Has this been resolved? If so, I would love to hear the solution.It sounds like I am having the same problem. I have been battling this for about a year now. I am going to jump on to this thread, if you don’t mind….
The three monitors off the R9 290 card work fine. I cannot get any monitors on the MST hub to work properly. I can get two monitors working on the MST hub, though will not all be active if you restart the computer. In addition, I cannot put the computer to sleep, being the computer will not come out of sleep. This only happens when monitors are connected to the MST hub. If i attempt to get 3 monitors going off the MST hub (total of 6 monitors), the system becomes unstable and the screens constantly flash.
I was hoping with the release of Crimson and Windows 10 that this would be fixed. No luck.
