HI

I have the Retina Macbook Pro with 6 displays that previous worked seemless before i upgraded to Mavericks. 2 Via Thunderbolt & 4 with the USB 3 to DVI StarTech Adapters. USB32DVIPro

I can get 1 of the USB 3 Adapters to run ok along with the 2 thunderbolts, the rest show in the System Preferences/Display/Arrangement but are just black screens and the monitor doesn't registered its attached to the computer.

Any ideas?

Thanks

James
