Thank you for the response. The cables are all under 3 meters and are not active cables. The bios and the R9 290 card are up to date. Yes, the hub does need to be power cycled with 5 monitors in order to work, though still not completely stable. Not sure where to find the firmware version, being connected though the GPU….
The serial number is 60201512140011. Not sure if you can find what firmware was shipped with this unit….
