Windows 10 + R9 390 + HTC Vive = DisplayPort issue

Question asked by mvittiglio on Jun 28, 2017

Hey folks,

I've recently changed my setup to include an additional monitor via the DisplayPort. I immediately noticed an issue where the monitor would fail to display any output in Windows (Linux works, albeit with some minor tearing artifacts when at full resolution) though it's detected and enabled.


I currently have the other monitor connected via DVI connection and have had some strange luck getting the DP connected monitor to put up a display by messing with some settings (such as scaling) but regardless, the problem returns upon restart.


I have the latest drivers installed. I should point out that after installing the latest drivers and the new monitor I had to reinstall the HTC Vive software and Steam VR to return functionality to the Vive. Issues were present with the DP connected monitor before and after the driver update but are worse now that I've reinstalled Steam.
