I have an MSI GE63 Raider RGB 8RF laptop with the Nvidia GTX 1070 and had experienced the black screen issue after approximately 30 seconds with my Oculus Rift S. The only workaround had been to use the Nvidia 417.71 driver. Anything newer than the 417.71 driver would result in the black screen issue. I opened a Tech Support ticket with MSI and they emailed me an updated VBIOS for my GTX 1070. My VBIOS version was 86.04.7D.00.29. The updated VBIOS is 86.04.7D.00.37. I simply unzipped the file they sent me and executed the BAT. file contained within. I then updated my Nvidia driver to the current one which is 436.15 and all is well, no more black screen.
