't a problem as I was runnign the Dual Link DVI. It is perplexing as I cannot figure why HDMI would not work once the MSI loading screen goes away and the monitor remain undetectable.

Does anyone have a clue? I have really tried for a week to find an answer and combed this forum and others, and I feel like I am missing something. I am sorry if this is actually answered somewhere but I missed it.

EDIT: I also checked the BIOS to see if there was an on-board Intel GPU that could be preventing this from working once Windows 10 loads but to no avail, BIOS works fine on this monitor as stated too. Only when it goes into Windows does the monitor shut off and become undetectable.

OK, I was able to get this resolved by doing the following:

1. Double checked the graphics card was installed and seated correctly and screwed down

2. Once booted into Windows 10 go to Device Manager in the Contol Panel and go to Display Adapters. Even if it is showing the correct and updated display adapter, uninstall it.

3. Restart the computer and then if it does not automatically install the correct driver, make sure you have the latest driver downloaded and install and restart again

Now all works fine. Even I had the latest driver installed and working before the and after the update, uninstalling and starting fresh resolved this one.
