Somewhere between 2017-07-17 and 2017-08-12, my system stopped recognizing my graphics card. After the upgrade, I still get picture, but i go from having the ability to extend monitors, to having two monitors with duplicate images. The GPU is AMD R7 370. I read that support from AMD was stopped, but is there a way to fix this dual monitor problem I'm having?
