Yeah. I got black screen on this no matter what. But I was getting to the windows splash screen and I did not get black screen until I ran it first and set the resolution to 1080p.
So I have it working now... However I am using the HDMI port for this monitor and the Display port for the other. Previously I used DP for both monitors with no issue. I wanted to use the DP to make use of the 144hz.. but until I find out why its doing this I will settle for 120hz.
This shit legitimately makes no sense to me though.
Speculating here, but if it was showing stuff during boot-up it isn't a hardware issue.
The GPU and bios recognize certain connections on a GPU as the primary port, regardless of how Windows labels them (display 1, 2, 3etc...) but windows will switch to what it considers the primary display once booted.
So what might be happening is that windows (or maybe Radeon despite driver refresh) has the display assignment fucked up somehow despite recognizing the displays existence and is trying to communicate incorrectly. Thinking something like it's display 2 but Windows is trying to communicate with display 3 for some stupid reason.
Using the HDMI cable might be telling windows to communicate with the correct port
Alternatively, it could be a GPU limitation regarding bandwidth across double display port, and using HDMI instead is alleviating that
I think it's time to either refresh Windows (search for it in the search function) or try a separate install and see if the problem persists.
