I have 2 Dell 27″ monitors attached via DisplayPort to CSV-5200 going to Surface Pro 4 running Windows 10. When computer goes to sleep, every so often when coming back out, the monitors disconnect (can’t see them at all in Display Settings). If I unplug the USB power and re-plug it in, something that does the trick (pain though). Other times, that doesn’t work and I have to reboot the Surface Pro 4. Suspect this is not expected behavior on the MST?
I have not tried replacing all the cables and checked here first as that starts costing money and time 🙂
CSV-5200 Rev A3-2.1 FW 0.45 511.
Thanks for any help.
