so the setup is the following:
– Around 10 PC’s with this setup running: Windows 8.1 Pro, Newest Catalyst Pro 15.201
– All PC’s have a ATI FirePro W8100 and <a href="http://www.amd.com/en-us/products/graphics/workstation/firepro-display-wall/s400#”>SyncBoard S400 installed
– 4xDisplayPort 1.2 MST Hub (CSV-5400) with 4 screens on the Hub and 2 screens directly on the graphics card
– So all together we have 6 Displays running @ 1920×1080 / 50Hz – combined to one Display Group of 3840 x 3240 on each PC
The issue we can see on several PC’s is that the screens connected to the MST Hub stay black randomly on PC startup. The only way we found to resolve the issue, was to reboot (still random) or sometimes reconnecting the power supply of the MST Hub helps to get them running again. We also tried to connect only 3 Screens to the MST Hub, but the issue still occured randomly.
Is this a known issue or does somebody know a permanent solution?
