Me too! I have a similar problem although I think it is related to the two graphics cards. I normally work with my laptop screen and two external monitors via the docking station. If I have Rhino maximised on the laptop screen then snap it (maximised) to an external monitor, the display ports go black. I can fix this by moving it back to the laptop screen (this fixes the display port), “restoring down” the window, dragging it so that it is spread over both the laptop screen and an external monitor, releasing the mouse, then dragging it completely onto the external monitor and maximising it. It should be noted though that I have had this happen with some other programs as well (SourceTree is a big offender) so I think it may be driver related.
I think that when you are connected to an external monitor and you open rhino on the laptop screen, it opens using the intel graphics card whilst the external monitors are using the NVIDIA. The drivers don’t seem to deal with the hand off too well.
This has been happening before and after the Creators update.
@richard_schaffranek are you able to see which graphics card rhino is using? try opening the NVIDIA control panel and see if it has a rhino profile.
