I have a 1.2 Mst Hub with 3 display ports, with 3 Active display port adapters to Dvi..All monitors show up, but will not let me activate them. Tried updating amd software, back dating you name it did everyone back too 15.7. Still nothing, im lost and i know its not the adapters its all brandnew not even 5 hours old yet. Unplugging and replugging in monitors dosnt work either. So im reaching out here, hoping someone has any idea wth is going on..
