Good morning,
I’m aware that there are other threads talking about output issues on the latest proprietary NVIDIA drivers, yet I don’t think any of them have had any issues related to DisplayPort functionality. If anyone knows of an up-to-date workaround, I’d highly appreciate anyone telling me.
I use two ViewSonic VX3276-QHD monitors for my desktop, which contains a GTX960 as of now. A couple of driver versions ago, a bug manifested itself, that causes any displays connected via DisplayPort to constantly connect and reconnect. My left monitor is plugged in via HDMI, which is why the bug isn’t that much of a problem, since I still have at least one monitor to work with. My system is all up to date with the stable branch, so I hope that this problem can be resolved soon.

The output from xrandr
switches around just like in the NVIDIA settings application. So I’ll post both possible outputs (had to spam xrandr to catch it while the second monitor was detected as plugged in).
