I bought the following RX550 video card, startech mst hub, 1 mini dp to hdmi, and 4 mini dp to dvi cables. 4 displays are working fine in extended mode. The 5th display is detected by windows and if you do a remote session to the computer it shows 5 monitors to utilize and if you drag a window to the 5th display it works remotely but there is no output to the monitor to show anything. I'm not sure what to do next since the display is detected. From what I understand none of the adapters needed to be active so I ordered all passive. I included links to what was purchased so it might help anyone in the future trying to duplicate the setup and also to help if anything I bought is incorrect. Thanks!
