Having the same issue here - black/blank screen. When mirroring VR screen on my machine, then can see that tracking works, controllers also work.
What I have done so far:
* clean windows 10 install
* 4 SteamVR removals/reinstalls
* 3 (at least) Vive console setups
* Have 3 DP ports on my GPU - tried them all multiple times
* Have tried at least 4 different USB3 ports
If used in "Direct mode" then the Vive Console shows error "H413: Display in use" and the image is upside down.
Probably will try to sell this device after spending a whole day trying to get this thing working. Highly frustrating.
