Hi, teedog.
I’m bring some news you might be interested in.
First of all, taping DP cable didn’t work for me.
This time, I did a wild experiment. I configed the left-side monitor as the middle display in NV surround, and guess what? The left one started to go black!
So it’s always the NV-surround-defined-middle display that goes black no matter where it’s physically placed.
After I found that, I disabled NV surround and use SRWE to setup triple screen manually. I played DR2 for almost an hour, no black screen any more. However, there are some games requiring NV surround, so this won’t a perfect solution.
Also, I might be wrong about the EMI interference conclusion before. There might be some sort of interference. But it does not affect monitor directly. It more like affects the PC which causing some nv surround bug.
After all the experiments I did, the black screen only happens when all these conditions are met.
1. triple 4k solution displays
2. nv surround is enabled
3. playing games with wheel base
