I know this is an old thread but I came across it while having the same issue and thought Id post it solution for the next person in case it helps.
SOLUTION: in my case the issue was that the Vive was connected to the wrong HDMI. There was an HDMI connected to my motherboard and an HDMI connected to the video card.
I had mine connected to the motherboard one. I switched it to use the GPU one instead and it worked fine.
hope that helps someone out there!
