I have no idea what is going on but after a morning of troubleshooting I am at a loss. I am running on Windows 10 Home latest (Microsoft Windows 10 Home, Version 10.0.18363 Build 18363).
I have a GeForce RTX 2080 Ti, it has 3 DisplayPorts and 1 HDMI input.
Up until this morning I had this setup:
- Main: 4K 144hz DisplayPort Monitor.
- Satellite: 144hz DisplayPort Monitor.
- Satellite 2: 60hz HDMI Monitor.
The last DisplayPort I use for my Valve Index VR headset when I am playing.
This morning the main display would not work, I tried swapped cords around on different ports, I did a fresh uninstall and reinstall of the latest display driver. I used a HDMI (Monitor) to display port (PC) cable on my DisplayPort Satellite monitor to see if it was the cord since I did not have an extra DisplayPort cable and it then let my main and satellite to work, the HDMI is no longer working now but I have my 2 main ones.
I then ordered a new DisplayPort cable for my main monitor to see if it was an issue with the cable, but plugging it in immediately turns off my main display and my HDMI monitor comes back on, I am so baffled on what is happening.
I can actually get it to work in a very specific port configuration and if I unplug the HDMI from the 3rd satellite the main monitor stops working again, so I temporarily have a fix but I occasionally hook up my satellite monitor to a laptop and would like to still solve the root problem.
Thanks in advance for any help, here is my system info:
