Playback viewers doesn't work issue

Hello,

So I managed to make Resolve work for the most part, just came a cross a strange issue when playback viewers doesn;t work, they are black. Sometimes Resolves blink the videos but no real playback. See the video in the link below.
Just a side note, this happens with Nvidia and Cuda, Open CL show things but is completely unusable, Resolve freees after 5 seconds. Don't know what is up with Open CL stuff but it seems Nvidia is sabotaging things.
I am using Nvidia 430.26 driver. Should I downgrade the driver? Looks like Davinci Resolve doesn;t like Nvidia driver. Although other software that I use is fine...

having the same problem using nvidia web driver 387.10.10.10.40.128 OS 10.13.6 High Sierra

So it appears to be problem on both Linux and mac OS 10.13.6 High Sierra?

I suppose the problem is in Nvidia driver 430 in my case, downgraded to 418 series and I have the viewers working.
