Hello all! I just installed Windows 10 Pro in my Late 2012 iMac 27' with two Thunderbolt 27" monitors using Bootcamp to install it. For some reason, Windows is not detecting one of the Thunderbolt monitors. All three monitors work when I use the Mac OS but when I switch over to Windows, only the iMac monitor and right Thunder bolt monitor works. The left Thunderbolt monitor doesn't work. When I unplug both monitors and switch them around, then the left monitor would work but not right monitor. I even tried to plug the left monitor to the right monitor's Display Port but it still doesn't work. When I tried to go to the displays settings to detect the monitor, it says, "Didn't detect another display". I tried going to the NVIDIA Control Panel and did a Rigorous Display Detection but still wouldn't work.


Mac OS Mojave

Version 10.14.6

Display adapter is an NVIDIA GeForce GTX 675MX (already updated)


Any help would be greatly appreciated. Thank you in advance and stay safe.
