I have just upgraded my computer from Win 8.1 to 10. I was running three monitors from my NVIDIA GeForce GTX 745 but after the upgrade only one monitor is working. I have tried detecting the others via the change display resolution settings but they can not see the other two monitors. When I go to Device Manager to see if it can see my graphics card it only shows Microsoft Basic Display Adapter under Display Adapters. How can I get my monitors back?
