Hi,
Have you found a solution to your problem? I seem to be in a very similar postion: brand new Z840 (dual CPU) with 1x 1080ti and 1x Extreme12G on Win10 x64. Driver 10.9.4 and 10.9.5 work fine, but anything newer breaks visibility in Desktop Video, thus can not be used in Resolve.
I have checked BIOS, disabled secure boot, disable signature check in Win10 - no change. Device manager 'sees' the video card, driver versions reflects installed Desktop Video version. Swapping slots (5>4), uninstalling, re-installing, powercycling - no change.
Going from 10.9.4 to 10.9.5 initiated a firmware upgrade, but it did not change the behavior. I have set up three identical Z840s with three Extreme12Gs - so an individual hardware fault is very unlikely. BMD support is very solicitous but is not able to provide required BIOS settings.
Best
Michael
