The way it reads to me, the problem is plugging the Vive directly into the card. It has nothing to do with your monitor. So why is it a big deal to plug the Vive into your GPU with an HDMI cable, rather than a DP?As a 1070 owner, it's a pretty big deal imo. Most people don't have DP monitors, but HDMI or DVI. If it's HDMI only, you need to get an adapter, which both adds to the cost of the card and the time before you can use it. I find it pretty laughable that people find a defective $400+ card acceptable.
"We are aware of user reports of an incompatibility when plugging HTC Vive into GeForce GTX 1080 using the DisplayPort connector. HTC and NVIDIA are investigating the issue. In the interim, we recommend users connect HTC Vive to the HDMI port on GeForce GTX 1080," said Bryan Del Rizzo, Senior PR Manager, Consumer Products.
