We have two HP Z420's that we upgraded to Windows 10 1803 earlier. On both computers, after the upgrade, we lost video. We ended up booting to a Windows 10 install USB and rolled back to a previous version of Windows (1709).
These workstations have Quadro K4000's in them.
One of the computers was a fresh install of Windows, pre 1803, and then upgraded that fresh install with 1803 and still lost video.
Anyone have a solution to this?
