Hi all,
My GTX 1080 SLI setup has been working fine until this morning.
Came back from the weekend to find my third monitor went down. It was connected to the HDMI port on the second card. Swapped out the HDMI with a DisplayPort cable and discovered that none of the ports on the second card are working.
Checked the Windows 10 updates log and discovered that there were two failed Nvidia driver updates attempts Saturday and Sunday.
Dose anyone have a clue whats going on. Is this a potential hardware issue? Could a failed Windows update be responsible?
I checked the Device Display and both cards are recognized. The Nvidia Panel sees both cards and SLI is engaged. I updated the card's driver and still no connectivity. Its just for whatever reason the second card ports are not working.
Would really appreciate any help I could get.
Thanks!

Re: GTX 1080 SLI, suddenly loss port connectivity on second card

Welcome to my world. My monitors fails to be detected, or some of them just are just shutting down for no reason since over a month. I tried everything; older drivers, format my pc, move them to a different port. It's a mess. Sometime it's fine, and sometime an updated driver will turn my two card into some "generic video device". Sometime my NV control panel is empty.... Not sure what to tell you. The SLI+surround support is awful with this series, but it became a real problem when I added an HB bridge. Since a week, some of my monitors fails to be detected upon boot. The only real fix I found is to disable both SLI and surround in Windows, remove the power cord of the buggy monitor(s) and plug it(them) back. If windows detect them all as "real" monitor (not generic), I can setup my SLI+surround properly. If all my monitors are connected to the same card, it's more stable, but I'm loosing a lot of FPS while gaming (not even sure why?). Connecting them all to the second card is the most stable setup I have found, but the stuttering in SLI drive me crazy. It's worst than running the game with just one card. Plus no monitor connected to the first card mean no bios boot info. It's pitch black until windows... In Canada, that setup have cost me 2000$. It's quite a disappointment.

If you are using 10 series GPU's in SLI in combination with HB SLI bridge and NVIDIA surround welcome to the nightmare scenario. In short its currently broken and the only atleast stable version is to run all monitors from one card and take the 25% performance hit. You can head over to the NVIDIA surround official forums and there is a kinda long thread to this issue which nvidia hasn't fixed yet. Hopefully they will fix it one day but for now they are taking they sweat time to fix this.

I know about that thread, but NV don't care about their forum. I'm quite mad at them, and I know it's not EVGA fault. Sajin

Took me 40 minutes. The driver installation was strait forward after I removed AB and cleaned with DDU.
Surprisingly, my setup refused to go in surround, while it was working before the driver update. The surround setup tool told me that my monitors add to be connected in different outputs (I used the online guide). I moved them and for the first time moving my monitors trough the ports of both cards was flawless. I did many reboots, and my 3 monitors surround config stayed.
My 4th monitors refused to show anything until I used an HDMI to DVI converter on the first card on the HDMI output. Not sure why, but it seems all good. My config also stayed after reboot.
This is the first time in weeks I'm not mad at NV, and it's seem to work!
Now it's gaming time!! :D

Sajin I am going to try tomorrow. We are using this computer for an event on the other side of the country so we had to box up all the hardware and ship it out yesterday. Flying out today and then we will have thursday and friday to try to find a solution before the show starts Saturday. Fun fun...
Thing that kills me about this is that we have been testing for the last 6 weeks with no issues, and of course the day before we ship something pops up. Ugh!
Hopefully we will have the success that NoDataQC had. We not only lost use of the ports for the second card but also experienced some lagging that was definitely not there before. I'm hoping this is all a driver issue and whatever was causing the loss of the ports was also causing the lag.
Thank you for everyone's help. I will report back what we find tomorrow :)
